9.12 Setting the preheat phase for a gas-operated heat pump
(not in the UK)
If a gas-operated heat pump (Loganova GWP) is installed in your
heating system, we recommend that you set a preheat phase. This
setting has no effect on other devices.
During the preheat phase the heat pump unit preheats the heating
system without the peak load boiler. The continuous running of the
heat pump generally increases the overall efficiency and saves
more energy than a reduction in the room temperature.
The preheat phase starts at the preset time before the day mode
of the first heating circuit.
