5.6.3.2 Setting the heating limits
Specifying the heating limits for the heating circuit
For each heating circuit, separate heating limits are
adjustable for heating mode (within the set heating
times) and reduced operation mode (outside the set
heating times).
If the current outside temperature exceeds the
configured heating temperature (for example 18 °C),
the heating circuit is switched off. The same applies to
reduced-temperature mode as soon as the outdoor
temperature exceeds the set heating limit.
If the outside temperature falls below the set
heating limit (for example: 18 °C), a hysteresis of
2 °C will be observed in order to avoid cycling the
heating circuit. Accordingly, the heating circuit will
switch on only once the outside temperature falls
below 16 °C (=18 °C - 2 °C).
The heating limits are adjusted through the settings of
the heating circuit (
button) in the heating curve
menu ( button).
Setting heating limits for heating mode
1. Change the selector switch to the heating mode
position ( ).
Use the arrow keys to reduce parameter [Heating
threshold], so that the heating circuit in heating
mode switches off at a lower outside temperature,
or increase the value.

Setting heating limits for the reduced operation
mode
1. Change the selector switch to the reduced
operation mode position ( ).
Use the arrow keys to reduce parameter [Heating
threshold], so that the heating circuit in reduced
operation mode switches off at a lower outside
temperature, or increase the value.
At settings below 0 °C, there is a risk of
freezing.
