The compressors in circuit A are labelled A1, A2 and A3. Those in circuit B are B1 and B2. 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 separately, 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. The 61WG/30WG units however have only one circuit A with one or two compressors (A1, A2). The following abbreviations are used frequently: Carrier Comfort Network CCN DHW Domestic hot water HDC Heating device control LED Light Emitting Diode LEN Internal communication bus linking the main board to the slave boards SCT Saturated condensing temperature SHC Space heating control SST Saturated suction temperature EXV Electronic expansion valve PD-AUX Auxiliary input/output board 1.2 - Avoid electrocution 3 - HARDWARE DESCRIPTION Only personnel qualified in accordance with IEC (International Electrotechnical Commission) recommendations may be permitted access to electrical components. It is particularly 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. 3.1 - General IMPORTANT: This equipment conforms to all applicable codes regarding electromagnetic compatibility. 2 - GENERAL DESCRIPTION 2.1 - General The control system consists of an NRCP2-BASE board and a user interface. All boards communicate via an internal LEN bus. The NRCP2-BASE board continuously manages the information received from the various pressure and temperature probes. The NRCP2-BASE master board contains the program that controls the unit. The user interface includes an alphanumeric seven-line display, two LEDs with five navigation keys as well as a contrast control wheel. The 61WG/30WG units have one refrigerant circuit with one or two compressors. Pro-Dialog is an electronic control system to regulate water-cooled units with or without hydronic module of the following types: • 61WG non-reversible heat pumps • 30WG water-cooled liquid chillers. Pro-Dialog controls: • compressor start-up to control the water loop • fixed or variable-flow pumps to optimise the operation of the refrigerant circuit As standard Pro-Dialog offers three on/off commands: • Local - on/off command using the keyboard • Remote - wired on/off command using volt-free contacts • Network - Carrier Comfort Network (CCN) on/off command. The command type is selected in advance by keyboard. 3 Control board Green LED Unit has stopped Contrast control wheel Unit starts up Unit in operation Back to the previous screen Red LED No alarm Warning Circuit or complete unit error Up/Down key - Navigation - Modification On/off key Enter key - Unit stopped - List of available operating modes (only in local mode) 3.2 - Electrical supply to boards All boards are supplied from a common 24 V a.c. supply referred to earth. CAUTION: Maintain the correct polarity of the power supply connection of the boards, to ensure that they are not damaged. In the event of a power supply interrupt, the unit restarts automatically without the need for an external command. However, any faults active when the supply is interrupted are saved and may in certain cases prevent a circuit or unit from restarting. 3.3 - Light emitting diodes on boards All boards continuously check and indicate the proper operation of their electronic circuits. A light emitting diode (LED) lights on each board when it is operating properly. • The red LED that flashes for a two-second period - one second on, one second off - indicates correct operation. A different rate indicates a board or a software failure. • The green LED flashes continuously on all boards to show that the board is communicating correctly over its internal bus. If the LED is not flashing, this indicates a LEN bus wiring problem. • The orange LED of the master board flashes during any communication via the CCN bus. - Validation - Selection access Water system pressure sensors As an option, two electronic sensors are used to measure the suction and the discharge pressure of the water pump. The water flow rate is calculated, the unit is protected against water flow losses and the pump is protected against cavitation (low pump entering pressure). Thermistors The water temperature sensors are installed in the entering and leaving side. Two optional water temperature sensors can be used for master/slave assembly control (in the case of leaving water control). 3.5 - The controls Water circulation pumps The controller can regulate each water heat exchanger pump and takes care of automatic changeover between pumps. Variable-flow pumps can control the heat exchanger temperature difference or the water pressure difference. Boiler If there is a unit fault in the heating mode this output authorises start-up and shutdown of a boiler. Immersion heaters The outputs of the AUX1 board permit control of the electric resistance heaters. They are used as a supplementary heating source in the heating mode. 3.4 - The sensors 3.6 - Connections at the user terminal block Refrigerant pressure sensors Two types of electronic (high and low-pressure) sensors are used to measure the suction and discharge pressure in each circuit. 3.6.1 - General description The contacts below are available at the user terminal block on the NRCP2-BASE boards. Some contacts can only be used if the unit operates in remote operating type (Remote). 4 NRCP2-BASE control board Optional PD-AUX board J2A J12 J2B J3 J3 J4 The following table summarises the connections at the user terminal block.

