I have a model of central control Drayton htg DP1, the digital display has disappeared, and therefore my heating?
does not. Does anyone know what the problem might be? Thank you in advance. Thank you! It's embarrassing – sparky came round and simply lit the s / f spur my 18mth old daughter had died! I should have known – worked for an electrical wholesalers for 4 years! Do'h!
Usually, if the display fades the timer still works, it looks like you may have lost power and backup battery (if any) has burst? Check that the fuse is ok, it can be in unity on the next connection to the controller. Otherwise there may be a small reset button back
