Thank you very much for your reply. I am not able to get the house to a comfortable 21 degrees by changing heat curve settings. It’s either too hot or too cold. I have floor heating at ground floor and low temperature radiators in 1st floor bedrooms. I feel heatpump is running too many hours using too much electricity hence wanted to switch to room temperature control. It should be possible with Vitotrol 200. The other challenge is that my installer is out of business and I contacted several other installation companies but they all say they don’t want to work on it because they didn’t install the heat pump. It seems I’m stuck☹️

Hello! My German is not great hence posting in English. Hope someone can help. I have a Vitocal222 with Vitotronic 200 integrated in the indoor unit located in garage. There is an outdoor temperature sensor and I can set desired temperature via Vitotronic. Currently heating happens based on difference between outdoor temperature and desired temperature set via Vitrotronic. I would like to change to: heating based on difference between actual room temperature and desired temperature. What is needed to make this change? Do I need to purchase another Vitronic 200 (or other component?) and place it in living room? Change in Vitocal 222 settings required? Thank you & best regards
