The remote off contact has priority over the keyboard commands, i.e. it is not possible to start the unit from the keyboard (or from remote supervision via serial port) until the remote poweron contact is enabled (contact closed on the terminal board). The remote off unit status is indicated on the display by the label OFF with a flashing LED. After enabling the unit closing the remote on/off contact the display shows the label STBY (standby) until the desired operating mode is selected using the appropriate button (see below for details). IC200CX EVO user manual Once the unit has been started also from the keyboard, the upper line of the display shows the regulation probe (water inlet temperature at the main heat exchanger), while in the lower line the outlet water temperature is shown.
In addition to the basic visualizations (unit status, operating mode, input and output water temperatures) it is possible to read the values of all the temperature and pressure probes, the thermostatic valve driver probes and the operating parameters.The alarms are displayed by an icon and a flashing alarm code. The procedures for displaying and modifying parameters are described in detail in the following paragraphs. 2.4 Key functions heat pump mode up key chiller mode down key set point menu Push and release Show chiller set point SetC, heat pump set point SetH and sanitary set point SetS Push once again In chiller or heat pump if the Energy saving or the Dynamic setpoint are enabled it shows the real setpoint Setr.

UNIT ON/OFF The unit can be switched ON and OFF in several ways: • From digital input configured as remote ON/OFF • From the keyboard • From time bands • From remote supervision/XWeb 3.1 ON/OFF by digital input The ON/OFF digital input has priority over the keyboard. The unit can be switched ON and OFF from keyboard only if the unit is in ON mode by the input (contact closed). If you do not intend to use the remote ON/OFF function via digital input, identify the relevant terminals in the wiring diagram and jumper them (terminals 12). ON/OFF Warning: the ON/OFF input is in no case intended as an thermoregulation input, i.e. IC200CX EVO it should not be connected to external control units or thermostats used for user manual temperature control. For this use it is advisable to act on the Energy saving contact (see below). The typical use of the ON / OFF contact is to turn the unit on and off in predefined periods by means of external mechanical clocks or relay devices controlled by SMS. With the contact inactive (no With active contact (bridge in bridge in the terminal board) terminal block) the unit is the unit is switched off, the enabled in the last selected display shows OFF. operating mode (see below).
3.2 ON/OFF by keyboard Press and release the heat pump mode key to turn the unit on in heating mode. Press and release the chiller mode key to turn the unit on in cooling mode. Note: with the unit in standby mode, i.e. activated by digital contact, but without ibeing switched on in chiller or heat pump mode, it is possible to view the measured variables through the display and manage the alarm situations by displaying and signaling them (see below) . When the unit is on, the mode LED indicates the functioning in chiller or heat pump, the pump icon turns on and then the operating icons of the condenser fans and the compressors are displayed. IC200CX EVO user manual 3.3 ON/OFF by remote supervision Switching ON/OFF, as well as complete management of the unit (change of mode, reading of temperatures, states, alarms, etc.) is possible via Modbus protocol on RS485 serial or via XWeb remote supervision system. Please refer to the dedicated manuals for details.
COOLING/HEATING OPERATION MODE The change of the unit operating mode (chiller mode, heat pump mode) can occur: • From digital input configured as mode change • From keyboard Attention: the factory setting is "keyboard mode change" for units ordered with the optional remote keypad, and "digital input mode change" for units without this accessory. The configuration can be modified, i.e. the mode change can be performed by digital input even on units equipped with a remote keypad. 4.1 Mode change by digital input If you intend to use the function change mode via digital input, identify the relevant terminals in the wiring diagram (terminals 18) and connect them to an external selector. Warning: during the changeover phase make sure to stay within the operating limits of the unit. For example, changing the heat pump mode to the chiller mode could cause to enter in the unit previously heated water above the limits allowed in the in cooling mode, causing malfunctions. It is strongly advisable to perform a unit stop with an appropriate duration before proceeding to change the operating mode. IC200CX EVO user manual mode With the contact inactive (no With active contact (bridge in bridge in the terminal board) terminal block) the unit is in the unit is in chiller mode. heat pump mode.