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. The third timer program (schedule 3) allows the unit to switch to the domestic hot water production mode. The DHW mode is allowed during occupied periods. Each schedule consists of eight time periods set by the operator. These time periods can be flagged to be in effect or not in effect on each day of the week plus a holiday period. The day begins at 00.00 hours and ends at 23.59 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 unoccupied period. 14 DESCRIPTION Element number Bus number Communication speed Description Software version Serial number Each of the eight periods can be displayed and changed with the aid of a sub-sub-menu.

LOFF: local off, L-C: local on, L-SC: local schedule, REM: remote, CCN: network, MAST: Master • Remote start/stop contacts: these contacts are used when the unit is in remote operating type (Remote). See sections 3.6.2 and 3.6.3. • CHIL_S_S: this network command relates to the unit start/stop when the unit is in network mode (CCN). ACTIVE OPERATING TYPE • • • • Command set to Stop: the unit is halted. Command set to Start: the unit runs in accordance with schedule 1. Start/Stop schedule: occupied or unoccupied status of the unit as determined by the chiller start/stop program (Schedule 1). Master control type. This parameter is used when the unit is the master unit in a two chiller lead/lag arrangement. The master control type determines whether the unit is to be controlled locally, remotely or through CCN (this parameter is a Service configuration). CCN emergency shutdown: if this CCN command is activated, it shuts the unit down whatever the active operating type. General alarm: the unit is totally stopped due to failure.

It can be done manually (or automatically on a unit with outside air temperature sensor). In automatic mode the outdoor temperature determines the heating/cooling/standby changeover based on the two threshold values configured by the user (see RESETCFG menu). If the unit is in standby it does not cool or heat, and no compressor can be activated. The diagram below summarises the operating principle in automatic mode. 16 HEATING * STANDBY Heating threshold* COOLING Cooling threshold Outdoor temperature This threshold does not apply to cooling only units that do not control a boiler. 5.2.2 - Heating/cooling/auto selection The table below summarises the unit heating/cooling operation, based on the following parameters: • Control type: indicates whether the unit operates in local, remote or CCN mode. See section 5.1. • Unit on/off status: indicates whether the unit is shut down (not authorised to start) or in operation (or authorised to start). • Heating/cooling/auto selection in local mode: operating mode selected via the user interface. See GENUNIT menu.

