can anyone help went to turn the heating on and on the control panel there is nothing showing got a number 13 but cant get anything to work
the power went off here a while back and have read it might be the backup battery that needs replacing or is there some kind of reset button inside the box.
also what kind of battery is in there i have not taken it apart yet
any help would be greatful