Pressing again, with the energy saving or with the dynamic set point activated (par. 6.3), the lower display shows the label SEtr (real set) and the upper display shows the actual working set point of the unit. Press the button again to display the domestic hot water set point SEtS (if the function is activated). 6.2 Modify the set point The modification of the set point is only possible for the current unit mode (chiller or heat pump) and for domestic hot water management if active. Press for at least 3 seconds. 3 seconds The display will show SetC or SetH depending on the operating mode in the lower line. The blinking value of the set set will be displayed in the upper line. IC200CX EVO user manual Use the keys and to modify the set point value. To confirm the new set point, press or wait for the time out to exit programming.
6.3 Double set point by digital input (optional) The double set point function (Energy Saving) allows to modify the regulation parameters via digital input (terminals 160). energy saving The Energy saving function is enabled when a digital input configured as “Energy saving” is active. When the Energy Saving function is active: • to the set point is applied an offset set by ES14 and ES16 parameters (different for cooling andheating); • the regulation differential is set by ES15 and ES17; standard differentials (St07 and St08 parameters) are not used if the Energy Saving is active If the Energy saving is active, the first pressure of button allows to read the set point set by parameter and second pressure allows to read the real set point (label Setr set modified by Energy saving finction). 6.4 Compensation of the set point based on the outside temperature (optional) The controller allows the working set point of the unit to be changed (compensated) automatically based on the outside air temperature measured by a probe installed on the machine.The summer set point and the winter set point can be compensated separately, whereas it is not possible to IC200CX EVO compensate the domestic hot water set point.For the settings of the dynamic set point, parameters user manual Sd01 to Sd06 must be changed and these can be accessed at user level (password 1) according to the settings indicated in the following sections. Please see the relevant section for the methods of accessing the parameters. Summer compensation In cooling mode, it is possible to increase/decrease the value of the working set point (parameter St01) by a value proportional to parameter Sd01. If parameter Sd01 assumes positive values, there will be an increase, and if it assumes negative values, there will be a decrease. The proportion of increase/decrease according to the outside air temperature value is controlled by a compensation start set point (parameter Sd03), and by the relevant differential (parameter Sd05) that can assume positive or negative values. The compensated value of the set point cannot exceed the limits of the working set point in chiller mode; it can therefore assume a value no lower than St02 and no higher than St03. When parameter Sd01=0 is set, the function is deactivated.

DOMESTIC HOT WATER PRODUCTION This configuration must be associated with a suitably sized boiler in which to store high temperature water. The boiler must have a well for insertion of the domestic hot water probe, placed at the top, through which the controller of the unit monitors the need to produce domestic hot water. The production of domestic hot water is indicated on the display by the symbol: 9.1 Units with a single userside exchanger For units with a single userside heat exchanger, the controller allows the sanitary hot water production function to be activated and managed with waterside valve. The following must be installed on the system: a 3way valve that diverts the flow of water to the user or sanitary hot water storage and a temperature probe that measures its value. The functionality allows the unit to control the temperature inside a storage tank for domestic hot water, through the domestic hot water probe, and to manage the 3way valve outside the unit. The priority is always for domestic hot water production. IC200CX EVO user manual Heat pump operation: the valve diverts the supply water to the system. The operating set is SetH (SetC if in chiller mode). Domestic hot water operation: the valve diverts the supply water towards the storage tank. The operating set is always SetS.
The priority is always for domestic hot water production. The heat pump normally operates on the system to meet the comfort requirements of the system, but when the temperature of the water inside the tank falls below a set threshold (set point SetS, chap. 6), the control manages domestic hot water production: • if the unit is operating as heat pump for heating, the 3way valve will be switched and the set point changed; • but if the unit is producing chilled water for air conditioning, the control switches the unit to heat pump mode, gives it the set point for domestic hot water and diverts the 3way valve to the appropriate position. Once the temperature inside the domestic hot water tank has reached the set value, the unit automatically returns to producing water for the heating and air conditioning system. 9.2 Units with a dedicated heat exchanger for domestic hot water (DWS) The unit in this setup has two heat exchangers: a system side one, for air conditioning and heating, and one dedicated exclusively to domestic water production. IC200CX EVO user manual On the system side heat exchanger, the unit can produce hot water or cold water to meet the heating and cooling requirements according to the seasons. On the heat exchanger dedicated to domestic hot water, the unit produces high temperature water to be sent to a storage tank outside the machine. This tank has been selected and sized according to the requirements of the system. Depending on the season, the unit works with different modes: the change through the various operating modes (within the season) is carried out automatically through the reading of the temperature probes and the set points. Switching times and logics have been designed to ensure the maximum efficiency and reliability of the system. This configuration must be associated with a suitably sized boiler in which to store high temperature water. The boiler must have a well for insertion of the domestic hot water probe, placed at the top, through which the controller of the unit monitors the need to produce domestic hot water.
9.3 Digital input for domestic hot water production only If the digital input configured as “Enabling of domestic hot water production only” (terminals 4001) is active, the controller is enabled for domestic hot water production only; thermoregulation for the production of hot or chilled water is disabled. sanitary only If the digital input is active, the unit can be switched on or put in standby by pressing button or (when switching off, the button pressed depends on the mode that was active when the digital input for domestic hot water production only was activated). When the digital input for domestic hot water production only is active the lower display shows the label “OSA” (Only SAnitary). 9.4 Digital input for domestic hot water double set point (option) IC200CX EVO The controller allows the domestic hot water working set point to be changed based on activation/ user manual deactivation of a suitably configured digital input (terminals 6101). double set sanitary When the value is active: • an offset of the value of parameter ES32 is applied to the DHW set point (parameter ES32 can assume positive or negative values, it can therefore assume a value no lower than FS05 and no higher than FS06); • the connection/disconnection differential of the compressors assumes the value ES33 ...
9.5 Antilegionella function (optional) The controller manages a weekly antilegionella cycle with the use of only electric heaters outside the unit; the compressors will remain switched off during the cycle. The antilegionella function can be activated by setting parameter FS12=1, and setting the day of activation (parameter FS18) and the start time (parameter FS17). To disable the function, set parameter FS12=0. The function is active with machine ON. If the antilegionella cycle request occurs while the machine is off, when it is next switched on, the controller will wait until the next weekly request time to immediately activate the antilegionella cycle. The function must remain active for the minimum time set on parameter FS19 (active from when the domestic hot water temperature reaches the antilegionella set point) and can last for a maximum time of FS29 minutes (the maximum operating time has priority over the minimum operating time; if the maximum time expires before the minimum time, the function will be exited). When the antilegionella cycle starts, all the heaters will be switched on to bring the water to set point; once the set point has been met, the heaters are switched off on reaching set point FS14+FS20. The antilegionella cycle is active for the minimum time FS19; during this time, the heaters regulate on the antilegionella set point FS14 and with control band FS04. During this procedure, the lower display will indicate the "LEG" label. IC200CX EVO user manual If the clock has an error, the function is disabled. Once this procedure has been completed, the controller will go back in domestic hot water production mode or normal thermoregulation mode.

In case of use of compressors with partialisations, each partialisation is seen as a step and the proportional band is divided by the total number of steps. The activation of the compressors respects the safety timing of the same (minimum ON time, minimum OFF time, minimum time between two starts of the same compressor, minimum time between the switching ON of two compressors, etc.).