The pump is turned on when this option is configured (see PUMPCONFIG) 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. This contact checks the status of a loop (water flow switch and customer safety loop, see chapter 3.6). It prevents the unit from starting if it is open when the delay at start-up has expired. This open contact leads to an alarm shut-down, if the unit is running. The pump is kept running for 2 minutes 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 alarm unless the fault is a frost protection error. The pump can be started in particular operating conditions when frost protection of the heat exchanger is active (see chapter “Control point”). See chapter “Master/slave assembly” for the particular heat exchanger pump control for the slave unit (master/slave assembly). The control point represents the water temperature that the unit must produce. The heat exchanger entering water temperature is controlled by default, but the heat exchanger leaving water temperature can also be controlled (requires a Service configuration modification). If the pump with variable flow option has been selected (factory-installed option), it is possible to control the water flow in three ways (service parameters): • adjusted fixed flow rate, • constant temperature difference, • constant pressure difference. In this way it is possible to adjust the water loops and to optimise pump operation. 5.5 - Control point Control point = active setpoint + reset 5.5.1 - Active setpoint Three setpoints can be selected as active in cooling mode and two in heating mode. Usually, the second setpoint is used for unoccupied periods. Depending on the current operating type, the active setpoint can be selected: • by choosing the item in the GENUNIT menu, • via the user’s volt-free contacts, • via network commands • via the setpoint timer program (schedule 2). The control provides a means to automatically start the pump each day at 14.00 hours for 2 seconds when the unit is off (pump anti-stick function). Starting the pump periodically for few seconds increases the life-time of the pump bearings and the tightness of the pump seal. 17 LOCAL OPERATING MODE PARAMETER STATUS Heating/cooling Local setpoint operating mode selection Cooling sp 1 Cooling sp 2 Cooling Ice_sp Time schedule 2 status - Cooling Cooling Heating Heating Heating Heating Heating occupied unoccupied occupied unoccupied auto auto sp1 sp 2 sp 3 auto auto Active setpoint Cooling setpoint 1 Cooling setpoint 2 Ice storage cooling setpoint Cooling setpoint 1 Cooling setpoint 2 Heating setpoint 1 Heating setpoint 2 Heating setpoint 3 Heating setpoint 1 Heating setpoint 2 REMOTE OPERATING MODE PARAMETER STATUS Heating/cooling operating mode Cooling Cooling Heating Heating Setpoint selection contact sp 1 (open) sp 2 (closed) sp 1 (open) sp 2 (closed) Active setpoint Cooling setpoint 1 Cooling setpoint 2 Heating setpoint 1 Heating setpoint 2 5.5.2 - Reset Reset means that the active setpoint is modified so that the machine capacity required is adjusted to be as close as possible to the demand. This modification is in general a reaction to a drop in the load. For the Pro-Dialog control system, the source of the reset can be configured in the HCCONFIG configuration: it can be provided either by the outdoor temperature (that gives a measure of the load trends for the building) or by the return water temperature (heat exchanger delta T, gives an average building load). In response to a drop in the outdoor temperature or to a drop in delta T, the cooling setpoint is normally reset upwards in order to optimise unit performance: In both cases the reset parameters, i.e. slope, source and maximum value, are configurable in the RESETCFG menu (see section 4.3.8). Reset is a linear function based on three parameters. • A reference at which reset is zero (outdoor temperature or delta T - no reset value). • A reference at which reset is maximum (outdoor temperature or delta T - full reset value). • The maximum reset value. 18 % Building load Reset example in cooling mode based on the outside temperature Reset value The following tables summarise the possible selections depending on the control types (local, remote or network) and the following parameters: • Setpoint select in local control: item LSP_SEL in the GENUNIT menu permits selection of the active setpoint, if the unit is in local operating type. • Heating/cooling operating mode. • Setpoint selection contacts: setpoint selection contact status. • Schedule 2 status: schedule for setpoint selection. Outdoor temperature (OAT) Heat exchanger delta T Legend A Maximum reset value B OAT or delta T for no reset C OAT or delta T for full reset D Building Load 5.6 - Capacity control This function adjusts the number of active compressors to keep the heat exchanger water temperature at its setpoint. The precision with which this is achieved depends on the capacity of the water loop, the flow rate, the load, and the number of stages available on the unit. The control system continuously takes account of the temperature error with respect to the setpoint, as well as the rate of change in this error and the difference between entering and leaving water temperatures, in order to determine the optimum moment at which to add or withdraw a capacity stage. If the same compressor undergoes too many starts (per hour) or runs below one minute each time it is started this automatically brings about reduction of compressor starts, which makes leaving water temperature control less precise. The high pressure, low pressure or defrost unloading functions can also affect temperature control accuracy. Compressors are started and stopped in a sequence designed to equalise the number of start-ups (value weighted by their operating time). 