Commissioning 1.5.5

Commissioning 1.5.5 External temperature correction Compensation of the temperature reading of the external sensor. 1.6 WATER CIRCULATION 1.6.0 CH pump prerun time Defines the pre-circulation time of the primary circulation pump to detect the presence of flow in the heating circuit. 1.6.1 Time for prerun new attempt Defines the stand-by time of the circulation pump between successive pre-circulation attempts. 1.6.2 CH pump overrun Post-circulation time. 1.6.3 Pump speed control Press the selector . Turn the selector to choose the desired item. Select the circulation pump speed: 0 Low speed 1 High speed 2 Modulating Press the selector to confirm. 1.6.4 Antifreeze HP circulator control Press the selector . Turn the selector to choose the desired item. Select the circulation pump speed during the heat pump anti-frost cycle: 0 Low speed 1 Med speed 2 High speed Press the selector to confirm. 1.7 HEATING CYCLE 1.7.1 Boost Time Defines the delay with which the water delivery set-point during heating is increased in AUTO mode. Intervenes only when the temperature control is active and set to “Devices ON/OFF” (see parameters 4.2.1 Thermoregulation/5.2.1 Thermoregulation/6.2.1). Defines the delay with which the delivery set-point temperature is increased by 4°C (up to maximum 12°C). If the value is 0 the function is not active. 1.7.2 FlowT HP Offset Defines the value in °C to be added to the delivery set-point temperature of the heat pump to offset the heat losses along the hydraulic connections between the outdoor unit and the hydraulic module. 1.8 COOLING 1.8.0 Cooling mode activation Press the selector . Turn the selector to choose the desired item. 0 Provisioned - Not active. 1 Active. Press the selector to confirm. 1.8.2 Cooling FlowT HP Offset Defines the value in °C to be subtracted from the delivery setpoint temperature of the heat pump to offset the heat losses along the hydraulic connections between the outdoor unit and the hydraulic module. 1.8.3 Humidity Control Threshold Define the Threshold to activate the Humidity Alarm if at least one zone reports a humidity over the value. Defines the humidity percentage value beyond which the humidistat alarm will be generated (see Par. 1.2.0 AUX output 1). 1.8.4 Humidity Control Hysteresis Define the Hysteresis to de-activate the Humidity Alarm if zones report a humidity under the value – hysteresis. Defines the hysteresis percentage value for resetting the humidistat alarm (see Par. 1.2.0 AUX output 1 - 1.8.3 Humidity Control Threshold). 42 / EN

Commissioning 1.9 DHW CYCLE 1.9.0 DHW comfort setpoint temp. Defines the comfort DHW set-point temperature. 1.9.1 DHW reduced setpoint temp. Defines the reduced DHW set-point temperature. 1.9.2 Comfort Function Press the selector . Turn the selector to choose the desired item. Configures the domestic hot water production mode as follows: 0 Disabled. 1 Timer based (starts the comfort function for time periods that can be adjusted according to the DHW time schedule). 2 Always active. Press the selector to confirm. 1.9.3 DHW operation mode Press the selector . Turn the selector to choose the desired item. 0 Standard. 1 Green. NOTE: uses only the heat pump in the periods configured with the domestic water auxiliary time schedule. 2 HC - HP. NOTE: the DHW storage tank is heated only by the heat pump when the EDF input is enabled (see Par. 1.1.0 HV input 1 (input configurable to 230 V)) and switches to 230 V (electricity off-peak hours). 3 HC - HP 40. NOTE: function similar to HC - HP, during electricity peak hours (EDF input = 0 V) the hot water storage tank is heated to 40°C. Press the selector to confirm. 1.9.5 Max HP charging time Defines the filling time, carried out only with the heat pump, after which the auxiliary integration sources are switched on when there is no sensor in the calorifier but only the thermostat (Par. 1.0.2 Tank management = 2). 1.9.6 Thermal cleanse function Press the selector . Turn the selector to choose the desired item. 0 OFF. 1 ON. NOTE: when the function is enabled, the DHW calorifier is heated and maintained at 60°C for one hour starting from the function start time (see Par. 1.9.7 Thermal Cleanse start time [hh:mm]), only if there is a calorifier sensor (Par. 1.0.2 Tank management = 1). The operation is repeated after a time period defined by Par. 1.9.8 Thermal Cleanse Cycle frequency. Press the selector to confirm. 1.9.7 Thermal Cleanse start time [hh:mm] Defines the start time of the DHW tank sanitisation function. NOTE: when the DHW HC - HP or HC - HP 40 production mode is used (Par. 1.9.3 DHW operation mode = 2/3), if the function activation time falls within electricity peak hours (EDF input = 0 V), the thermal sanitisation cycle does not start but is postponed to the following day. 1.9.8 Thermal Cleanse Cycle frequency Sets the period of time after which the DHW tank sanitisation function is repeated. 1.10 MANUAL MODE - 1 1.10.0 Manual mode activation Manual activation of the system components (circulation pumps, diverter valves, heating elements, etc.). Press the selector . Turn the selector to choose the desired item. 0 OFF. 1 ON. Press the selector to confirm. 1.10.1 HP circulator control Press the selector . Turn the selector to choose the desired item. 0 OFF. 1 Low speed. 2 High speed. Press the selector to confirm. 43 / EN
