8.1.3 Valve exercising feature
To prevent valves from seizing after long periods of inactivity (e.g. cooling valve in
winter), the valves are operated from time to time. The valve actuators are operated in
such a way as to waste as little heating or cooling energy as possible.
The valve exercising function is triggered if the valve has been closed for ca. 91 hours
without interruption.

communication object:
