TAC-404 Electronic Control Family Specifications

The TAC-404 is a highly sophisticated, modern controller designed to operate using the latesttechnologies. The TAC-404 enlarges the air conditioner operation abilities.

General:The name of the product will be changed, by adding the character ‘S’ to the model name oradding the character ‘S’ on separate label, for example:GFL-250H will become GFL-S250H (as you can see in Tables 2A & 2B: ATEC-220 versusTAC-404 air conditioner 50Hz and 60Hz model names).For the TAC-400 two models are available: ANC-65 & ANC-88 (both three phase models).

Please be advised to the two main technical issues:

For Installation:The interconnecting cable/port has an additional control wire to accommodate the mediumoutdoor fan speed (new).

For Service:Please note that the ATEC-220 Electronic Control is interchangeable with the TAC-404Electronic Control (as a complete system, for TFE, TNL, GFL, ANL and GNL models).The TAC-490 Remote Controller is adapted to control all three Tadiran Electronic Controls(ATEC-220, TAC-404 and TAC-400 models) and can be programmed for various operations.

Important Note: for most of the new TAC-404 models, comparing to the previous ATECmodels (for example: TFE-11 comparing to TNL-S11), many parts were changed (except theelectronic), such as: indoor fan motor, outdoor fan motor etc.In some cases, the Refrigeration Cycle was changed also.

Note: All the enclosed specifications, explanations, drawing, schemes etc. are the same for TAC-400 (ANC models) unless mentioned otherwise.

Specifications and performance data are subject to change without notice.

TAC-404 Basic Structure:

The TAC-404 is composed of 3 main units:

1. TAC-460 - Display Assy. - the system “brain”, including the electronic control software(specially shaped for each model).

2. TAC-444 - Electronic Control power box - a relay unit which provides an interfacebetween the software in the Display Assy. and the air-conditioner loads (indoor fanmotor, outdoor an motor, sweep motor, reverse valve, compressor, TH-1, TH-2, TH-3and heating element).The TAC-444 is controlled by the TAC-460.

3. TAC-490 Remote Controller.

TAC-444 “reads” the 3 thermistors (TH-1, TH-2 & TH-3), using an 8-bit A/D converter thatconverts the thermistor outputs to digital data. Thermistors accuracy is 1%.

The TAC-400 (ANC) is composed of 4 main units.

1. TAC-440 - Indoor Electronic Control. 2. TAC-420 - Outdoor Electronic Control. 3. TAC-460 - Display Assy (looks like the ANL-S Display Assy but with different software). 4. TAC-490 Remote Controller.

Display Assy DIP Switches (Jumpers):4 DIP switches located on the TAC-460 Display Assy.

DIP switch no. 1 indicates whether the unit is high wall/ceiling or floor installation. When theswitch is OFF (up), the unit is floor installation, and when the switch is ON (down), the unit ishigh wall/ceiling installation.

DIP switch no. 2 indicates the compressor type. When the switch is OFF (up), the compressoris of the reciprocating type, and when the switch is ON (down), the compressor is a rotary type.

DIP switch no. 3 sets the air conditioner to Heat Pump/Cooling Only mode.When the switch is OFF (up), the unit is Heating & Cooling, and when the switch is ON(down), the unit is Cooling Only (effective from TAC-460 software version V1.51 only).

DIP switch no. 4 is for future use only (Not Connected).

DIP Switches, factory set (values in parenthesis are for 60Hz models):

Backup Memory:Programmable memory, EEPROM type saves programmed settings after a power failure(recovering to the last settings).This is pure Electronic Memory (no use with backup battery - much more reliable).

Power Failure:1. If the power failure is shorter then 20 msec., TAC-404 is not affected.

2. If the power failure is longer then 20 msec., TAC-404 stops all air conditioner operations forthe next 20 sec. After power recovery, TAC-404 recovers using the Pressure Release Routineusing the last operation settings. If the software version is V1.51 or higher and the A/C isprogrammed to 'COOLING ONLY' (by TAC-460 DIP Switch 3), then the TAC-404 willenter to 5 minutes delay.

Communication Failure:In case of a communication failure (longer then 1 sec.), TAC-404 stops all air conditioneroperations and after 10 sec. if the failure continues, the POWER led flashes.When communication recovers, all air conditioner operations recover using the Pressure ReleaseRoutine.If the software version is V1.51 or higher and the A/C is programmed to 'COOLING ONLY',then the TAC-404 will enter to 5 minutes delay.

System Indicator Lamps:

POWER (red) - Lights up when the air conditioner is connected to the power supply andready to receive commands from the remote controller.Flashes when there is any failure with the power supply.

AIR CON (green) - Lights up when the air conditioner is ON.Flashes when de-icing takes place.

FILTER (red) - Lights up after A/C 250 hours of operation(indicates that the filter requires cleaning).

TIMER (yellow) - Lights up when air conditioner has been programmed for timer operation.

Service and Maintenance Indicator Lamps:

COMPRES. (green) - Lights up when the compressor is working.Turns Off during the first 5 minutes of a thermostat stop.Flashes when the minimum halt time (5 minutes) has passed and there is no thermostat demand.

PRESSURE (red) - Lights up when there is a Low Pressure problem in the cooling system.Flashes when there is a High Pressure problem in the cooling system.

IMPEDANCE (red) - Lights up when there is a problem with the ignition/impedance.

g) Mode Select,h) Fan Speed,i) Sweep (that appear also on models without sweep - due to factory set),j) Energy Level (not in use for TAC-404 A/C models - only in ANC, TAC-400 models).

3) When a given Section is selected for programming, the Section Title turns to reverse video(R/V) and the frame around the currently selected Symbol blinks, enabling selection changewithin this Section.

4) Any Mode, Fan Speed, Sweep or Energy Level selected Symbol appears with a solid frame.

5) At any given time only one Symbol frame can blink.

6) The R/C transmits a Send command, after releasing the button, on each of the followingoccasions:∑ After pressing On/Off button.∑ After pressing Select button, in On Mode.∑ After changing Set-Point Temperature by pressing Up-Down Rocker (in Temperature

Mode).∑ After exiting Timer Programming Mode.∑ After pressing Timer Clear button for 3 sec.∑ After pressing Up/Down Rocker when acting as Start/Stop respectively, when Sweep

Section is selected.∑ After pressing Digital Clock Set to exit current time setting.∑ After pressing the Set button in Timer Programming Mode.∑ After pressing the Delay On/Off button in order to set delay time to Start/Stop.∑ Whenever a Send command is required.

7) The R/C transmits a Beacon command, on each of the following occasions:∑ Repeat Off command every 30 min. for the next 24 hours.∑ Repeat Off command every 6 hr. after the 24 hours.∑ Repeat any On command every 10 min.∑ Every 10 min. when any Timer is programmed, including Sleep.∑ Every 10 min. (5 min. for the TAC-480 R/C) if Sense Here is active.∑ When ever a Beacon command is required.∑ Not active (no Beacon) when the R/C is programmed to ATEC mode.

8) Pressing button combination that is not defined will not effect the R/C.

TAC-404

15

9) The R/C includes a temperature sensor, and displays the measured room temperature(in Off Mode and when Room Temperature button is pressed in On Mode). The temperature is updated every 30 sec. The temperature (Set Point Temp. or Room Temp.) can be displayed in one of two scales,∞C or ∞F, according to the selected R/C setup (Dip switch 4).

10) The R/C includes a Digital Clock that displays the current time (default) with the colonblinking at 1 Hz, or a programmed Time (in Timer Programming mode). The time isdisplayed in one of two formats: a) 24:00 - appears when ∞C is selected for temperature scale display.

b) 12:00 - appears when ∞F is selected for temperature scale display.

11) When the battery is low (less than 20% capacity remaining) a blinking Low Battery symbolis displayed.

Off Mode:

Off mode is defined as the situation when the A/C is Off and the R/C display is in its default Offmode: blank, except for the Digital Clock, which displays the current time, room temperaturewith the Room Symbol and indicators and the Symbol (1, 2, 3, SLEEP, DAILY) of the activeTimer period (only).The room temperature sensing and display is refreshed every 30 sec. Pressing any button(excluding the On/Off and Timer Set and Timer Clear and Room Temp. button) while in Offmode, turns On the R/C display, displaying it’s last setting and enabling the user to program thefunctions on the display (without turning the A/C on).The R/C memorizes the new setting after the Select button is pressed. The R/C returns to Offmode immediately or 10 seconds after the last button pressing (depends which buttons werepressed), unless the On/Off button has been pressed, which causes the R/C to memorize the newsetting, transmit an On Send command and remain in On Mode.The R/C transmit an Off mode beacon every 30 min. in the next 24 hours after it was turned Offto assure A/C will go Off even if there was power failure during setting the R/C to Off mode(after 24 hours, the R/C transmit an Off beacon every 6 hours).

