My Viessmann 100 UTA Room Thermostat ran out of battery recently and began flashing red. I change the battery after noticing the heating was on constantly.
After switching on and off the boiler (30 kw combi boiler) in attempt to reset the sync the timer does not appear to be communicating with the boiler. The heating is constantly on and the radiator is boiling hot, even though it is on it's lowest setting.
I also have another question, it maybe because it's -3 outside and a anti- freeze mechanism. But how on earth do I control this?
Please help, any advice or tips are greatly appreciated.
My heating bills are going to cost a bomb!
