DOMESTIC HOT WATER
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
Configures the domestic hot water production mode as fol-
lows:
0
Excluded.
1
Timer-controlled (starts the comfort function for inter-
vals that can be adjusted according to the DHW sched-
ule programming).
2
Always active.
1.9.3 DHW operation mode
0
Standard.
1
GREEN.
NOTE: uses only the heat pump in the intervals configured
with the DHW auxiliary schedule programming function.
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) and switches to
230 V (electricity reduced-rate period).
3
HC - HP 40.
NOTE: a function similar to HC - HP, during full-rate electricity
supply (EDF input = 0 V) the hot water storage is heated to
40°C.
1.9.5 Max HP charging time
Defines the filling time, carried out only with the heat pump,
after which the integration heating elements are switched on
when there is no calorifier sensor, but the thermostat (Par. 1.0.2
= 2)
1.9.6 Thermal cleanse function
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), only if there is a calorifier sen-
sor (Par. 1.0.2 = 1). The operation is repeated after a period of
time defined by Par. 1.9.8.
NOTE 2: if the energy back-up sources are deactivated (Par.
1.4.1 = 0) or absent, the thermal sanitisation cycle might not be
completed owing to the heat pump's working limits.
1.9.7 Thermal Cleanse start time [hh:mm]
Defines the start time of the DHW calorifier sanitisation func-
tion.
NOTE: in case of DHW HC/HP or HC/HP 40 production mode
(Par. 1.9.3 = 2/3), if the function activation time falls within the
full-rate electricity period (EDF input = 0 V) the thermal saniti-
sation cycle does not start but is postponed to the following
day.

Sets the period of time after which the DHW calorifier sanitisa-
tion function is repeated.

by parameters 13.5.1 - 13.5.2.
1.11.5 Rating Cooling Mode

settable through Par. 13.5.1. The fans rotate at fixed speed set
by parameters 13.5.1 - 13.5.2.
1.11.6 Tank electric heater
Activates the heating element immersed in the calorifier in
DHW mode.

Activates deaeration of the system; the operation can last up
to 18 minutes.
1.12.1 Antiblocking function enable