On Mode:

On mode is defined as the situation when the R/C display is in its default On mode, displayingall Symbols and titles (excluding either Energy Level or Sweep Symbols, according the R/Csetup), with the previously selected Symbols displayed with frames: Fan speed, Selected Sweepstatus (Swing or Static, if Sweep mode set on), Energy level (if Energy mode set on), Mode,Digital Clock, Set point temperature (the Set Point Temperature display replaces the RoomTemperature and the Room Symbol disappears), and Timer indicators (of active timer periods).

TAC-404

16

On Mode contains two sub-modes:

a) Temperature Mode (default):

In Temperature mode all the symbols are displayed, and the active Symbol is framed.Pressing the Up/Down Rocker in this mode, increases (Up) or decreases (Down) the Set PointTemperature by 1∞ (∞C or ∞F according to R/C DIP switch 4 setup).

Each Set Point change causes the R/C to transmit Send command.

b) Select mode:

Pressing the Select button causes the R/C to enter Select Mode, turning the Title to R/Vsequencing the active Section, the frame around the active Symbol blinks.Pressing the On/Off button, while in On mode, causes the R/C to transmit an Off command,exiting On Mode turns the R/C to Off Mode.

On/Off Button:

Pressing the On/Off button when the R/C is in Off mode, turns the R/C to On Mode: displayingall Symbols (excluding Energy or Sweep Symbols, according to the R/C setup, and theTransmission Indicator). The previously selected Symbols are displayed with frames (defaultOn display), and the R/C transmits an On Send command (turning the A/C on).The first pressing of the On/Off button within 10 seconds after any change of the R/C setting willcause the R/C to memorize the setting and transmit an On Send command, and remain in On mode.Pressing the On/Off button when the R/C is in On mode transmits an Off Send command(turning the A/C off), and returns the display to Off mode.

Up/Down Rocker:

The rocker, mounted on the right side of the R/C, contains two directional push-buttons -Up and Down (pressing both buttons simultaneously will not affect the R/C):

In Temperature mode (default), the rocker sets the Set Point Temperature from 12∞C to 32∞C(54∞F to 90∞F).

Momentary pressing of the Up button raises the Set Point Temperature by 1∞ (°C or °F) and

transmits a Send command. Continuous pressing of this button causes the Set PointTemperature to scroll up at a rate of 4∞ (°C or °F) per sec (useful when large Set Point increase

required).Releasing the Rocker transmits a Send command.Momentary pressing of the Down button lowers the Set Point Temperature by 1∞ (°C or °F) and

transmits a Send command. Continuous pressing of this button causes the Set Point Temperatureto scroll down at a rate of 4∞ (°C or °F) per sec (useful when large Set Point decrease required).

Releasing the Rocker transmits a Send command.

TAC-404

17

In Select mode, the Rocker sequences a blinking frame around the active Symbol enabling theselection of a new active Symbol.Pressing Up scrolls the blinking frame up to the next Symbol in a cyclic manner.Pressing Down scrolls the blinking frame down to the next Symbol in a cyclic manner.

Select Button:

Pressing the Select button sequences the active Section, causing the Section Title to appear inR/V and the frame around the active Symbol in the current Section to blink.Each pressing of the Select button causes the active Section to sequence to the next Section, inthe following order: Temperature ( default ), Fan, Sweep (depending on the R/C mode setting)Energy (depending on the R/C mode setting) and Mode, in a cyclical manner.Each pressing of the Select button memorizes the current setting and causes a Send commandtransmission.The R/C returns to temperature mode 10 sec. after the last pressing of one of the Up/Down orSelect buttons, returning to the previous setting after the last Select button press.

Changing the Fan Speed:

Starting from Temperature mode, pressing the Select button turns the Fan Title to R/V,displays a blinking frame around the currently selected Fan Speed (Low, High, Turbo or Auto).Pressing the Up or Down Rocker push-button, scrolls the blinking frame of the selected Symbol.Pressing the Select button causes transmission of a Send command of the new selected FanSpeed (only if it was changed), and memorizes the updated setting. The currently selectedSymbol frame stops blinking, the Sweep or Energy title turns to R/V (according to R/C setting)and the frame around the selected Energy or frame around the Sweep Symbol begins to blink.Also, the first pressing of the On/Off button within 10 seconds after any change of the R/Csetting will cause the R/C to memorize the setting and transmit an On Send command.* Whenever the R/C is set to Dry Mode the Fan Speed shall be set to Low without option for

System General Operation Description:

This chapter is designated for the wide understanding of the system general operation (useful fornun-technical personnel). For detailed information about routines functions, see:"Routines Detailed Functional Description".

1. Operation Routines:

The TAC400 and TAC404 are using the same algorithms that enable proper operation of the Air

Condition at large envelope environmental conditions.

The Routines software controls the A/C performance.

1.1 Operating in Cool Mode:

Turning the A/C On to Cool Mode will cause the following actions:

1.1.1 Indoor Fan Motor Operation: Turning the A/C On in Cool Mode will set the Indoor

fan on at the requested Fan speed (Low, High or Turbo), as it been set on the R/C.

The Indoor Fan speed can vary according to the operator desire. When the Indoor Fan is

set to operate at Auto Speed, the Fan will operate according to the following chart:

��

��

��

� ��

Note: The Low speed entry is automatically preceded with a very short run at turbo speed.

In Auto setting - the fan motor speed depends on the room temperature as measured bythe TH-1 thermistor or derived from the Beacon signal (as received from the R/C).TheIndoor Fan motor switch to lower speeds without any delay based on the TH-1, butonce set, can not be increased for the 2 min. delay time (This delay is cancelled when themanual setting is used).

1.1.2 The A/C will perform a pressure release routine (PRR) where the control will activate

and deactivate the 4 Way-Valve. The PRR takes up to 10 Sec.

Then the A/C turns the compressor on.

TAC-404

26

1.1.3 Compressor – The Condensing unit begin to operate after the PRR ended.

Note: The Condensing unit operates for at least 3min., even if the room temperature is

satisfactory after less than 3 min., to prevent short operation cycles.

1.1.4 Outdoor Fan Motor operation – The Outdoor Fan starts to operate in medium speed

after the PRR ended for a minimum time of about 2 min. after then the Outdoor Fan

motor speed will vary according to the condenser (outdoor) coil temperature

(as measured by TH-3 sensor).

Note: 1. Since most TADIRAN A/C’s are 3 speed Outdoor Fan Motor – High, Medium &

Low, it is most important to make sure that the Fan is wired correctly.

2. The Out Door Fan speed varies in accordance with the outdoor coil temperature:

when the temperature rises the Fan will increase its speed and vise-versa.

Each speed change is executed no less then 2 min. after the last change.

3. Night state – whenever the Electronic Control senses low ambient (especially at

night), it reduces the fan speed to reduce noise level.

1.1.5 Temperature brake: When the Electronic Control senses that the room temperature is

satisfactory – reached the selected/desired Set Point temperature - via the TH-1 sensor or

the Beacon signal (using the Auto Sense sensor that located on the R/C), its stops the

A/C condensing unit for minimum time brake of 5min., but not more then 15min.

At that time, the Indoor Fan Motor continues working. During the Temperature brake,

the compressor (COMPRES) indicator turns Off, at the end of the first 5 min., and then

it begins to flash, until the Electronic Control sense temperature demand (via TH-1 or

Auto-Sense sensor) or the 15min., max time brake is up.

Note : 1. If there was no temperature demand at the end of the maximum time brake the unit

will turn on for a period of at least 3min. (to ventilate the room air).

2. During temperature brake, any change of operation mode that as been made, by the

operator via the R/C, will cause the A/C to perform Pressure Release Routine (PRR)

and to return to work in the new operation mode requested.

3. During the first 5min., of the temperature brake, manual changing (by R/C) of the Set

Point temperature, will (can) effect the A/C brake before the 5 min. time is up, so the

A/C can be switched to On before the minimal time brake (5 min.), using the PRR.

