Fig. 7 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.

minA

Minimum outside temperature

Design temperature (flow temperature that should be achieved at min. outside temperature)

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

2 Setting: design temperature 75 °C, minimum outside temperature – 20 °C

3 Setting: design temperature 50 °C, minimum outside temperature – 10 °C

4 Setting: minimum flow temperature 35 °C

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

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

7 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.
