Temperature differential heating
Parameter
7003
The heating limit temperature defines
the value of the outside temperature
below which central heating com-
mences.
The heating limit temperature is the
result of the selected set room tem-
perature less the value entered under
"Temp. diff. heating".
Example:
The selected set room temperature is
20 °C; the temperature entered under
"Temp. diff. heating" is 4.0 K.
Central heating commences if the
adjusted outside temperature drops
below 16 °C (heating limit tempera-
ture).