TAC-404

27

1.1.6 Sleep Routine – The Electronic Control enables the user to operate an automatic routine

that changes the desired temperature. This routine as been designed to enable the user to

increase the Set Point while sleeping when the body temperature decreases.

This routine works as described in the 'SLEEP ROUTINE' for Cool Mode & Dry Mode.

Note: At the end of sleep function the A/C return its original Set Point and do not stop the A/C operation.

1.1.7 Special functions:

Indoor Ice prevention – whenever the Electronic Control senses ice accumulation on

the evaporator (indoor) heat exchanger, it runs a melting procedure. The ice detection

is based on the TH-2 temperature. The Electronic Control turns the Outdoor Fan Motor

Off, causing the system to rise the evaporator temperature (and melt the accumulated

ice). The Outdoor Fan Motor is halted for (maximum of) 90 sec. or until the indoor coil

temperature raise again.

Low Pressure – whenever the Electronic Control senses low capacity of the A/C (based

on an insufficient temperature differential (TH-1)-(TH-2) due to lack of gas in the

system.), it stops the A/C operation with the POWER indicator flashes and the

PRESSURE indicator will light (this combination signal Low Pressure).

Over (High) Pressure – Whenever the control senses High Pressure (Over Pressure -

OVP) on the condensing unit (by means of TH-3 temperature), it stops the A/C with

the POWER & PRESSURE indicators flashing (this combination signal High Pressure).

Recovery from the OVP fault is done by sending Off to system and re-entry to On by

mean of TAC-490 R/C or 3-position slide switch. When the recovery done by the

3-position slide switch, all flags, LEDs etc. are reset. When the recovery done by the

R/C, it cancel the POWER LED flash, but the PRESSURE fault LED remain lit.

Note: In order to perform an Over Pressure routine, the condensing temperature sensor

(TH-3) must be connected else the A/C will drive the outdoor fan motor constantly at

high speed.

Night State Routine – In order to reduce outdoor unit noise, the control changes the

outdoor fan motor speed to low when the local ambient temperature enables it.

TAC-404

28

1.2 Operating in Heat Mode:

Turning the A/C On to Heat Mode will cause the following actions:

General description:

The A/C is design for operation in Heat Mode to maintain the room temperature between the Set

Point and Set Point - 1°C (Set Point minus one Celsius degree).

In order to do so, the A/C change the gas circulation direction, so the evaporator will be hot and

the condensing unit will be cool.

Reasons why the A/C stop working (except reaching desired Set Point - temperature brake):

∑ If the condensing unit is blocked with ICE, then the A/C will perform a De-Ice routine.

∑ When the unit does not get a satisfactory efficiency - low Heating capacity (based on an

insufficient temperature differential (TH-2)-(TH-1) due to lack of gas in the system.), it

stops the A/C operation and will indicate unit failure.

1.2.1 Indoor Fan Motor - Turning the A/C On in Heat Mode will set the Indoor fan on at the

following manner:

∑ The Fan will turn On to the selected speed after 10-20sec., or when the Indoor coil

temperature reaches the temperature of 45°C/113°F. The Indoor Fan Motor speed

can varies according to the operator desire.

∑ When the Indoor Fan Motor is set to operate at Auto Speed the Fan will operate

according to the following chart:

1.2.2

��

��

��

� ��

TAC-404

29

Note: In Auto setting - the fan motor speed depends on the room temperature as

measured by the TH-1 thermistor or derived from the Beacon signal (as received from the

R/C). The Indoor Fan motor switch to lower speeds without any delay based on the TH-

1, but once set, can not be increased for the 2 min. delay time (This delay is cancelled

when the manual setting is used).

1.2.3 The A/C will perform a pressure release routine (PRR), where the control will activate

and deactivate the 4 Way Valve. The PRR takes up to 10 Sec.

The PRR is used to discharge the system pressure build during compressor run. Failure

to do so, may trip the compressor to over-load (protection) during the start-up trial

(only if the start-up happens less than 5 minutes after the last compressor run).

This routine is used only for the first entry to the Heat mode or upon power return

following a power brake (Quick restart trial in Heat Pump models). Switching between

modes require this routine each time the mode is re-entered.

Then the A/C turns the compressor on.

1.2.4 Compressor – The Condensing unit begin to operate after the PRR ended.

Note: The Condensing unit operates for at least 3min., even if the room temperature is

satisfactory. This cycle is for preventing short operation cycle of the A/C.

1.2.5 Outdoor Fan Motor operation – The Outdoor Fan Motor starts to operate in medium

speed after the PRR ended for a minimum time of about 2 min. Afterwards, the Outdoor

Fan Motor speed will vary according to the indoor coil temperature (by means of the

TH-2 temperature).

Note: 1. Since most TADIRAN A/C’s are 3 speed Outdoor Fan Motor– High, Medium &

Low, it is most important to make sure that the Fan Motor is wired correctly.

2. The Outdoor Fan Motor speed varies according to the indoor coil temperature

when the temperature rises the Fan will decrease its speed and vise-versa.

Each speed change is executed no less then 2 min. after the last change.

3. If there is no demand for heating, the unit will not start!

For e.g., if the room temperature is 20°C/68°F and the Set Point is 16°C/61°F.

TAC-404

30

1.2.6 Temperature brake: When the Electronic Control senses that the room temperature is

satisfactory – reached the selected/desired Set Point temperature - via the TH-1 sensor or

the Beacon signal, using the Auto Sense sensor (located on the R/C), its stops the A/C

condensing unit for minimum time brake of 5min., but not more then 15min.

At the same time, the Indoor Fan, Outdoor Fan and the compressor turns Off but the

4way valve remain On. During the Temperature brake the Compressor indicator turns

Off after 5 min., and if there is no temperature demand, it begins to flash until the control

sense temperature reaches Set Point - 1°C/2°F (Set Point minus one Celsius degree or

minus two Fahrenheit degree), via TH-1 or Beacon signal (Auto-Sense sensor), or the

15min., max time brake is up.

Note : 1. If there was no temperature demand at the end of the maximum time brake the unit

will turn on for a period of at least 3min. (to ventilate the room air).

2. During temperature brake, any change of operation mode, via the R/C, will cause

the A/C to perform Pressure Release Routine and to return to work in the new

operation mode requested.

3. During the first 5min., of the temperature brake, changing of Set Point will effect

the A/C brake before the 5 min. time is up.

4. When the A/C is high wall type, the Electronic Control compensate the location of

return air sensor by adding 6°C/11°F to the measured temperature.

5. When turning the A/C Off in Heat mode, the Reverse Valve remains On for

additional 2 min. (this prevent the unit self pressure release noise).

1.2.7 Sleep Routine – The control enables the user to operate an automatic routine that

changes the desired temperature. This routine as been designed to enable the user to

decrease the Set Point when the body temperature decreases.

This routine works as described in the 'SLEEP ROUTINE' for Heat Mode.

TAC-404

31

1.3 Operating in Dry Mode

Dry mode is basically a version of Cool Mode but with indoor fan motor working at low speed

only. The idea behind it is to reduce maximal humidity by compromising the efficiency of the

A/C. The system operate at same manner as in Cool mode.

Note: When there is temperature brake in the Dry mode, the indoor fan motor is stopped!

1.4 Operating in Auto Mode:

1.4.1 Setting the A/C, via the R/C, to operate in Auto Mode causes the A/C to select

automatically its operation mode. The control will decide its operation mode in

accordance with the following table (see also 'CONDITIONING ROUTINE'):

Operation

Condition

Cool Heat

Last operation Cool, Dry, Fan or TH-1>SP+1°C/2°F On Off

Last operation Heat or TH-1<SP-1°C/2°F Off On

1.4.2 Setting the A/C to Auto Mode via the 3-position slide switch, will create the same

function as it was set by the R/C, but with a default Set Point temperature of 22°C/72°F.

Indoor fan motor will work in Auto and all timer functions will be disabled.

1.5 Power Fail protection:

TADIRAN control is programmed to protect the A/C condenser against many types of power

failures. In those cases the A/C operation will be stopped, until the power will stabilize and then

the A/C will be turned On again to its last operation setting.

∑ “Short” Power Failure – When the line power fails for less then 20mSec., the Electronic

Control will ignore the power interference and will continue proper operation of the A/C.

