perature (Fig. 6, right). It can be advisable to set an offset if, for example, the room tem-
perature measured with a thermometer differs from the set target value.

Parallel shifting of base curve by changing the offset +3 or by increasing the target room temperature

Parallel shifting of base curve by changing the offset -3 or by reducing the target room temperature
6.3.4 Reduction modes (night setback)
There are a number of different reduction modes available, which allow night setback to
be adjusted to suit the differing needs of the user:
– Reduced operation: The rooms are maintained at a reasonable temperature by con-
stant heating operation (the heating circuit pump runs constantly). A target room tem-
perature for nighttime can be set. This must be at least 1 K lower than the daytime
target room temperature. The heating characteristics will be calculated in accordance
with this setting.
This setting is recommended for underfloor heating.
