5.3 Switching differential of the boiler temperature
Matching the burner to the type of boiler.
The boiler temperature is controlled by a 2-position controller for which a switching
differential can be set.
Setting range Unit Factory setting
0...20 °C (K) 8
The setting changes the switching differential of the boiler temperature control.
Entry:
Increase: Switching differential will become wider
Fewer burner starts and longer burner running times
Decrease: Switching differential will become smaller
More burner starts and shorter burner running times
With 2-position control, heat is produced at certain intervals. The period of time during
which heat is delivered is dependent upon the boiler mass and the amount of water
contained in the boiler.
The greater the demand for heat, the longer the burner runs at a time.
