Setting the heating curve. Left: setting the gradient by means of design temperature and
minimum outside temperature. Right: parallel offset possible by means of offset or set
room temperature.

Setting: design temperature 75 °C, minimum outside temperature – 10 °C (standard curve)

Parallel offset of standard curve by changing the 3 or by increasing the set room temperature

Parallel offset of the standard curve by changing the offset – 3 or by reducing the set room temperature
6.3.4 Setback modes (night setback)
There are a number of different setback 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 at night by constant
heating operation (pump runs constantly). A set room temperature for nighttime can be set. It is
at least 1 K lower than the set day temperature. The heating curve is calculated in accordance
with these details.
We recommend these settings for an underfloor heating system.
•
shut-down mode
: boiler and heating circuit pump are off, frost protection is active. The pump
only starts in frost protection mode.
This setting is not recommended if there is a risk that the building would cool down too severely.
