QX2
No consideration is given to the locking time, if the heat
pump malfunctions or is locked, or if the supplementary
source must end DHW charging
Setting "- - -" can be used to deactivate the function.

DHW Tank Functions (with DHW kit or with
integrated DHW models)
DHW charging at the nominal setpoint temperature
(1610) always takes place in two stages. In the first stage,
only the heating pump heats the DHW tank The power
supplied during this time is at its peak Then, when the
heat pump is no longer able to supply enough heat to
reach the setpoint value, it switches on the DHW tank
auxiliary if authorised The auxiliary will be cut off when
charging is complete
While the DHW tank charging process via the electric
auxiliary is finishing, the heat pump resumes heating.

Switching differential

Charging time limitation
Switching differential :
If the DHW temperature is lower than the current setpoint
minus the differential set here, the DHW charging process
is launched
It ends when the temperature reaches the current
setpoint
Information:
Forced charging is triggered on the first DHW release
of the day
Charging is also launched when the DHW temperature
is within the differential, and as long as it is not less than
1K above the setpoint
Charging time limitation
During charging, the room heating may be stopped or
insufficient. Therefore it is often advisable to limit the
charging process timewise to enable heating
If "- - -" has been selected the charging time limitation will
be deactivated The DHW will be heated to the nominal
setpoint, even if the room heating has not received
enough power in the meantime
If a value between 10 and 600 is selected, charging will
be suspended after the time period set in minutes, and
will remain suspended over that time before resuming
The generator power remains available in the meantime
to heat the room This cycle is repeated until the DHW
nominal setpoint has been reached
Information:
When the room heating is stopped (summer mode,
economy function, etc ), DHW charging remains active,
regardless of the setting

Recooling collector
Recooling temp :
An activated "Recooling" function remains active until
the set recooling temperature in the DHW storage tank
is reached
Recooling collector :
When the collector is cold, surplus energy can be emitted
to the environment via the collector’s surfaces
