This function is available only if the system is fitted with a
technical water storage tank (buffer) for heating and/or cooling.
– "Buffer activation": allows to enable/disable the
buffer charge.
– "Buffer comfort setpoint heating": sets the desired
buffer charge temperature in heating mode for the
comfort slot.
– "Reduced Setpoint heating": sets the desired buffer
charge temperature in heating mode for the reduced
slot.
– "Buffer comfort setpoint cooling": sets the desired
buffer charge temperature in cooling mode for the
comfort slot.
– "Reduced Setpoint cooling": sets the desired buffer
charge temperature in cooling mode for the reduced
slot.
– "Buffer setpoint mode": sets the buffer charge mode.
– "Fixed": the buffer charge temperature is defined
in the parameters shown above.
– "Variable": the buffer charge temperature is
calculated according to the automatic temperature
control function (if active).
3.11.5 Heat Pump
This menu is available only if a heat pump with the heating/
cooling functions is installed. For further information, see the
product manual.

– "Quiet mode": the following settings allow for
reducing the noise level of the heat pump by limiting
the compressor frequency.

Activating this function may reduce the
machine’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 auxiliary 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 failure
backup”): the secondary heat source is activated
only in case of a heat pump malfunction.
– "DHW 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 auxiliary heat source) of the heat pump
in DHW mode.
