This conguration is used for heating buildings in conjunction with air heaters. The
room temperature is captured by a sensor and the fan, the heating circuit pump and
the heat source are switched on or off depending on demand.
If the temperature deviation (set room temperature to actual room temperature) is low,
the fan is operated in stage 1. If the temperature deviation is greater, it is switched to
stage 2.
