I have an RF towerstat which was installed 3 yrs ago and has been problem free until now. I recently pressed the reset button to clear all the progrrams and since then it has failed to function properly. inorder to activate the central heating in have to set the temp to 7dg and to turn off set the temp to 30deg. there is no control over the temp although it does display the room temp. Can anyone advise. i have read the instructions and followed the reset protocol but it does not cover or advise about the problem i am experiencing. many thanks
