1.4.2 Delay timer
Time required for starting the calculation of the DHW integra-
tion 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 el-
ement 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.
0
Absent.
1
Disabled: heating element present but disabled
2
Heating element only: 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 the attainment of the DHW set-point on
the calorifier. If there are any cooling/heating requests,
they are fulfilled in priority mode by the heat pump, ex-
cept below the temperature threshold defined by pa-
rameter 1.4.6.
1.4.6 DHW high priority temperature threshold
Defines the DHW calorifier temperature below which both the
heat pump and the heating element switch on together when
Par. 1.4.4 Heating element in DHW calorifier is set to 3 (Auxilia-
ry).

1.5.0 Min pressure
Indicates the pressure value below which the system stops.
1.5.1 Warning pressure
Indicates the pressure value below which it is advisable to fill
the system.
1.5.3 Text for HP disabling
The system excludes the heat pump in heating mode when
the outdoor temperature is higher than the value set.
1.5.4 Hp disabling out temp DHW
The system excludes the heat pump in DHW mode when the
outdoor temperature is higher than the value set.
1.5.5 External temperature correction
Compensation of the temperature reading of the external sen-
sor.
1.5.9 Filling pressure
Indicated pressure value for system filling.

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.

1.7.1 Boost Time
Defines the delay with which the water delivery set-point dur-
ing heating is increased in AUTO mode. Intervenes only with
temperature control active and when set to "Devices ON/OFF"
(see parameters 4.2.1/5.2.1/6.2.1).
Defines the delay with which the delivery set-point tempera-
ture 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.

1.8.2 Cooling FlowT HP Offset
Defines the value in °C to be subtracted from 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.
