Burner switching hysteresis
Switching hysteresis 4 K (04:0)
Heat−demand dependent switching hysteresis (only with outside temp. sensor)
ERB50 function (04:1)
Subject to heat demand, values between 6 and 12 K result.
ERB80 function (04:2)
Subject to heat demand, values between 6 and 20 K result.
The heat demand−dependent switching hysteresis, therefore, takes the boiler
load into account.
The switching hysteresis, i.e. the burner operating time, is varied subject to
the current heat demand.
