For adjustment, see coding 04 on page 156.
Switching differential 4˚C / 7˚F (coding 04: 0)
Heat demand-dependent switching differential
ERB50 function (coding 0 : 1)
Subject to heat demand, values between 6 and 12˚C / 11 and 22 °F result.
ERB80 function (coding 04: 2)
Subject to heat demand, values between 6 and 20˚C / 11 to 36°F result.
The heat demand-dependent switching differential takes the boiler load into account. The switching differential, i.e. the
burner operating time, changes based on current heat demand.
