Switching differential 4°C / 7°F
Switching differential heat demand-
controlled
ERB50 function
Values from 6 to 12°C / 11 to 22°F are
set, depending on the heat demand.
ERB80 function
Values from 6 to 20°C / 11 to 36°F are
set, depending on the heat demand.
The heat demand-controlled switching
differential takes into account the boiler
load. The switching differential, i.e. the
burner operating time, is varied in relation
to the actual heat demand.