∑ “Long” Power Failure – When the power fails for more then 20mSec., the A/C will return to

work 20 Sec. after the recovery of the power.

TAC-404

32

∑ Line Low Voltage Failure (Protection) – The control is programmed to stop all A/C

operation each time it senses Low line voltage (different values for Rotary compressors or

Reciprocating & Scroll compressors, as defined by DIP switch 2). The Electronic Control

will recover to its normal operation when it will sense a 20 Sec. of continuous normal line

voltage. If the power failure continue, the Electronic Control stops all A/C operation with

the indication of POWER & IMPEDANCE indicators flashing and the COMPRES indicator

lit.

∑ Start-Up Power Failure – During compressor start-up, the Electronic Control tests the line

power in order to prevent the power to fail under the compressor manufacturer

specifications.

When the line power falls under the compressor allowed limits, the Electronic Control will

stop the A/C operation for 20Sec., and will retry to start (restart) the unit again. If the A/C

fails to restart 5 times in sequence, the A/C will stop immediately.

Recovery from the Power failure is done by sending Off command to the unit and re-entry to

On (by mean of the R/C or the 3-position slide switch).

∑ Line Over Voltage Failure (Protection) – The control is programmed to stop all A/C

operation each time it senses High line voltage (different values for Rotary compressors or

Reciprocating compressors, as defined by DIP switch 2).

The Electronic Control stops all A/C operation with the indication of POWER indicator

flash and the COMPRES & IMPEDANCE indicators lit.

1.5.1 Special functions:

∑ Filter Clean Indicator - A FILTER clean indicator is placed on each display. The indicator

lights after 250 hours of A/C operation, to alert the user that the filter(s) require cleaning.

After cleaning the filter(s), in order to clear (set off) the FITER indicator, the user should set

the 3-position slide switch (on the display) to Off for 2-3 sec. (at least).

∑ Outdoor De-Ice – whenever the Electronic Control senses ice accumulation on the

condensing (outdoor) heat exchanger unit, it runs melting procedure.

TAC-404

33

∑ The procedure works as follow:

One. The indoor fan motor stops,

Two. The A/C stops all Heat Mode functions and switch, via PRR, to Cool mode

where the 4 way valve turns the gas cycle as in the Cool mode, so now the

hot condenser (outdoor) coil begin melting the ice. This process will continue

until the condenser coil temperature rise above 20_C/68°F or 10min. (at the

most) after the process begins.

Three. At the end of the process, the unit recovers to the Heat mode operation,

again via the PRR.

Four. The Defrost process is in cycles, when each cycle period depends on the

condensing (outdoor) unit coil temperature.

The detection process counts for time temperature development.

The detection process start when TH-3 temperature falls below +3°C/37°F.

Then, the Electronic Control start counting time.

If the temperature rise back to the +3°C/37°F, before the ice has been

detected, the De-Ice process is canceled.

∑ Low-Pressure – whenever the Electronic Control senses low Heating capacity of the A/C

(based on an insufficient temperature differential (TH-2)-(TH-1) due to lack of gas in the

system), it stops the A/C operation and will indicate unit failure.

∑ Over (High) Pressure – Whenever the control senses High Pressure (Over Pressure - OVP)

on the indoor unit (by means of TH-2 temperature), it stops the A/C with the POWER &

PRESSURE indicators flashing (this combination signal High Pressure).

Recovery from the OVP fault is done by sending Off to system and re-entry to On by mean

of TAC-490 R/C or 3-position slide switch. When the recovery done by the 3-position slide

switch, all flags, LEDs etc. are reset. When the recovery done by the R/C, it cancel the

POWER LED flash, but the PRESSURE fault LED remain lit.

2 The Electronic Control structure:

TADIRAN Electronic Control is based on two main parts:

Main unit named TAC-444 and Display Assy named TAC-460XX when the XX stands for the

type of A/C its fits to, for example: TAC-460GF means that the display fits to all GFL-S A/C

family.

The main unit is same unit for all type of A/C whether its ANL, TNL or GFL.

The display unit contains the operation logic that runs the A/C in all operation Mode and via all

operation procedures.

2.1 Communication:

2.1.1 The main unit TAC-444 and the Display Assy TAC-460. The control uses

communication between these two unit when the main unit supply the data coming up

from the A/C, the Display Assy process the data and send operation command to be

executed by the main TAC-444 unit.

2.1.2 Data transferred from the Main unit (TAC-444) to the Display Assy (TAC-460):

2.1.2.1 Temperature - the Main unit transfer the temperature measured by the thermistors

located at the Return-Air (TH-1), Indoor coil (TH-2) and Out door coil (TH-3).

2.1.2.2 Power – The Main unit measures the power line voltage and transmits it to the Display

Assy.

2.1.2.3 Operation feedback – the Main unit transmit operation feedback to the Display Assy,

assuring what are the units that are loaded.

2.1.3 Command transferred from the Display Assy (TAC-460) to the Main unit (TAC-444).

The Display Assy transfers command to the main unit such as:

Operate the A/C accordingly Set the compressor On or turn it Off, set the

Indoor fan motor speed to one of its operation speed or turn it Off, set the Outdoor fan

motor speed to one of its operation speed or turn it Off & 4 way valve set On or Off.

2.1.4 Communication failure: In case of communication failure the following action will take place:

- All A/C loads (fans, compressor & 4 way valve) will turn Off.

- The Power indicator will flash – no other indicator will light.

Routines Detailed Functional Description:

(This section designated for the detailed understanding of the software routines operation).

COOL MODE:

The COOL MODE consists of entry procedure the 'RUN Loop' and 'REST Loop'.

The entry procedure set (or verifies) that the compressor(s) is Off and enter the PRESSURE

RELEASE ROUTINE for 10 sec. approximately. The TAC-404 system has one compressor and

the TAC-400 (ANC models) two compressors: one small and one large.

(The ANC system may run one of the compressors or both, but the startup for two

compressors requires special procedure.)

During normal operation, the TH-1 (intake/return air) thermistor switches between the RUN and

REST loops depending on the incoming air (room) temperature.

The PRESSURE RELEASE ROUTINE is not used during these switching cycles (it is used only

upon entry to the COOL MODE for the first time).

RUN LOOP:

(The entry to the RUN Loop for the ANC is made via special routine that starts both

compressors sequentially.) After switched to run, the 5 and 10 minute delays are triggered.

The 5 minutes delay is used as the minimum compressor/s run period, the 10 minute delay is

used to skip the LOW PRESSURE ROUTINE test for the first 10 minutes of compressor run.

REST LOOP:

When the room temperature as measured by the TH-1 (or received by the Beacon signal) reach

the desired Set-Point temperature (and the corresponding offsets), the RUN Loop is exited and

the system switched to REST Loop (Thermostat Stop/Temperature Brake).

The REST Loop is entered after a 5 min. and 15 min. delays are triggered. The 5 min. delay is

used as the 'minimum compressor rest period', while the 15 min. delay is the 'maximum

compressor rest period'

First, the REST Loop setting the compressor(s), reverse valve, outdoor fan motor and the

compressor (COMPRESS) LED Off. In addition, it also checks for any request to quit the cool

mode or Timer OFF demand to stop the system.

TAC-404

50

The 'INDOOR FAN ROUTINE' - sets the required indoor fan motor speed as per operator

manual setting or automatic speed control (according to the room temperature).

After the 5 minutes of the REST Loop, the compressor LED is set to flash to indicate that theREST Loop is controlled by the room temperature (TH-1 or Beacon signal and theircorresponding offsets).

If 15 minutes (the 'maximum compressor rest period') is reached, the system is switched to the

RUN Loop - this in spite the fact that the room temperature did not rise (above the desired Set

Point) to trigger the system to run. In addition, before the RUN Loop is entered, a

CONDITIONING ROUTINE is scanned. This routine is activated on Auto Mode where the

system may switch automatically between the Cool and Heat modes.

PRESSURE RELEASE ROUTINE (COOL MODE):

The 'PRESSURE RELEASE ROUTINE' is used to discharge the system pressure build during

compressor run. Failure to do so, may trip the compressor to over-load (protection) during the

start-up trial (only if the start-up happens less than 5 minutes after the last compressor run).

This routine is scanned only for the first entry to the Cool mode or upon power return following

a power brake (Quick restart trial in Heat Pump models). Switching between modes require this

routine each time the mode is re-entered.

This routine is not active during normal compressor RUN-REST cycles (Loops).

