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.
- Adaptive learning ensures the wanted temperature at the wanted time (here 20 °C at 07:00).

- Adaptive learning is sensitive to large, rapid temperature changes.
Winter: Long warm up time Spring/fall: Short warm up time
