bled (only for weather-compensa-

i.e. at a variably adjustable value be-
tween 5 and 35 °C, plus 1 °C, the
burner and heating circuit pump stop
and the mixer closes. The basis for
this is the adjusted outside tempera-
ture. The adjusted outside tempera-
ture is based on the actual outside
temperature and a time constant,
which takes into account the cooling
down of an average building.
