Viessmann 222 Heats to room temperature when cold outside, no matter what room temperature set at
Hello, We have a Viessmann 222 Central Heating System. When I set the room temp to be 18C, all is ok until the weather cools down. Then it brings the room up to 22C no matter what I do. I can set the room temp to 15, no matter, the radiators stay hot until it's 22C. I have looked through the settings to see if there's a weather setting I can adjust, but can't find it. Any feedback?
