My Tado is set to 21 degrees, room is 25 degrees, radiator switches on
I seem to be having a problem in one of my rooms. We have one room with a lot of windows, so this room gets very hot in the afternoon. The radiator is set to 21 degrees during the day, because we use that space as an office. Now it happened twice that the room temperature is 23-25 degrees, and yet the tado says "heating to 21" and switches on the radiator. What's going on here? Anyone with a similar situation?
