Hi , what temperature do you have set at 20.30?
Ok , youbknoiw there is no on and offs , only temperature changes?
Hi , do you have a sun and moon symbol on the stat?
I know I am probably asking things that you may know or have tried , but for me to help I need to run through these things,
Can you verify what temperatures you have for both, please
Ok , well do you want to double check later and we can continue then ?
Ok , well then the temperature shoulnt be going up to 30. These p4og room stats Congo faulty eventually . I can only recommend replacement , as unless you are an electronics engineer there are no repairable parts.
