2056 Setpoint source heating
The controller enables a swimming pool to be heated
by the heat pump. An individual setpoint can be set
by means of parameter 2056, which appears when
the swimming pool function is activated by parameter
6046 being set to "Swimming pool release".

Switch-off temp max
If the flow or the return temperature exceeds the
maximum switch off temperature, the compressor will
be switched off.
Release integr electric flow
After the release of the 1st stage (K25), the controller
compares the temperature measured with the point of
engagement and forms an integral and includes a
possible deficit of heat. Once the value of the integral
reaches the maximum value (2882), the 2nd stage is
engaged (Stop K25, K26 regulates). The controller
continuously compares the temperature measured at
the point of engagement and new features to the
deficit of heat in the full release. When the full release
reaches the value set (2882), the 3rd stage of the
heater is triggered (K25 and K26 regulates fixed).
Flow elec. release at OT
The heater will be activated only if the attenuated
outdoor temperature is below the temperature set
here.
Warning:
If this setting is too low, there may be a feeling of
discomfort due to the fact that the heat pump is
unable to meet the heating requirements alone at low

Use of input H2 requires an extension to be

must be addressed as "module 1".
outdoor temperatures, and heaters are not switched
on.
Release above OT
The heat pump is released only when the composite
outside temperature lies above the value set here.
Below this outside temperature level, the amount of
heat required must be delivered by some other heat
source.
With electrical utility dock
This setting relates to input Ex4 (load-shedding or
peak day clearing) and allows the electric heaters to
be locked as follows:
•
Locked:
The heat pump and all electric heaters are locked,
both heat pump stages and the DHW tank electric
auxiliary.
Only the boiler backup, if installed, continues to
operate
•
Released
The heat pump operates and all electric heaters are
locked, both heat pump stages and the DHW tank
electric auxiliary.
The boiler backup, if installed, continues to operate.
