1 - SAFETY CONSIDERATIONS

1.1 - General

Installation, start-up and servicing of equipment can be

hazardous if certain factors particular to the installation are not

considered: operating pressures, presence of electrical

components and voltages and the installation site (elevated

plinths and built-up up structures). Only properly qualified

installation engineers and highly qualified installers and

technicians, fully trained for the product, are authorised to

install and start-up the equipment safely. During all servicing

operations all instructions and recommendations which appear

in the installation and service instructions for the product, as

well as on tags and labels fixed to the equipment and components

and accompanying parts supplied separ-ately, must be read,

understood and followed.

Apply all standard safety codes and practices.

Wear safety glasses and gloves.

Use the proper tools to move heavy objects. Move units

carefully and set them down gently.

1.2 - Avoid electrocution

Only personnel qualified in accordance with IEC (Interna-

tional Electrotechnical Commission) recommendations may be

permitted access to electrical components. It is particu-larly

recommended that all sources of electricity to the unit be shut

off before any work is begun. Shut off the main power supply

at the main circuit breaker or isolator.

IMPORTANT: This equipment uses and emits electro-

magnetic signals. Tests have shown that the equipment

conforms to all applicable codes with respect to electro-

magnetic compatibility.

RISK OF BURNS: Electrical currents cause components to

get hot either temporarily or permanently. Handle power

cable, electrical cables and conduits, terminal box covers and

motor frames with great care.

2 - GENERAL DESCRIPTION

2.1 - Service interface

Service inteface is a command for exclusively use by service

and installers personnel.

The purpose of this contol are:

Diagnostic

Parameters' configuration

Note: ON/OFF, COOL/HEAT and dual set-point functions are

not available on the service interface.

2.2 - Pro-Dialog

Pro-Dialog is a system for controlling single circuit 30RA air-

cooled liquid chillers or air-to-water 30RH heat pumps. Pro-

Dialog controls compressor start-up needed to maintain the

desired heat exchanger entering or leaving water temperature. In

cooling mode it controls the operation of the fans to maintain the

correct condensing pressure. For heat pump units it controls

and optimises the defrost cycles in order to minimize the

heating capacity reduction. Safety devices are constantly

monitored by Pro-Dialog to ensure their safe operation. Pro-Dialog also gives access to a Quick Test program covering all

inputs and outputs.

All PRO-DIALOG Plus control can work in accordance with

two independent modes:

Remote mode: the machine is controlled by remote contacts

volt-free contacts (available simplified control AJRC).

CCN mode: the machine is controlled by commands from

the Carrier Comfort Network (CCN). In this case, a data

communication cable is used to connect the unit to the

CCN communication bus.

The operating mode must be chosen with the Start/Stop button

described in sections 3 and 4.2.1. When the PRO-DIALOG

Plus system operates autonomously (Remote mode) it retains all

of its own control capabilities but does not offer any of the

features of the CCN network.

2.3 - Abbreviations used

The following abbreviations are used frequently:CCN : Carrier Comfort Network

CCn : Operating type: CCN

LED : Light Emitting Diode

LOFF : Operating type: Local OffL-On : Operating type: Local On mode

L-Sc : Operating type: Local On following a time schedule

rEM : Operating type: by remote contacts

SCT : Saturated Condensing Temperature

SIO : Sensor Bus (internal communication bus linking the

basic board)

SST : Saturated Suction Temperature

4.3.10.4 - Automatic testsThe automatic test function verifies the integrity of the analo-

gue entries and activates the outputs in sequence. For each test

't XX' is displayed on the user interface. 'xx' indicates the

number of the test in progress. When a test has been completed,

the following test is automatically activated.

A message may appear, asking the operator for a validationwith the Enter key, if the control cannot automatically verify a

sensor value or an output status. If the value read or the output

status is incorrect, the operator must press a different key (not

the Enter key) to cancel the automatic test procedure.

4.3.11.6 - Description of the Time Schedules sub-menusThe control provides two timer programs: schedule 1 and

schedule 2 that can be activated if the unit is equipped with an

optional CCN/clock board (if the CCN/clock board is not

installed, the two schedules are permanently in occupied

mode).

The first timer program (schedule #1) provides a means to

automatically switch the unit from an occupied mode to an

unoccupied mode: the unit is started during occupied periods.

The second timer program (schedule #2) provides a means to

automatically switch the active setpoint from an occupied

setpoint to an unoccupied setpoint: cooling setpoint 1 is used

during occupied periods, cooling or heating setpoint 2 during

unoccupied periods. Heating setpoint 3 is activated during

holiday periods. For additional information on set-point

activation see section 5.4.1.

Each schedule consists of eight time periods set by the

operator. These time periods can be flagged to be in effect ornot in effect on each day of the week plus a holiday period (see

section 4.3.11.7 on public holidays). The day begins at 00.00

hours and ends at 24.00 hours.