The routine is used also if during the 'minimum compressor rest period', there is a manual request

(by mean of R/C) to change the desired Set Point and/or operation mode (to Heat). Then, if

necessary, the re-entry will be via the 'PRESSURE RELEASE ROUTINE'.

The routine is divided into two parts where the Reverse Valve is set to On and Off.

During this routine:

∑ the compressor/s set/kept Off;

∑ the 'INDOOR FAN ROUTINE' scanned for IF (indoor fan motor) speed;

∑ the outdoor fan motor set/kept in High speed;

TAC-404

51

∑ The indicators:

Æ POWER LED On;

Æ AIR CON LED On;

Æ FILTER LED On or Off (according to 'FILTER CHECK ROUTINE');

Æ COMPRESS LED Off;

Æ IMPEDANCE LED per Power Failure Routines;

Æ PRESSURE LED per 'PRESSURE FAULT ROUTINE' and, OVP or LOP Routine

Upon completion, this routine is exited entirely.

Important Note: due to all the above mentioned, in COOLING ONLY A/C models with

software version below V1.51 you must connect the Reverse Valve (solenoid) - yellow wire

(station number 3 on the indoor and outdoor terminal boards).

For COOLING ONLY A/C models (when TAC-460 DIP Switch no. 3 is set to On) with the

TAC-460 software version starting from V1.51, this routine is skipped and a 5 min. time delay

is used between restarts.

FULL COMPRESSOR START-UP ROUTINE (COOL MODE):

This routine controls sequential start-up for both compressors in TAC-400 (ANC) only.

First, the Small compressor is turned On, and after 2 sec. delay, the Large compressor is

started. During this time the indoor fan speed is controlled by the 'INDOOR FAN ROUTINE'

while the outdoor fan speed is controlled by the 'NIGHT STATE ROUTINE'.

Before exit, the Compressor LED (COMPRES) is switched to On (continuously) indicating that

both compressors are running.

CHANGE MODE ROUTINE (COOL MODE):

This routine checks if manual or Timer OFF function are set. This routine may branch the

system:

to Off or;

∑ to other than the current Cool mode;

The manual demand is entered by the R/C. When the operator change the operating mode, the

system leave the running mode and enter the new mode.

TAC-404

52

If Timer functions are active, this routine monitor the Timer flag and if the flag is Set (i.e. Timer

OFF is demanded), the system is turned Off with all the last settings memorized including,

MODE, FAN, SET-POINT TEMPERATURE etc.

When no change is required, this routine is skipped.

If a new mode or system Off is required, all the current system delays of the Cool cycle are

cleared (as well as the Auto Energy settings in the ANC system).

INDOOR FAN ROUTINE (COOL MODE):

The routine controls the indoor fan motor speed to one of the three speeds: Low, High or Turbo.

The Low speed entry is automatically preceded with 0.5 second run at turbo speed.

The routine has two branches:

∑ Manual setting - the fan motor speed is set by the operator (by means of the TAC-490 R/C).

∑ Auto setting - the fan motor speed depends on the room temperature (with the correspondingoffsets) as measured by the TH-1 thermistor or derived from the Beacon signal (using thetemperature values as received from the R/C).The routine switch to lower speeds without any delay based on the TH-1 (and the offsets),but once set, can not be increased for the 2 min. delay time (This delay is cancelled when themanual setting is used).

1. If TH-1 is higher than the SP by (not more than) 1.5∞C, the speed is Low.

2. If TH-1 is higher than the SP by more than 1.5∞C to 3∞C, the speed is High.

3. If TH-1 is higher than the SP by 3∞C or more, the speed is Turbo.

(SP = Set Point = desired temperature.)

COMPRESSOR OFF ROUTINE (COOL MODE):

This routine sets and keeps the compressor(s) Off in the REST Loop (Thermostat Stop).For the first 5 min., the 'minimum compressor rest period', the following settings and routinesare scanned:

∑ Compressor(s) set and kept Off;

∑ Reverse Valve kept Off;

∑ Outdoor fan motor set and kept Off;

∑ 'CHANGE MODE ROUTINE' scanned for any request to quit the Cool mode or Timer Off

demand to stop the system;

TAC-404

53

∑ 'INDOOR FAN ROUTINE' - to set the required fan motor speed as per operator manual

setting or automatic speed control (according to the room temperature), and;

∑ the compressor LED (COMPRES) is set to Off.

After the 5 minutes, control of the compressor LED is set to flash as controlled in the REST

Loop afterwards.

INDOOR ANTI-ICE ROUTINE (COOL MODE):

The 'ANTI-ICE ROUTINE' checks for ice accumulation on the evaporator (indoor) heat

exchanger and run melting procedure if necessary.

The ice detection is based on the TH-2 temperature. When TH-2 sense below -1°C/30°F (minus

one Celsius/thirty Fahrenheit) temperature, the De-Ice Process is initiated; triggering the 90 sec.

delay (maximum outdoor fan motor halt time) and turn Off the outdoor fan motor (the outdoor

fan motor state is memorized).

The halt of the outdoor fan motor cause the system to rise the evaporator temperature (and melt

the accumulated ice).

Next scan of this routine is when the outdoor fan is Off. Here the TH-2 temperature is checked

for TH-2 > +5°C/41°F condition. The outdoor fan motor continues to be halted as long as the

condition is not met or the halt time is less than the 90 sec.; otherwise, the outdoor fan motor is

recovered (set to On).

NIGHT STATE ROUTINE (COOL MODE):

The 'NIGHT STATE ROUTINE' switches the outdoor fan motor to its Low speed during lower

ambient temperatures as expected during nighttime.

The routine is skipped if the outdoor fan is Off (during De-Ice Process - see 'INDOOR ANTI-

ICE ROUTINE') or the TH-3 is disconnected. In the last case, the outdoor fan motor is set to

High speed unconditionally.

During normal operation, the outdoor fan motor is switched according to TH-3 temperature.

TAC-404

54

Controlling Outdoor Fan Motor (COOL MODE):

TAC-404 supports 3 outdoor fan motor speeds.

∑ After air conditioner startup, the outdoor fan motor speed is always medium.

∑ Each speed change is executed no less then 2 minutes after the last change.

LOW PRESSURE (LOP) ROUTINE (COOL MODE):

This routine detects "Low Pressure" in the evaporator (indoor), based on an insufficient

temperature differential (TH-1)-(TH-2) due to lack of gas in the system.

The routine is skipped for the first 10 min. from the RUN Loop entry.

The differential threshold is depended on the number and size of compressors active during the

routine scan. The following limits shall turn the Low Pressure flag to '1' (the temperature scale is

in °C/°F degrees):

If both compressors running or TAC-404 system (TH-1)-(TH-2) < 6°C/11°F

If Large (2/3) compressor run (TAC-400 system only) (TH-1)-(TH-2) < 4°C/7°F

If Small (1/3) compressor run (TAC-400 system only) (TH-1)-(TH-2) < 2°C/4°F

This routine is used for Low cooling capacity detection (and protection).

If none of these conditions is met, the Pressure LED is set to Off.

The LOP flag is scanned in RUN Loop and if set for first time, the REST Loop is entered.

The LOP flag remains set.

Pressure Fault Conditions:

If after the REST Loop, re-entry of the RUN Loop and the 10 min. run, the LOP conditions

developed again, the Pressure Fault flag is set (in addition to the LOP flag). This condition shall

switch the system to Stop.

The Low Pressure Fault condition is indicated by:

∑ PRESSURE LED is set to On;

∑ POWER LED is flashing and;

∑ AIR CON LED is set to Off.

TAC-404

55

Recovery from the Low Pressure fault is done by sending Off to system and re-entry to On (by

mean of TAC-490 R/C or 3-position slide switch). When the recovery is done by the R/C, it

cancels the POWER LED flash and the system shall run again, but the PRESSURE Fault LED

shall stay On (indicating that a Pressure fault occurred).

When the recovery done by the 3-position slide switch, it will reset all LED's (including

switching off PRESSURE LED).

OVER PRESSURE (OVP) ROUTINE (COOL MODE):

The 'OVER PRESSURE ROUTINE' checks for pressure rise by means of TH-3 temperature. If

Over Pressure conditions met, the OVP flag is set and the system is switched to Rest Loop.

If the Over Pressure condition repeats, Pressure fault flag is set and the system operation is

halted and PRESSURE LED (maintenance indicator) is set to On. The last indicates a Pressure

fault condition.

