Heating circuit pump logic function (summer economy
control): Heating circuit pump switches off when out-
side temperature 1 K above selected value. Heating
circuit pump switches back on when outside tempera-
ture 1 K below selected value.

ture 25 °C
10 to 35 Heating limit adjustable from 10 to 35 °C in 1 °C incre-
