Function
The heat pump prioritises hot water charging. The compressor
output is adjusted according to the outdoor temperature. The
circulation pump varies the flow to maintain a high charge
temperature.
When the water heater is full, the valves QM30 and QM31
switch to the heating system. The heat pump is then controlled
by a calculated set point value on the ow line. The compressor
varies the output according to the demand. The circulation
pump runs at a xed set speed.
If the compressor does not manage the entire heat demand, the
electric heater is activated if it is allowed by setting and the
heat shunted out on the ow line.
In the event of a cooling demand, the heat pump is controlled
by a calculated set point value on the ow line. The compressor
varies the output according to the demand. The charge pump
runs at a xed set speed.