5.7 - Demand limit The demand limit is used to restrict the unit power consumption. The Pro-Dialog control system allows limitation of the unit capacity, using user-controlled volt-free contacts. The unit capacity can never exceed the limit setpoint activated by these contacts. The limit setpoints can be modified in the SETPOINT menu. 5.8 - Night mode The night period is defined (see GENUNIT configuration) by a start time and an end time that are the same for each day of the week. During the night period the unit capacity may be limited. 5.9 - Control of a boiler NOTE: The control of the electric heating stages or of a boiler is not authorised for slave units. The unit can control the start-up of a boiler, if it is in heating mode. When the boiler is operating, the unit water pump is stopped. The unit and a boiler cannot operate together. In this case the boiler output is activated in the following conditions: • The unit is in heating mode, but a fault prevents the use of the heat pump capacity. • The unit is in heating mode, but works at a very low outdoor temperature, making the heat pump capacity insufficient. It is possible to adjust the boiler start-up based on the outside temperature (HCCONFIG menu). One of the functions of the master unit (depending on its configuration) may be the designation, whether the master or slave is to be the lead machine or the follower. The roles of lead machine and follower will be reversed when the difference in running hours between the two units exceeds a configurable value, ensuring that the running times of the two units are automatically equalised. The changeover between lead machine and follower may take place when the assembly is started up, or even whilst running. The running time balancing function is not active if it has not been configured: in this case the lead machine is always the master unit. Two Pro-Dialog+ units can be linked to produce a master/ slave assembly. The two machines are interconnected over the CCN bus. All parameters required for the master/slave function must be configured through the Service configuration menu. The lead machine will always be started first. When the lead machine is at its full available capacity, start-up delay (configurable) is initialised on the follower. When this delay has expired, and if the error on the control point is greater than 1.7°C, the follower unit is authorised to start and the pump is activated. The follower will automatically use the master unit active setpoint. The lead machine will be held at its full available capacity for as long as the active capacity on the follower is not zero. When the follower unit receives a command to stop, its evaporator water pump is turned off with 20 seconds delay. Master/slave operation requires the connection of a temperature probe at the common manifold on each machine, if the heat exchanger leaving water temperature is controlled. It is not required, if the entering water temperature is controlled. In the event of a communication fault between the two units, each shall return to an autonomous operating mode until the fault is cleared. If the master unit is halted due to an alarm, the slave unit is authorised to start without prior conditions. The master/slave assembly can operate with constant or variable flow. In the case of variable flow each machine must control its own water pump and automatically shut down the pump, if the cooling capacity is zero. ATTENTION: For heat pumps operating in master/slave mode and using an NRCP2 board or equipped with electric heater stages control must be on the entering water temperature. For constant flow operation the pumps for each unit are continuously operating, if the system is operating. The master unit can control a common pump that will be activated, when the system is started. In this case the slave unit pump is not used. 5.11 - Heating module (HDC) control 5.10 - Master/slave assembly All control commands to the master/slave assembly (start/ stop, setpoint, heating/cooling operation, load shedding, etc.) are handled by the unit which is configured as the master, and must therefore only be applied to the master unit. They will be transmitted automatically to the slave unit. The master unit can be controlled locally, remotely or by CCN com-mands. Therefore to start up the assembly, simply validate the Master operating type (Master) on the master unit. If the Master has been configured for remote control then use the remote volt-free contacts for unit start/stop. The slave unit must stay in CCN operating type continuously. To stop the master/slave assembly, select Local Off on the master unit or use the remote volt-free contacts if the unit has been configured for remote control. 