I've got a Glow worm Ultimate 40FF and a couple of weeks ago I noticed that although it was set so that only the water was being heated, the radiators were getting hot too even though CH was set to off.
Having been away on holiday for 2 weeks I got back and reset the control panel and set the timers again. Now, whenever the water and heating are on at the same time their is a loud clicking at the boiler and the lights on the control panel in the air cupboard flash on and off when it clicks every couple of seconds.
I have a very limited knowledge of Boilers etc so any help would be most grateful.
Thanks
