For some reason my living room was 30 degrees in the morning. No matter what I tried on the EasyControl in the living room it wouldn’t go down.

I factory reset my EasyControl (loosing all my energy usage data along the way…), reset all my radiator fobs. Reinstalled them, set up the schedules from scratch… A lot of work.

And then my daughters bedroom all of a sudden went to 30 degrees…

In the end it was corrosion on one of the fobs that caused the plus button to be triggered continuously. Once I replaced the fob with a spare one the problem went awway.