Program is in unoccupied mode unless a schedule time period

is in effect. If two periods overlap and are both active on the

same day, the occupied mode takes priority over the

period.

Each of the eight periods can be displayed and changed with

the aid of a sub-sub-menu. The table below shows how to

access the period configuration. Method is the same for thetime schedule #1 or the time schedule #2.

4.3.11.8 - Description of the Broadcast sub-menuThe controller provides a broadcast configuration menu which

you can use to configure the unit to be the CCNs broadcaster,

responsible for transmitting the time, outdoor temperature, and

holiday flags to all system elements.

This menu also authorises setting the date of the daylight

saving time. There should be only one broadcaster in a CCN, sothis table should not be configured if any other system element

is acting as broadcaster. These menus are only accessible, if the

unit is equipped with an optional CCN/clock board.

ATTENTION: If the unit operates in standalone mode (not

CCN connected) this menu can also must be used if the holi-

day function is used or to correct for daylight saving time.

4.3.11.7 - Description of the Holidays sub-menusThis function is used to define 16 public holiday periods. Each

period is defined with the aid of three parameters: the month,

starting day and duration of the public holiday period. During

these public holidays the controller will be in occu-pied or

unoccupied mode, depending on the programmed periods

validated for public holidays (see section 4.3.11.6).

Each of these public holiday periods can be displayed and changed

with the aid of a sub-menu. These menus are only accessible,

if the unit is equipped with an optional CCN/clock board.

ATTENTION: The broadcast function must be activated to

utilise the holiday schedule, even if the unit is running in stand-

alone mode (not connected to CCN). See section 4.3.11.8.

On to OFF delay is always applied.


22/2622

The following table summarises the possible selections

depending on the control types (remote or CCN) and the

following parameters:

Heating/cooling operating mode Control contact 3:status of control contact 3. Contol contact 3 selection:this selection, indicates if

contact 3 is used for dual setpoint control or for demand

limit control (see User Configuration menu, section

4.3.11).

Schedule 2 status:schedule for setpoint selection. See

section 4.3.11.6.

5.2 - Evaporator water pump controlThe unit controls one evaporator water pump. The evaporator

water pump is turned on when this option is configured (see

User configuration) and when the unit is in one of the on modes

described above or in delay mode. Since the minimum value for

the delay at start-up is 1 minute (configurable between 1 and 15

minutes), the pump will run for at least one minute before the

first compressor starts. The pump is kept running for 20 seconds

after the unit goes to stop mode. The pump keeps working

when the unit switches from heating to cooling mode or vice-

versa. It is turned off if the unit is shut down due to an alarmunless the fault is a frost protection error. The pump can be

started in particular operating conditions when the evaporator

heater is active (see section 5.3).

The control provides a means to automatically start the pump

each day at 14.00 hours for 2 seconds when the unit is off, if

configurated. Starting the pump periodically for few seconds

increases the life-time of the pump bearings and the tightness

of the pump seal.

5.1 - Heating/cooling operation

5.1.1 - GeneralThe heating/cooling selection applies to 30RA (liquid chillers)

units, controlling a boiler and to 30RH (heat pumps) units.

Heating/cooling control can be automatic or manual.

If the unit is in standby it does not cool or heat, and no

compressor can be activated.

The table below, summarizes the unit HEAT/COOL mode with

regard to the following parameters:

status: unit ON/OFF status

ctrl_typ: unit control type

hc_sw: switch control status when the unit is under remote

operating mode

HC_SEL: HEAT/COOL select while running in CCN

control type

Note: A cooling only unit (A/C) with no boiler option, operatesalways in cooling mode.

When an heat pump unit (HP) operates in cooling mode or

it is in defrost cycle, the reversing valve will be powered.

The valve will not be powered in heating mode.

Valve position will be modified when unit capacity is 0%.

5.3 - Evaporator heater control (Option)

The evaporator heater can be energised to protect an evaporator

that can be damaged by freezing, if the unit is shut down for a

long time at low outdoor temperature. The evaporator pump

can be started, if conditions get worse.

NOTE: Evaporator heater control parameters can be

modified, using the Service configuration.

5.4 - Control point

The control point represents the water temperature that the unit

must produce. The inlet water is controlled by default, but the

outlet water can also be controlled (requires a Service

configuration modification).

Control point = active setpoint + reset

5.4.1 - Active setpointTwo setpoints can be selected as active in cooling mode and

three in heating mode. Usually, the second cooling setpoint isused for unoccupied periods or for ice storage (brine unit). The

second setpoint in heating mode is used for unoccupied

periods, and the third heating setpoint is used for holiday

periods or public holidays. Depending on the current opera-

tions, the active setpoint can be selected by choosing the item

in the Information menu, with the users volt-free contacts,

with network commands or with the setpoint timer program

(schedule 2).
