Buffer setpoint mode
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).

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

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.
– 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.
