5.9 Auxiliary heating
In addition to the heating effect achieved using the refrigerant circuit, the controller can handle other sources of
heating such as electric heaters and a hot water coil with an OK signal to a boiler or a burner.
The logic featured in the controller is set up at the factory, based on the unit configuration.
The function to enable heating and the operating logics can be customised.
The parameters concerned are shown in the table.