11.2 Compressors management during domestic hot water production The regulation takes place on the set point for the production of domestic hot water (DHW) and with a proportional band that can be set by parameter (grouping of parameters FS); with the domestic hot water function active, the led of the domestic hot water mode and the led of the working mode (cooling or heating) are displayed. Compressor regulator diagram in DHW mode • FS03 Set point DHW, also accessible by key , SetS • FS04 DHW proportional band All’abbassarsi della temperatura dell’acqua sanitaria l’accensione dei compressori avviene in modo IC200CX EVO proporzionale rispetto al set point ACS. When the domestic hot water temperature decreases, the user manual compressors are switched on proportionally to the DHW set point. At the moment in which there is demand for domestic hot water production, an FS09 minute counter is active which determines the maximum time for reaching the domestic hot water setpoint; after this time all the compressors are inserted (if they were not already inserted). In case of an error of domestic hot water probe the DHW function is inhibited; the unit will however work normally in cooling or heating. If during the production of domestic hot water the main thermoregulation (main exchanger input probe) goes into error, there is no blockage of the unit but the cooling or heating thermoregulation will be disabled and DHW water production will remain active.
11.3 Water pump, function pulse Per impostazione predefinita l'accensione della pompa dell’acqua dipende dallo stato del dispositivo: • Dispositivo spento pompa acqua spenta • Dispositivo acceso in riscaldamento o raffrescamento pompa acqua accesa Alla prima accensione della pompa dell’acqua, i compressori sono accesi solo se è trascorso il tempo impostato in CO17 dall'accensione della pompa. Posizionando l’unità in standsby o OFF remoto la pompa dell’acqua si spegne dopo il tempo impostato nel parametro CO18. La pompa è comunque spenta se in caso di allarme termica pompa acqua o in caso di allarme flussostato. Function pulse If the pump is off (due to thermoregulation or due to unit in Standby/ OFF), the controller, if correctly parametrised, can carry out periodic switchons of the userside pump to move the water inside the pipes and measure the control temperature or to prevent pump shutdown due to prolonged inactivity. To activate the function, set parameter CO16 = 2 (pump operation when requested by the compressor). When the unit is on, on reaching the set point, the controller will switch off the water pump and start it again at regular intervals for a sufficient time to measure its actual temperature. If the controller verifies that the unit is still in set point, it will switch off the pump again. If it does not, it will activate the compressor, and the pump will run continuously until the next time the set point is reached. When the unit is started, if there is no control request, the periodic switchon cycle of the water pump IC200CX EVO will be activated. user manual • CO69 pump switchon time (in multiples of 10 seconds) • CO67 pump switchoff time (in multiples of 10 minutes) If the unit is off, periodic switchons will be carried out to move the water inside the pipes to prevent pump shutdown due to prolonged inactivity. • CO69 pump switchon time (in multiples of 10 seconds) • CO68 pump switchoff time (in multiples of 10 hours)

11.5 Auxiliary heat source function The controller manages an external source that can be used as a supplement or backup to the heat pump when the outside air temperature is particularly harsh. The supplement/backup mode depends on the selection of parameter Ar11. To deactivate the function, set parameter Ar11 = 0 (level Pr2). The external source is switched off: • with a flow switch alarm active; • with evaporator pump overload protection alarm active; in this case, the boiler heaters are activated only by the antifreeze set point for exchanger protection. Supplement function To activate the function, set parameter Ar11 = 1. During operation, when the air temperature measured by the outside air probe falls below the outside set point value Ar12, counting of the delay time Ar14 begins. If, during counting of time Ar14, the outside air temperature rises above the value set in parameter Ar12 + differential Ar13, the function is cancelled and time Ar14 is reloaded. Diagram of consent to activation of the auxiliary source and the compressors based on the outside air temperature. IC200CX EVO user manual If, after time Ar14, the outside air temperature remains below set point Ar12 and the water temperature measured by the thermoregulation probe is lower than set point value Ar17, the heat source is enabled. With supplement function enabled (outside air temperature below value Ar12), if the outside air temperature falls below set point Ar19, the compressors are switched off. The compressors are switched on again if the outside air temperature returns above set point Ar19 + control band Ar20. When set point Ar17 + control band Ar18 is reached, the external source is switched off.