This routine is skipped when TH-3 is disconnected.

The High Pressure is detected when:

∑ (TH-3) > 65°C/149°F (for rotary compressor: TAC-460 DIP Switch no. 2 is On) or;

∑ (TH-3) > 75°C/167°F (for reciprocating and scroll compressors: TAC-460 DIP Switch no. 2

is On). Then;

For the first time the Over Pressure detected, the Pressure fault LED and the OVP timer are Off.

This results in triggering the OVP timer and setting the OVP flag = 1. The last one is checked in

the RUN Loop and switches the system to the REST Loop with the COMPRES LED Off (as in

Thermostat Stop - so the user will see it as a temperature brake);

After the system re-enter the RUN Loop, the OVP flag is reset and if the system do not develop

the Over Pressure again within 3 min. (of running), the OVP timer and the Pressure fault LED

are reset, thus, the initial conditions restored;

If the Over Pressure condition is developed again within 3 min. (from the previous/first OVP

detection (after the minimum rest completion), the Pressure fault flag is set. The last flag is

checked in the RUN Loop and switch the system to Halt via the 'PRESSURE FAULT

ROUTINE' where the Pressure fault LED is set to On;

TAC-404

56

The Over Pressure Fault condition is indicated by:

∑ PRESSURE LED is flashing;



Recovery from the Over Pressure fault is done by sending Off to system and re-entry to On by

mean of TAC-490 R/C or 3-position slide switch. When the recovery done by the 3-position

slide switch, all flags, LEDs etc. are reset. When the recovery done by the R/C, it cancel the

POWER LED flash, but the PRESSURE fault LED remain lit (indicating that a Pressure fault

occurred).

Note: Switching to other mode of operation will reset all flags, LEDs and timers in the

'OVER PRESSURE ROUTINE'.

SLEEP ROUTINE (COOL MODE):

The 'SLEEP ROUTINE' is automatically initiated by the (R/C Sleep) TIMER STOP function. It

allow temperature Set Point to be offset with time. This results in longer compressor Off

intervals (and power saving).

CONDITIONING ROUTINE - GENERAL (AUTO HEAT/COOL MODE):

A mode in which the A/C switches automatically the HEAT and COOL (and vice versa)

operations. The selection is based on the previous status and room temperature variations.

This AUTO mode can be selected manually either by the R/C or the 3-position slide switch on

the TAC-460 Display Assy.

On the entry to the AUTO mode, the initial decision to run the HEAT or COOL shall be based

on the last, prior to the AUTO mode entry, operation mode;

If within the last hour, the last operation mode was COOL, DRY or FAN ONLY, the

Auto shall run COOL, or;

If within the last hour, the last operation mode was HEAT, the Auto shall run HEAT,

or;

TAC-404

57

If no run last at last hour, prior to the Auto selection, the initial selection between the COOL

and HEAT run shall be made automatically as follows:

∑ If (TH-1) > (SP + 1°C/2°F) then set to COOL mode;

∑ If (TH-1) < (SP - 1°C/2°F) then set to HEAT mode;

∑ If (SP - 1°C/2°F) £ (TH-1) £ (SP + 1°C/2°F) then restore the last, COOL or HEAT, mode. If

the last mode was set to COOL, DRY or FAN ONLY, the system is switched to COOL mode.

If set from the R/C, all other present R/C parameters are executed in parallel (Temperature Set

Point, Fan Motor speed, Timer etc.)

If set by the 3-position slide switch, the initial conditions are activated as follow:

∑ FAN: Auto.

∑ TIMERs: Reset.

∑ S.P. Temperature: 22°C/72°F.

AUTO-ENERGY ROUTINE (COOL MODE):

This routine automatically adjust the Energy drived (only) in the TAC-400 (ANC) system, by

selecting which of the compressors or both to be run.

The selection depends on the current indoor fan motor speed and compressors that in run and

the evaporating temperature in Cool mode (or condensing temperature in Heat mode).

TAC-404

58

HEAT MODE:

The HEAT MODE consists of entry procedure the 'RUN Loop' and 'REST Loop'.

The entry procedure set (or verifies) that the compressors are Off and enter the PRESSURE

RELEASE ROUTINE for 10 sec. approximately. The TAC-404 system has one compressor and

the TAC-400 (ANC models) two compressors: one small and one large.

(The ANC system may run one of the compressors or both, but the startup for two

compressors requires special procedure.)

During normal operation, the TH-1 (intake/return air) thermistor switches between the RUN and

REST loops depending on the incoming air (room) temperature.

The PRESSURE RELEASE ROUTINE is not used during these switching cycles (it is used only

upon entry to the HEAT MODE for the first time).

RUN LOOP:

(The entry to the RUN Loop for the ANC is made via special routine that starts both

compressors sequentially. After switched to run, the 5 and 10 minute as well as 10 and 20 sec.

delays are triggered.

The 5 minutes delay is used as the minimum compressor(s) run period, the 10 minute delay is

used to skip the LOW PRESSURE ROUTINE test for the first 10 minutes of compressor run.

The 10 and 20 sec. delays are used to delay the indoor fan start for the reciprocating or rotary

compressors respectively. This avoids blow of chill (cold) air before the evaporator (indoor) coil

temperature has been reached to 45°C/113°F (see also: 'INDOOR FAN ROUTINE').

REST LOOP:

When the room temperature as measured by the TH-1 (or received by the Beacon signal) reach

the Set-Point temperature (and the corresponding offsets), the RUN Loop is exited and the

system switched to REST Loop (Thermostat Stop/Temperature Brake).

The REST Loop is entered after 15 sec., 5 & 15 min. delays are triggered. The 15 sec. is used to

delay the indoor fan motor stop (so the heating capacity is still supplied until the indoor coil

temperature drops). The 5 min. delay is used as the 'minimum compressor rest period', while the

15 min. delay is the 'maximum compressor rest period'.

TAC-404

59

First the REST Loop is setting the compressor(s), outdoor fan motor and the compressor

(COMPRES) LED Off. The Reverse Valve is kept On as well as the indoor fan motor (see:

'INDOOR FAN ROUTINE'). In addition, it also checks for any request to quit the Heat mode

or Timer OFF demand to stop the system. The 'INDOOR FAN ROUTINE' sets the required

indoor fan speed as per operator manual setting or automatic speed control (according to the

room temperature).

Then, after the 15 sec., the above functions continue with the indoor fan Off for the next 5 min.

(the 'minimum compressor rest period').

After the 5 minutes of the REST Loop, the compressor LED is set to flash to indicate that the

REST Loop is controlled by the room temperature (TH-1 or Beacon signal and their

corresponding offsets).

If 15 minutes (the 'maximum compressor rest period') is reached, the system is switched to the

RUN Loop - this in spite the fact that the room temperature did not fall rise (below the desired

Set Point) to trigger the system to run. In addition, before the RUN Loop is entered, a

CONDITIONING ROUTINE is scanned. This routine is activated on Auto Mode where the

system may switch automatically between the Cool and Heat modes.

PRESSURE RELEASE ROUTINE (HEAT MODE):

The 'PRESSURE RELEASE ROUTINE' is used to discharge the system pressure build during

compressor run. Failure to do so, may trip the compressor to over-load (protection) during the

start-up trial (only if the start-up happens less than 5 minutes after the last compressor run).

This routine is scanned only for the first entry to the Heat mode or upon power return following

a power brake (Quick restart trial in Heat Pump models). Switching between modes require this

routine each time the mode is re-entered.

This routine is not active during normal compressor RUN-REST cycles (Loops).

The routine is used also if during the 'minimum compressor rest period', there is a manual request

(by mean of R/C) to change the desired Set Point and/or operation mode (to Cool). Then, if

necessary, the re-entry will be via the 'PRESSURE RELEASE ROUTINE'.

The routine is divided into two parts where the Reverse Valve is set to Off and On.

During this routine:

TAC-404

60

∑ the compressor/s set/kept Off;

∑ the indoor fan motor is Off;

∑ the outdoor fan motor set/kept in High speed;

∑ The indicators:

Æ POWER LED On;

Æ AIR CON LED On;

Æ FILTER LED On or Off (according to 'FILTER CHECK ROUTINE');

Æ COMPRES LED Off;

Æ IMPEDANCE LED per Power Failure Routines;

Æ PRESSURE LED per 'PRESSURE FAULT ROUTINE' and, OVP or LOP Routine

Upon completion of the 10 sec. approximately, this routine is exited entirely.

