Air conditioning

The room air conditioning functions are based on the shell model from the VDI 3813 standard for room automation.

There is a timer program in the Building shell. This timer program describes the periods during which the rooms in the building are in Protection mode, Economy mode, Pre-Comfort or Comfort mode.

The operation modes of the buildings are also referred to as energy levels.

The longer the building is unoccupied, the further the energy level can be reduced.

If the building is not used for a very long time, it can be put into Protection mode.

In winter, the room temperature is reduced or increased to a frost protection setpoint and in summer to an overheating protection setpoint.

For longer regular periods of absence, e.g. at weekends or during the night, the Economy energy level is planned.

With the Pre-Comfort level, the setpoints are raised to such an extent that they can be reached for Comfort mode in the short term.

The setpoints for the Comfort level can be changed slightly if necessary using a local setpoint adjuster in the room.

The central generation and distribution of the room temperature setpoints for the entire building are contained in the building controller, see sketch ADS communication within the templates.
