SEQUENCE OF OPERATION FOR GAM5 AIR HANDLERS

GAM5 Sequence of Operation:

Abbreviations• TDR = Time Delay Relay

• EVC = Expansion Valve Control

• EEV = Electronic Expansion Valve

• YI = Y signal into the EVC from the comfort control

• YO = Y signal out of the EVC from the comfort control

• OEM = Original Equipment Manufacturer

See unit, electric heat, and field wiring diagrams for addi-tional information.

Continuous Fan

IMPORTANT: If the indoor air exceeds 60% relative humidity or simply feels uncomfortably humid, it is recommended that the indoor fan only be used in the AUTO mode.1. R-G contacts close on comfort control sending 24VAC to

the G terminal on the fan TDR

2. Low speed contacts close in the TDR and send 24VAC on terminal labeled “LOW’.

3. Blower motor will now run on low speed. Speed is field selectable.

Heat Pump OD (cooling)1. R-Y contacts close on the comfort control sending 24VAC

to Y terminal on TDR and the YI (Y In) terminal on the EVC.

2. R-G contacts also close on the comfort control sending 24VAC to the G terminal on the TDR. (The combination of 24VAC on terminals Y and G on the TDR will close the high speed contacts of the TDR)

3. R-O contacts on the comfort control close sending 24VAC to the O terminal on the EVC. This signals the EVC that the unit is in cooling mode. The EVC will control the EEV to maintain the correct superheat.

4. Normally closed contacts on the EVC will pass 24VAC to the YO terminal providing power to the outdoor unit control circuit

5. The blower motor will now run on high speed. Speed is field selectable.

Heat Pump OD (heating)1. R-Y contacts close on the comfort control sending 24VAC

to Y terminal on TDR and the YI (Y In) terminal on the EVC

2. R-G contacts also close on the comfort control sending 24VAC to the G terminal on the TDR. (The combination of 24VAC on terminals Y and G on the TDR will close the high speed contacts of the TDR) The blower motor will now run on high speed.

3. The combination of 24VAC on the Y terminal and zero volts on the O terminal signals the EVC that the unit is in heat-pump heating mode.


5. The blower motor will now run on high speed

Cooling OD1. R-Y contacts close on the comfort control sending 24VAC

to Y terminal on TDR and the YI (Y In) terminal on the EVC

2. R-G contacts also close on the comfort control sending 24VAC to the G terminal on the TDR. (The combination of 24VAC on terminals Y and G on the TDR will close the high speed contacts of the TDR)

3. R-O jumper on the TDR sends 24VAC to the O terminal on the EVC. This signals the EVC that the unit is in cool-ing mode. The EVC will control the EEV to maintain the correct superheat.


5. The blower motor will now run on high speed

Electric Heating1. R-W contacts close on the comfort control sending 24VAC

to the W terminal on the TDR. 24VAC is also sent to EHC to energize the heat relay.

2. R-G contacts close on the comfort control sending 24VAC to the G terminal on the TDR. (The combination of 24VAC on terminals W and G on the TDR will close the high speed contacts of the TDR)

3. WJ contacts on the TDR close providing an interlock circuit to allow the electric heat relays to operate.

The comfort control must be setup to control R-G contacts with a call for electric heat. This closes the interlock circuit and allows the heat relay circuit to be energized.

Optional Condensate Switch1. An optional OEM condensate switch can be installed

within the unit. This switch is only available through the National Distribution Center or Global Parts.

2. Switch contacts are normally open and close when water level rises. The closed switch will interrupt current flow to the YO terminal and de-energize the OD unit.

3. Switch is only operational during cooling mode. Conden-sate overflow is not operational during heating or defrost modes.

Standard aftermarket condensate switches cannot be used within the unit but can be installed exterior of the unit. The 3rd party condensate overflow switch must be wired between Y of the thermostat and YI of the EEV control.

DIP SWITCH SETTING - Refrigeration Switch

Note: Ensure that the system refrigerant is set to match your application, either R-410A or R-22. using the Refrigerant Switch located on the Ex-pansion Valve Control board (EVC) in the Control Pocket.