FULL COMPRESSOR START-UP ROUTINE (HEAT MODE):

This routine controls sequential start-up for both compressors in TAC-400 (ANC) only.

First, the Small compressor is turned On, and after 2 sec. delay, the Large compressor is

started. During this time the indoor fan motor speed is kept Off, while the outdoor fan speed is

set to High.

CHANGE MODE ROUTINE (HEAT MODE):

This routine checks if manual or Timer OFF function are set. This routine may branch thesystem:

∑ to Off or;

∑ to other than the current Heat mode;

The manual demand is entered by the R/C. When the operator change the operating mode, a flag

for Change Mode Request is turned On. During scan of this routine, this flag is reset and if

different than the running mode has been requested, the system leaves the running mode and

enter the new mode.

If Timer functions are active, this routine monitor the Timer flag and if the flag is Set (i.e. Timer

OFF is demanded), the system is turned Off with all the last settings memorized including,

MODE, FAN, SET-POINT TEMPERATURE etc.

TAC-404

61

When no change is required, this routine is skipped.

If a new mode or system Off is required, all the current system delays of the Heat cycle are

cleared (as well as the Auto Energy settings in the ANC system).

INDOOR FAN ROUTINE (HEAT MODE):

The routine controls the indoor fan motor speed to one of the three speeds: Low, High or Turbo.

The Low speed entry is automatically preceded with 0.5 second run at turbo speed.

The routine starts with 10 sec. (for reciprocating or 20 sec for rotary type compressor) hold off

of the indoor fan motor. Unless the TH-2 temperature rises above 45°C/113°F, the indoor fan

motor shall be Off for that time.

If the 10 sec. (or 20 sec.) elapsed or the TH-2 > 45°C/113°F, whichever comes first, the indoor

fan motor shall be started and controlled by one of the two branches:

∑ Manual setting - the fan motor speed is set by the operator (by means of the TAC-490 R/C).

∑ Auto setting - the fan motor speed depends on the room temperature (with the correspondingoffsets) as measured by the TH-1 thermistor or derived from the Beacon signal (using thetemperature values as received from the R/C).

The routine switch to lower speeds without any delay based on the TH-1 (and the

corresponding offsets), but once set, can not be increased for the 2 min. delay time (This delay is

cancelled when the manual setting is used).

COMPRESSOR OFF ROUTINE (HEAT MODE):

This routine sets and keeps the compressor(s) Off in the REST Loop (Thermostat Stop).

For the first 15 sec., the indoor fan motor continues to run. Then, for the 5 min., the 'minimum

compressor rest period', the following settings and routines are scanned:

∑ compressor(s) set and kept Off;

∑ Reverse Valve kept On;

∑ outdoor fan motor set and kept Off;

∑ 'CHANGE MODE ROUTINE' scanned for any request to quit the Heat mode or Timer Off

demand to stop the system;

∑ Indoor fan motor is set and kept Off;

∑ the compressor LED (COMPRES) is set to Off.

TAC-404

62

After the 5 minutes, control of the compressor LED is set to flash as controlled in the REST

Loop afterwards.

OUTDOOR ICE CHECK ROUTINE (HEAT MODE):

In Heat mode the TH-3 thermistor sense for ice accumulation on the outdoor (condenser) heat

exchanger and run defrost procedure if necessary. The detection process counts for time

temperature development.

The detection process starts when TH-3 temperature falls below +3°C/37°F. Then, the ICE

Timer start counting time.

If the temperature rises back to the +3°C/37°F, before the ice has been detected (as described

below), the ICE Timer is cleared and the process canceled.

Ice is detected if one of the conditions is met:

a. the (TH-3) < (-8°C/18°F) and 30 minute elapsed or;

b. the (TH-3) < (-4°C/21°F) and 60 minute elapsed or;

c. the (TH-3) < (-2°C/28°F) and 120 minute elapsed or;

Upon ice detection, the DE-ICE request flag is set and when scanned in the RUN Loop, the

system is entered to the ‘DE-ICEING ROUTINE’.

OUTDOOR FAN ROUTINE (HEAT MODE):

This routine is scanned automatically during Heat mode RUN Loop within the ‘COMPRESSOR

ON ROUTINE’.

The routine try to reduce a high pressure developed in indoor unit (due to deviation in

environmental conditions). If this control by ‘OUTDOOR FAN ROUTINE’ fail, the system is

further controlled by the ‘OVER PRESSURE ROUTINE’.

The routine operation:

∑ The routine checks for high pressure in the evaporator unit by means of the TH-2 thermistor

temperature. If high pressure condition met, i.e.: TH-2 > 55°C/131°F, the outdoor fan motor

is stopped resulting in pressure drop. The outdoor fan motor halt is limited to 11 minutes.

TAC-404

63

∑ If the pressure drops (TH-2 £ 53°C/127°F), the system shall gradually recover by entering

the outdoor fan motor to Low speed for 10 minutes.

∑ If the high pressure do not drop sufficiently, despite the outdoor fan motor halt, the system

will be switched to REST Loop.

In addition, the outdoor fan motor High speed may be reduced to Low for TH-2 > 53°C/127°F

(when the system deliver enough heat).

If the Heat mode is exited, all delays are reset.

LOW PRESSURE (LOP) ROUTINE (HEAT MODE):

This routine detects "Low Pressure" in the evaporator (indoor), based on an insufficient

temperature differential (TH-2)-(TH-1) due to lack of gas in the system.

The routine is skipped for the first 10 min. from the RUN Loop entry.

The differential threshold is depended on the number and size of compressors active during the

routine scan. The following limits shall turn the Low Pressure flag to '1' (the temperature scale is

in °C/°F degrees):

If both compressors running or TAC-404 system (TH-1)-(TH-2) < 6°C/11°F

If Large (2/3) compressor run (TAC-400 system only) (TH-1)-(TH-2) < 4°C/7°F

If Small (1/3) compressor run (TAC-400 system only) (TH-1)-(TH-2) < 2°C/4°F

This routine is used for Low heating capacity detection (and protection).

If none of these conditions is met, the Pressure LED is set to Off.

The LOP flag is scanned in RUN Loop and if set for first time, the REST Loop is entered.

The LOP flag remains set.

Pressure Fault Conditions:

If after the REST Loop, re-entry of the RUN Loop and the 10 min. run the LOP conditions

developed again, the Pressure Fault flag is set (in addition to the LOP flag). This condition shall

switch the system to Stop.

TAC-404

64

The Low Pressure Fault condition is indicated by:

∑ PRESSURE LED is set to On;



Recovery from the Low Pressure fault is done by sending Off to system and re-entry to On (by

mean of TAC-490 R/C or 3-position slide switch). When the recovery is done by the R/C, it

cancels the POWER LED flash and the system shall run again, but the PRESSURE Fault LED

shall stay On (indicating that a Pressure fault occurred).

When the recovery done by the 3-position slide switch, it will reset all LED's (including

switching off PRESSURE LED).

OVER PRESSURE (OVP) ROUTINE (HEAT MODE):

The 'OVER PRESSURE ROUTINE' checks for pressure rise by means of TH-2 temperature. If

Over Pressure conditions met, the OVP flag is set and the system is switched to Rest Loop.

If the Over Pressure condition repeats, Pressure fault flag is set and the system operation is

halted and PRESSURE LED (maintenance indicator) is set to On. The last indicates a Pressure

fault condition.

The high pressure is detected when: TH-2 > 75°C/167°F.

For the first time the Over Pressure detected, the Pressure fault LED and the OVP timer are Off.

This results in triggering the OVP timer and setting the OVP flag = 1. The last one is checked in

the RUN Loop and switches the system to the REST Loop with the COMPRES LED Off (as in

Thermostat Stop - so the user will see it as a temperature brake);

After the system re-enter the RUN Loop, the OVP flag is reset and if the system do not develop

the Over Pressure again within 3 min. (of running), the OVP timer and the Pressure fault LED

are reset, thus, the initial conditions restored;

If the Over Pressure condition is developed again within 3 min. (from the previous/first OVP

detection (after the minimum rest completion), the Pressure fault flag is set. The last flag is

checked in the RUN Loop and switch the system to Halt via the 'PRESSURE FAULT

ROUTINE' where the Pressure fault LED is set to On;

TAC-404

65

The Over Pressure Fault condition is indicated by:

∑ PRESSURE LED is flashing;



Recovery from the Over Pressure fault is done by sending Off to system and re-entry to On by

mean of TAC-490 R/C or 3-position slide switch. When the recovery done by the 3-position

slide switch, all flags, LEDs etc. are reset. When the recovery done by the R/C, it cancel the

POWER LED flash, but the PRESSURE fault LED remain lit (indicating that a Pressure fault

occurred).

