Why are my radiators heating doing night set-back periods?

The reason might be, that Adaptive learning is enabled.

The adaptive learning function (Forecast) ensures that the comfort temperature is reached at set time. The warm up time is continuously adjusted according to seasonal temperature changes.

1. Adaptive learning ensures the wanted temperature at the wanted time (here 20 °C at 07:00).
2. Adaptive learning uses data from the previous 7 days to be able to reach the correct temperature at the right time.
3. Adaptive learning is sensitive to large, rapid temperature changes.

 

 Winter: Long warm up time                                        Spring/fall: Short warm up time

 

In case you would like to disable this feature, it can be done in following way:

Swipe to the left from the App home screen ->

Go to settings ->

Advanced settings ->

Adaptive learning OFF

 

If you turn Adaptive learning OFF, heating will be running according to set schedule.
