Setting Explanations
Heating circuit pump logic function (summer economy
control):
Heating circuit pump switches off when outside tem-
perature is 1 K above selected value.
Heating circuit pump switches back on when outside
temperature is 1 K below selected value.
25 °C 25 Heating limit at outside temperature 25 °C
10 to 35 Heating limit adjustable from 10 to 35 °C