Note: Switching to other mode of operation will reset all flags, LEDs and timers in the

'OVER PRESSURE ROUTINE'.

SLEEP ROUTINE (HEAT MODE):

The 'SLEEP ROUTINE' is automatically initiated by the (R/C Sleep) TIMER STOP function. It

allow temperature Set Point to be offset with time. This results in longer compressor Off

intervals (and power saving).

CONDITIONING ROUTINE (Switching from the Heat to Cool Mode):

This routine applies when the Auto mode is run. See ‘CONDITIONING ROUTINE’ - General

for initial entry to Auto mode.

The routine checks if the current Heat mode should continue or the system to be switched to

Cool mode.

If the system completed its REST Loop for over 15 min. without demand for Heat run, the

‘CONDITIONING ROUTINE’ is entered. First the routine sets the indoor fan motor to Low

speed for 2 min.

If during this 2 minutes one of the conditions:

(TH-1) £ (SP + T4) for Upper Installation or;

(TH-1) < (SP + T3) for Lower Installation

is met, the system continue the Heat mode cycle. Otherwise, the routine continue the indoor fan

motor Low (speed) operation and scan the ‘CHANGE MODE ROUTINE’ for the 2 minutes.

TAC-404

66

If the 2 min. run-out, and the above conditions were not met, the Cool mode request flag is set.

Cool mode request flag cause mode change to Cool mode and reset all functions of the Heat

mode.

The A/C operation is switched to the Cool mode via the ‘PRESSURE RELEASE ROUTINE’.

If for the lower installation, after the 2 min. period the temperature stay between:

(SP + T4) > TH-1 ≥ (SP + T3)

the routine stop the indoor fan motor and check for change mode request only.

T3 T4 Installation

+5∞C +4∞C Upper

-2∞C +2∞C Lower

0∞C +3∞C Beacon

ENERGY CHANGE ROUTINE (HEAT MODE):

The routine is activated by the Energy Change flag (in TAC-400 system only) either manual

(by R/C) or by the ‘AUTO ENERGY ROUTINE’.

The routine modify the size or sets both of the compressor(s) to run:

∑ If both compressors are running, the routine immediately switch to Off one of the unwanted

compressors;

∑ If one of the compressors are running, the routine branches to stop the compressor for 2 min.

(two minutes rest loop). Then, remaining system pressure is released.

Finally, the required compressor is switched On. If both compressors to be switched to On

(Full Energy), the ‘FULL COMPRESSOR START-UP ROUTINE’ is scanned.

Note: In Heat mode, during the 2 min. rest in the ‘ENERGY CHANGE ROUTINE’, the indoor

fan motor is stopped!

TAC-404

AUTO-ENERGY ROUTINE (HEAT MODE):

This routine automatically adjust the Energy drived (only) in the TAC-400 (ANC) system, by

selecting which of the compressors or both to be run.

The selection depends on the current indoor fan motor speed and compressors that in run and

the condensing temperature in Heat mode (or evaporating temperature in Cool mode).

DE-ICE ROUTINE (HEAT MODE):

The De-Ice routine is operated in Heat mode only.

The routine is run to defrost ice accumulated on the condenser (outdoor) heat exchanger unit.

The detection is done by the ‘ICE-CHECK ROUTINE’. Upon detection of ice, the system is

forced temporarily to Cool cycle with the indoor fan motor Off.

Note: During this routine operation, the AIR CON indicator LED flash.

∑ The routine initiates with triggering the 30 and 40 sec. delay timers. During the first 30 sec.,

the compressor, the outdoor and indoor fan motors are kept Off.

The Reverse Valve remains On. This allow gradual pressure release;

∑ Next, the Reverse Valve is turned Off and for additional 10 sec. The compressor, the outdoor

fan motor, the indoor fan motor and the Reverse Valve are all kept Off. This period stabilize

the system before running into the de-icing process;

∑ After this additional 10 sec. (which is 40 sec. from the routine entry), the system enter the

de-icing process by running the compressor in cooling cycle while the indoor and outdoor fan

motors are stopped. This results in heating the condenser unit (relatively fast) and thus

melting the accumulated ice.

∑ The process terminates either when the TH-3 temperature rise above +20°C/68°F or, after

run-out of the 10 min. period - whichever comes first.

TAC-404

68

DRY MODE ROUTINE:

The Dry mode operation is similar to the Cool mode with the some exceptions such as:

∑ The indoor fan motor speed is set to Low unconditionally.

∑ Dry mode ‘COMPRESSOR OFF ROUTINE’ (the indoor fan motor is set to Off

unconditionally).

FILTER CHECK ROUTINE:

This routine consists of 250-hour timer and an indication (FILTER) LED.

When the counter completes the 250 hours, the FILTER red LED (on the TAC-460 Display

Assy board) is set to lit. To turn the led Off and initialize the counter, the main 3-position slider

switch should be set to OFF for 2-3 sec. (at least) and then to REMOTE (RMOT).

The current accumulated time is saved in the systems EEPROM.

TH-1 & TH-2 Thermistors Check (Disconnection or Short Circuit):

Thermistors are checked for disconnection or short circuit during the first 3 minutes of each

compressor operation start and during every thermostat stop.

The malfunction (disconnection or short circuit) must appear continuously for at least 1 minute

in order to be identified by the TAC-404.

After the first 3 minutes of compressor operation, if TAC-404 finds any problems with the

TH-1 & TH-2 thermistors, the air conditioner continues to operate with the following default

values:

Mode / Thermistor TH-1 TH-2Cooling Mode 30∞C 10∞CHeating Mode 10∞C 40∞C

If TAC-404 finds a TH-1 & TH-2 thermistor failure during thermostat stop or during the first 3

minutes of compressor operation, it shuts down the air conditioner.

Line Low Voltage Protection:

(Values in parenthesis refer to 115VAC types).

The system will inhibit all output relays when line voltage fall below the following limits forover 10 seconds. The detection tolerance should not exceed ±2V.

1. When the compressor run, if the line voltage fall below:

175V (98V±1V) RMS for Rotary Compressor (TAC-460 DIP Switch 2 is On) or;

180V (100V±1V) RMS for Reciprocating Compressor (TAC-460 DIP Switch 2 is Off) or;

Note: If the line voltage fall below 161V (82V) during the compressor run, the system

should be stopped immediately (without any delay).

2. When the compressor off, if the line voltage fall below:



In both cases, the POWER indicator LED shall flash indicating the power failure conditions.

3. The system shall be restored to its last operation or command if the line voltage sustain formore than 1±0.1 minute above the minimum values stated in (b) above.

4. During compressor start-up the line voltage may fall for 4 sec. below:



Note: If the line voltage fall below 147V (83V) for 1 sec. during the compressor start-up, the

system should be stopped immediately (without any delay).

5. If the voltage drop sustain for longer period, the compressor shall be stopped for 5 min.

then after, re-entry the start-up operation.

6. After two consecutive failures to restart, the restart delay shall be increased to 10 min. This

shall be indicated by flashing of the POWER LED on the display board. In addition, the

maintenance indicators COMPRESS & IMPEDANCE shall lit.

1. After five consecutive failures to restart, the system shall go OFF automatically.

Recovery from this Power Failure is done by sending Off command to system and re-entry

to On (by mean of TAC-490 R/C or 3-position slide switch).

TAC-404

70

Line Over Voltage Protection:

(Values in parenthesis refer to 115VAC types).

This routine should run on interrupt basis. The routine shall inhibit all output relays when the

power line voltage rise above stated limits:

1. During compressor run, if the line voltage rise above:

262±4VRMS (134V±2V) for 10 sec.;

2. During compressor rest, if the line voltage rise above:

267±4VRMS (136V±2V) for 10 sec.;

In both cases, the POWER indicator LED shall flash indicating the power failure conditions.

3. The system shall recover to its last operation or command after the line voltage sustains

below 267VRMS (136V±2V) for 3 minutes.
