Temperature differential heating
Parameter
■ 7003
The heating limit temperature defines
the value of the outside temperature,
below which central heating commen-
ces.
The heating limit temperature is the
result of the selected set room tempera-
ture 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 adjus-
ted outside temperature drops below
16 °C (heating limit temperature).
If the adjusted outside temperature
exceeds 18 °C, central heating stops
(because of the specified hysteresis of
2 K).