61WG units are specially designed to optimise the operation of heating installations that require hot-water production for traditional heating and domestic hot water (DHW) requirements. In this case an AUX board is included in the unit control box. The Pro-Dialog+ control of the 61WG includes algorithms that permit constant and automatic optimisation: • control of a three-way directional on/off valve based on the heating or domestic hot water requirements • control of the electric heater stages can complement the heating loop • hot water setpoint reset (heating application) based on the outside air temperature • priority control between heating and domestic hot water applications. 5.11.1 – Sensor An optional outside air temperatrure sensor can be used to reset the setpoint or determine the summer/winter mode. 19 5.11.2 – Controls The heating module controls the following elements: • A three-way valve to switch over to domestic hot water production • An additional water pump in the heating circuit • Up to four electric heating stages (for supplementary safety stage heating) 5.11.3 – User connection terminals Three volt-free contacts are available at a user connection terminal board: • A contact for DHW demand from the tank • A volt-free contact for DHW priority • A volt-free contact for the summer mode 5.11.4 – Control of additional electric heater stages The heat pump units can control up to four electric heater stages as supplementary heating. Electric heater stages are activated to supplement the heating capacity if the following conditions are satisfied: • The unit uses 100% of its available heating capacity or the unit is limited in its operation by a protection mode (e.g. low suction temperature protection) and in all cases cannot satisfy the heating demand. • The outside temperature is below a configurable threshold (see HCCONFIG menu) • Unit demand limitation is not active. If required the user can configure the last electric heater stage available as a safety stage. That safety stage is only activated in addition to the other stages, if there is a unit fault that prevents the use of the heating capacity. The other electric heater stages continue to operate a described above. The electric heater stages only operate in the heating mode, but not during domestic hot water production. 5.11.5 – Heating or domestic hot water A three-way valve permits switching the heating capacity to a heating circuit (fan coil units, radiators or floor heating), or to a domestic hot water tank. The unit requests changeover to the domestic hot water mode if all the following conditions have been met: • The volt-free tank request contact is closed AND • Time schedule 3 is in an occupied period OR the volt-free priority contact is closed. Based on the operating mode the water setpoint is adjusted: • In heating mode, setpoints hsp1 and hsp2 are used. They can be modified by user reset or based on the outside temperature. • In domestic hot water production mode setpoint hsp3 is used. No setpoint reset is used. The unit requests changeover to the heating mode, if at least one of the following conditions applies: • The volt-free tank request contact is open OR • The maximum operating duration in the DHW mode has finished OR • Time schedule 3 is in an unoccupied period. 20 If a mode change is requested while a compressor is operating, it is stopped before the three-way valve changes to the new mode, and then the unit is re-started. If the unit is in domestic hot water production mode, a “DHW” message is displayed on the user interface next to the current operating mode. Example: “Local Running DHW”. 5.11.6 – Summer mode The summer mode is activated when the outside temperature exceeds the parameter threshold summ_oat during the summ_on time. It is deactivated if the outside temperature returns to a lower value than the parameter threshold summ_oat during the summ_off time. The summer mode can also be activated if the volt-free contact SUMM_SW is closed. 5.11.7 – Additonal water pump An additional water pump, installed in the heating water circuit starts if the summer mode is deactivated. If the anti-stick function is configured, the additional water pump starts periodically. 