It can be defined whether or not the condenser pump shall be put into operation when
frost protection for the plant is activated.
Off
The condenser pump does not run when frost protection for the plant is activated.
On
The condenser pump runs when frost protection for the plant is activated.
This defines whether the pump shall run when there is a valid request or only when the
compressor is in operation.
Temperature request
The condenser pump starts running as soon as there is a valid temperature request.
Parallel compressor operation
The condenser pump runs when at least one compressor is in operation.
The condenser pump also runs when the electric immersion heater installed in the flow
is in operation.
In the case of an active separate DHW circuit and DHW controlling element Q3 =
charging pump (5731), the condenser pump does not operate.
The condenser pump can also be activated by the following functions:
•
Frost protection for the plant
•
Frost protection for the heat pump
•
Storage tank recooling
•
Passive cooling
Prior to starting the compressor, the condenser pump must be activated, enabling the
sensors to acquire the correct temperature.
When the compressor is switched off, the condenser pump continues to run for the set
overrun time.
In the event of a heat pump fault, the condenser pump is deactivated until the fault is
corrected.
However, if activated, frost protection for the plant, the heat pump or the electric
immersion heater K25/K26 can still put the condenser pump into operation.
