– "Quiet mode": the following settings allow for reducing
the noise level of the heat pump by limiting the compres-
sor frequency.
a
Activating this function may reduce the ma-
chine’s performance.
– "Quiet mode activation HHP": enables/disables
the silent mode.
– "Quiet mode start time HHP [hh:mm]": sets
the time for the machine to start working in silent
mode.
– "Quiet mode end time HHP [hh:mm]": sets
the time for the machine to stop working in silent
mode.
– "CH aux heat source activation logic": the parameter
allows to choose when to activate the secondary heat
source (heating elements, if enabled or present, or an aux-
iliary heat source) of the heat pump in heating mode.
– In case of a heat pump malfunction and for heat
production integration (“Heat integr. and backup”):
the secondary heat source is activated to integrate
heating/DHW production and in case of a heat
pump malfunction.
– Only in case of a heat pump malfunction (“HP fail-
ure backup”): the secondary heat source is activat-
ed only in case of a heat pump malfunction.
– "DHW aux heat source activation logic": the parame-
ter allows to choose when to activate the secondary heat
source (heating elements, if enabled or present, or an aux-
iliary heat source) of the heat pump in DHW mode.
– "DHW operation mode": the parameter sets the DHW
production mode.
– "Standard": domestic hot water is produced us-
ing both the heat pump and the secondary heat-
ing source for integration.
– "Green Mode": the heating elements are exclud-
ed from the production of domestic hot water and
are activated only in case of a heat pump malfunc-
tion. Domestic hot water production follows the
auxiliary time scheduling.
– "HC - HP": domestic hot water production is only
allowed when the EDF signal is active and accord-
ing to the cheapest electricity rate. To configure
the EDF signal of the heat pump, see the product
manual.
– "HC - HP 40": domestic hot water production is
only allowed when the EDF signal is active; when
the signal is not active, the DHW cylinder is main-
tained at the minimum temperature of 40°C. To
configure the EDF signal of the heat pump, see the
product manual.
