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.
