booklet) the indoor unit must be set in "Stand-by".
The function can only be activated if the appliance is not under
alarm.
3.23 PUFFER IN PREHEATING FUNCTION
In the presence of an inertial storage tank heated by other sources
of heat, following a central heating demand, it is possible to pre-
vent the generators from being activated by using hot water co-
ming from the puffer
The function is activated by setting one of the relays of the relay
board at 4. (see P03, P04,P05).
The puffer function requires the puffer probe.
See the instruction sheet of the relay board for details and exam-
ples

3.24 NIGHT MODE FUNCTION

This function can be activated by setting the internal clock of the
appliance (parameters U021 and U022).
Activating the function allows you to reduce the compressor fre-
quency during the condensing unit operation in the time slot set
in the U012 and U013 parameters.
Make sure the additional power sources needed to meet potential
requirements that may present themselves during active opera-
tion are available (e.g. additional resistances).
3.25 SYSTEM SETPOINT CORRECTION
FUNCTION
In the presence of hydraulic disconnections on the system which
separate the appliance from the low temperature zone (zone 2), a
function can be activated which allows to meet the demands, by
correcting the appliance's setpoint.
The corrections can be made either in heating or cooling mode
only.
They are activated by setting the parameters P023 or P024 at a va-
lue > 0°C.
Following a demand, the correction begins after a time equal to
P021 and continues by 1°C every P022 minutes.
3.26 HEATING / COOLING SELECTOR
FUNCTION
It is possible to select the type of request, central heating or cooling
directly from an external selector (see Connection diagram (Fig.
8) (available from revision 2.0 of the P.C.B. firmware).
To use this command, the function in question must be enabled by
means of the parameter A39=ON.
To make the demand, select the type: central heating = open con-
tact, and cooling = closed contact, and close the contact of zone 1
room thermostat.
The remote devices cannot be used when the function is enabled,
except for the room thermostat of zone 1; even the demands of
other zones, 2 or 3, are disabled automatically
