▶ Select how long the compressor should be on or off in heating mode.
Higher set values result in fewer compressor starts and stops, which
achieves higher economy. However, more pronounced temperature
fluctuations in the heating system may result than with lower values.

▶ Set how much a 1 K ( °C) difference in room temperature should
influence the set point value for the flow temperature.
Example: at a 2 K ( °C) deviation from the set room temperature, the
set point value for the flow temperature is changed by 6 K ( °C) (2 K
deviation * factor 3 = 6 K).
The menu is displayed only if a room controller is installed.

Optimised operation
This means that the control unit is only controlled by the flow set point
value ( Chapter 20.1.1), without programmed changes during the
day. Optimised operation provides the best comfort and energy savings
in the vast majority of cases.
