The heating/cooling system of the unit VW is described here.

The aim of the heating system is to provide heating energy for the winter. The heating is taken from the MTE grid. The heating is separated from the MTE grid by a heat exchanger. The aim of the cooling system is to cool the rooms in summer. The cooling is taken from the NTE grid. The cooling is separated from the NTE grid by a heat exchanger. The energy is dissipated via ceiling heating system and in the common rom via a floor heating system.

The system is switched on/off and via a fixed heating cooling limit. The system is operated via weather-compensated flow temperature control. The set point for the flow temperature is calculated as a function of the outdoor temperature via fixed an heating/cooling curve.

The room temperatures can be set individually for each heating circuit group via the room thermostats. For cooling, the controller is switched to cooling mode in summer.
