Commissioning 1.2.5 AUX

Commissioning 1.2.5 AUX P2 circulator setting Press the selector . Turn the selector to choose the desired item. 0 Auxiliary circulator: the circulation pump simultaneously follows the switching on/off of the P1 primary circulation pump. 1 Cooling circulator: activates when the cooling mode is selected and the heating request is active. 2 Buffer circulator: activates when the cooling mode is selected and the heating request is active. 3 DHW circulator: the circulation pump is activated depending on the auxiliary time schedule and when a thermal sanitisation cycle is in progress. 4 Time programmed output: the output is activated depending on the auxiliary schedule programming 5 De-stratification pump: the de-stratification pump is activated when a thermal sanitisation cycle is in progress Press the selector to confirm. 1.2.6 Pro-Tech anode active Indicates the presence of the impressed-current anode on the DHW tank. Press the selector . Turn the selector to choose the desired item. 0 OFF. 1 ON. Press the selector to confirm. 1.3 CH SECONDARY HEAT SOURCE ACTIVATION 1.3.0 CH aux heat source activation logic Press the selector . Turn the selector to choose the desired item. 0 Heat integr. and backup: during heating cycles the auxiliary sources (output auxiliary contacts or heating elements) can activate both in integration mode together with the heat pump and also if the heat pump is unavailable. 1 HP failure backup: during heating cycles the auxiliary sources (output auxiliary contacts or heating elements) can activate only if the heat pump is unavailable. Press the selector to confirm. 1.3.2 ECO / COMFORT Defines the start-up delay of the integration heating elements from most economical/ecological (longer delay time) to most comfortable (shorter delay time). Press the selector . Turn the selector to choose the desired item. 0 Eco Plus: 1 Eco: 2 Medium: 3 Comfort: 4 Comfort Plus: 5 Customizable: Press the selector to confirm. 1.3.3 Delay timer The parameter is used when 1.3.2 ECO / COMFORT = 5 (custom). Defines the minutes to wait before the integration sources get involved by the Energy Manager. 1.3.4 Release integral threshold The parameter is used when 1.3.2 ECO / COMFORT = 5 (custom). Defines the threshold for the release integral used by the energy manager to activate the integration sources. 1.3.5 Reset integral threshold The parameter is used when 1.3.2 ECO / COMFORT = 5 (custom). Defines the threshold for the reset integral used by the energy manager to deactivate the integration sources. 40 / EN

Commissioning 1.4 DHW SECONDARY HEAT SOURCE ACTIVATION 1.4.0 DHW aux heat source activation logic Press the selector . Turn the selector to choose the desired item. 0 Heat integr. and backup: during DHW cycles the auxiliary sources (output auxiliary contacts or heating elements) can activate both in integration mode together with the heat pump and also if the heat pump is unavailable. 1 HP failure backup: during DHW cycles the auxiliary sources (output auxiliary contacts or heating elements) can activate only if the heat pump is unavailable. Press the selector to confirm. 1.4.2 Delay timer Time required for starting the calculation of the DHW integration with the auxiliary sources or with the heating elements. 1.4.3 Release integral threshold Activation threshold for DHW integration expressed in °C x min. 1.4.4 Tank electric heater Selection of the operating logic of the integration heating element immersed in the DHW calorifier. The use of this heating element precludes the use of any heating elements present in the hydraulic module in DHW mode. Press the selector . Turn the selector to choose the desired item. 0 Absent. 1 Disabled: heating element present but disabled. 2 Alone electric heater: the heat pump is not used in DHW mode. Only the heating element heats the DHW calorifier. 3 Auxiliary: The heat pump and heating element both contribute to reaching the DHW set-point on the calorifier. If there are any cooling/heating requests, they are fulfilled in priority mode by the heat pump, except below the temperature threshold defined by parameter 1.4.6 DHW high priority temp. threshold . Press the selector to confirm. 1.4.6 DHW high priority temp. threshold Defines the DHW calorifier temperature below which both the heat pump and the heating element switch on together when Par. 1.4.4 Tank electric heater Heating element in DHW calorifier is set to 3 (Auxiliary). Press the selector . Turn the selector to choose the desired item. Press the selector to confirm. 1.5 ENERGY MANAGER PARAMETER 1 1.5.2 Text for boiler disabling Used only for hybrid system: the system excludes the Boiler when the outdoor temperature is higher than the value set. 1.5.3 Text for HP disabling The system excludes the heat pump in heating mode if the outdoor temperature is below the set value. 1.5.4 Hp disabling out temp DHW The system excludes the heat pump in domestic hot water mode if the outdoor temperature is below the set value. 41 / EN