Factory default is R-410A.

Note: A “power cycle” is needed for the EVC to recognize the change.

Wire Ties

Freeze Protection1. The EVC control has the ability to sense when the coil is

beginning to ice. When this event occurs, the contacts to the YO circuit will open and de-energize the OD unit.

2. The indoor blower motor will continue to run to aid in de-frosting the coil. After the coil has sufficiently defrosted, the YO contacts will close and cooling operation will begin again.

Fan Off Delay1. The TDR has a dip switch that can enable a 90 second

fan off delay anytime a fan call is made from the comfort control. The factory default is ON. To disable the delay, turn power off to the unit, turn the dip switch to the off position and turn power back on to the unit.

Electronic Expansion Valve Test

Note: Close Valve and Open Valve Tests are active in any mode of operation

Test Pins: OPEN, CLOSE, TEST (See J4 on EVC Board)

Close Valve Test - Touch CLOSE pin to TEST pin.

EEV drives closed (5 seconds max) and stays closed for 1.5 minutes (90 seconds).

1) Status LED will be flashing. 2) Gauges should indicate suction pressure dropping.

• Valve is working. • LPCO may trip.

Note: The Close Valve Test will exit after 1.5 minutes (90 seconds) and will not reinitiate (requires a break and make to initialize). To clear faults stored in memory, apply a jumper between Close and Test pins for 10 seconds.

Open Valve Test - Touch OPEN pin to TEST pin.

EEV drives open (5 sec max) and stays open for 30 seconds.

1) Status LED will be flashing. 2) Temperature probe should indicate superheat falling.

• Valve is working.

Note: If jumper is left on pins, the OPEN VALVE TEST will be cleared after 30 seconds and will not reinitiate (requires a break and make to reinitialize).

Exit Test Mode - The Open Valve Test or Closed Valve Test can be cancelled by jumping to the opposite mode Test pin. The system will return to normal super heat control.

HIGH SUPERHEAT

Superheat above 30F at OD unitStart Here

Is subcooling at the outdoor unit

between 8-12F?

Verify line set is properly sized for

applicationNO

Verify that OD condenser coils

are clean

Add refrigerant until subcooling reaches ~10F

Recheck superheat

Is liquid line temperature at the indoor unit within 8F of outdoor liquid line

temperature?

Verify line set size and charge is

correctNO

Perform “OPEN VALVE” test at

EVC.

YES

Does superheat drop

below 30F?

Is indoor temperature

>85F?NO

Perform “CLOSE VALVE” test at

EVC.YESDoes suction

pressure go down?

EEV and coil are working. Replace EVC

Check operation

YES

YESPerform

temperature sensor check

YES

NO

The system is running at maximum capacity and this

may be causing the high superheat. Wait until the

indoor temperature is less than 80F and check the

superheat again.

Replace EEV. Check operation

Ohm coil per Stepper Motor Tables

NO

Is ohm reading correct?

YES

Replace coil NO

Constant Torque Motor Troubleshooting

Does blower wheel turn

freely?

Turn off power. Check set screw

position and motor bearings. Correct

or replace as needed.

Check operation

NO

Is ~230 VAC measured between terminals “L” &

“N” on the motor? See Figure 1

YES

High voltage should always be present.

Correct high voltage wiring.

NO

Is ~24 VAC measured between the wire connected to “C” on the motor and the wire connected to terminal 1

thru 5 on the motor? See Figure 2

YES

YES

Replace motor.Check operation

Motor does not run

Turn comfort to “FAN ON” mode

Is 24VAC measured from terminal 8(G) to terminal 9(BL) on the

fan control?

NO

Correct wiring. Check operation

NO

Replace fan control. Check operation

YES

This terminal block is located on the motor. Look for labels below

on the motor side of the connection.

FIGURE 2

NOTE: The fan control has a 90 second “OFF” delay that is factory set on. To turn this

feature off, turn dip switch to 0 and cycle power to the unit.
