Outdoor temperature dependent advance heating
Due to low outdoor temperatures, the controller starts heating before the time-of-use period
starts in rated operation. The Advance heating time uses a reference outdoor temperature of
–12 °C. The advance heating time is shortened when the outdoor temperature is higher.
The colder it is outside, the earlier the reduced operation is ended to ensure that the required
room temperature is reached at the start of the time-of-use period.
Note! During the advance heating phase, the

Delayed adaptation to the outdoor temperature
The calculated outdoor temperature is used to determine the flow temperature set point. The
heat response is delayed when the outdoor temperature either gets colder or warmer. If the
outdoor temperature varies by, for example, 10 °C within a very short period of time, the
calculated outdoor temperature is adapted to the actual outdoor temperature in small steps.
Assuming a Delay of 5 °C/h, the adaptation would take t
The delayed adaptation to the outdoor temperature helps avoid unnecessary overloads of
central heating stations in combination with either overheated buildings occurring, for exam-
ple, due to warm winds, or temporarily insufficient heating due to the outdoor sensor being
exposed to direct sunshine.
Note!
The described function can only be activated together with weather-compensated control.