5.12 - Condensing pressure control - 30WG unit in cooling mode The control can regulate the following configurations: • Drycooler and variable-speed condenser pump. The fixed fan stages and the pump speed are controlled to maintain a fixed condensing setpoint (value adjustable). • Variable-speed condenser pump (without drycooler control). The condenser pump integrated into the unit is controlled to maintain a fixed condensing setpoint (value adjustable). • Drycooler and three-way valves. The fixed fan stages and the three-way valve position are controlled to permit start-ups at low outside temperatures and maintaining a fixed condensing setpoint (value adjustable). • Three-way valve only (without drycooler control). The position of the three-way valve is controlled to maintain a fixed condensing setpoint (value adjustable). • Drycooler only (fixed or variable speed). Only the drycooler fan stages are controlled by reference to a fixed drycooler water outlet (value adjustable). The condensing setpoint is adjustable with item cond_sp in the SETPOINT table (SETPOINT menu, chapter 4.9.4). The condensing setpoint can be reset by reference to the outside temperature to optimise the operation of the condensing system. To set the condensing setpoint reset, the following adjustments are necessary: • item hr_sel = 2 (HCCONFIG menu, chapter 4.9.21), • items oathr_no, oathr_fu et hr_deg (RESETCFG menu, chapter 4.9.23). 6 - DIAGNOSTICS - TROUBLESHOOTING 6.1 - General The Pro-Dialog+ control system has many fault tracing aid functions. The local interface and its various menus give access to all unit operating conditions. If an operating fault is detected, an alarm is activated and an alarm code is stored in the Alarms menu, sub-menus CUR_ALRM and ALARMRST. 6.2 - Displaying alarms The alarm LED on the interface (see chapter 4.1) allows the quick display of the unit status. • A flashing LED shows that the circuit is operating but there is an alert. • A steady LED shows that the circuit has been shut down due to a fault. The ALARMRST menu on the main interface displays up to five fault codes that are active on the unit. 6.3 - Resetting alarms When the cause of the alarm has been corrected the alarm can be reset, depending on the type, either automatically on return to normal, or manually when action has been taken on the unit. Alarms can be reset even if the unit is running. This means that an alarm can be reset without stopping the machine. In the event of a power supply interrupt, the unit restarts automatically without the need for an external command. However, any faults active when the supply is interrupted are saved and may in certain cases prevent a circuit or a unit from restarting. A manual reset must be run from the main interface via the ALARMRST menu, item RST_ALM. Depending on the configuration in the GENCONF menu, access to the item may be protected by a password. 21 6.4 - Alarm codes Alarm Alarm Alarm description No. code Thermistor faults 1 th-01 Fluid sensor fault, evaporator water outlet 2 th-02 Fluid sensor fault, evaporator water inlet 3 th-06 Fluid sensor fault, condenser water outlet 4 th-07 Fluid sensor fault, condenser water inlet 5 th-10 Outside temperature sensor fault 6 th-11 HTWSTEMP fluid sensor fault (master/slave) 7 th-12 Suction sensor fault, circuit A 8 th-13 Suction sensor fault, circuit B 9 th-32 CHWSTEMP fluid sensor fault (master/slave) 10 th-36 Fluid sensor fault DRY_LWT 11 th-44 Sensor fault, discharge circuit A 12 th-45 Sensor fault, discharge circuit B Pressure transducer faults 13 Pr-01 Discharge pressure transducer fault, circuit A 14 Pr-02 Discharge pressure transducer fault, circuit B 15 Pr-04 Suction pressure transducer fault, circuit A 16 Pr-05 Suction pressure transducer fault, circuit B 17 Pr-24 Entering evaporator water pressure sensor fault 18 Pr-25 Leaving evaporator water pressure sensor fault 19 Pr-26 Entering condenser water pressure sensor fault 20 Pr-27 Leaving condenser water pressure sensor fault Communication with the slave boards 21 CO-BB Communication loss with the NRCP2 board Reset type Probable cause Action taken by the control Automatic when the temperature measured Defective thermistor by the sensor returns to normal As above As above Unit is shut down Automatic when the temperature measured Defective thermistor by the sensor returns to normal As above As above Unit is shut down As above As above As above As above As above As above As above As above As above As above As above As above As above As above As above As above Unit is shut down The master/slave mode is stopped Circuit is shut down As above The master/slave mode is stopped Unit is shut down Circuit is shut down Circuit is shut down Automatic when the voltage transmitted by the sensor returns to normal As above Defective transducer or installation fault As above Circuit is shut down As above As above As above As above As above As above Automatic when the voltage transmitted by the sensor returns to normal Automatic when the voltage transmitted by the sensor returns to normal As above Defective transducer or installation fault Defective transducer or installation fault As above Circuit is shut down As above As above As above Automatic when communication is re-established Installation bus fault or defective slave board Communication loss with the EXV board Communication loss with the PD-AUX 1 board As above As above Depending on the configuration, compressor A3 is shut down or circuit B is shut down.
