Line no. Programming line
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".

Overrun time cond pump
When the compressor is switched off, the condenser
pump continues to run for the set overrun time.
Compressor off time min
For the same reason, the compressor remains
switched off for the minimum period of time set here.
Switch-off temperature maximum if the flow or the
return temperature exceeds the maximum switch-off
temperature, the compressor will be switched off.The
heat pump is switched
temperature at both sensors has dropped by the
"Switching diff return temp" below the maximum
switch-off temperature and the minimum off time has
elapsed.
Switch-off temp max
If the flow or the return temperature exceeds the
maximum switch off temperature, the compressor will
be switched off.
Locking time stage 2
When compressor is restarted, the time which keeps
minimum capacity can be adjusted. Efficiency
becomes better; however, the time of rising capacity
becomes long.

on again when the
Use of input H33 requires an extension to be
connected to the control.
Compressor mod run time
Compressor mod run time means the time of
compressor frequency indication changed from
minimum to maximum. If this setting value changes to
small, compressor frequency changes more quickly.
Warning :
This setting value is too small, the efficiency is
decreased due to the compressor frequency changes
frequently.
Release integr electric flow
After the release of the 1st stage (heater 1:on, heater
2:off), 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 (heater 1:off, heater
2:control). 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
(heater 1:fixed on, heater 2:control).
