Precondition: Cooling function is active.
The cooling limit temperature defines the
outside temperature, exceeding of which
triggers the cooling function.
The cooling limit temperature is the
result of the selected set room tempera-

Example:
The selected set room temperature is
20 °C; the temperature entered under
"Temp. diff. cooling" is 4,0 K.
The cooling function starts if the adjusted
outside temperature exceeds 24 °C
(cooling limit temperature).
If the outside temperature drops below
23 °C, the cooling function stops
(because of the specified hysteresis of
1 K).
