i have a Gloworm Ultimate boiler which is controlled by a Landis and Staefa controller and room stat. ive not had my central heating on for a while but reguarly use my boiler for my hot water.
this evening i went to turn my central heating on and the boiler does not fire up. the room stat is calling for heat. switched the controller to my hot water and the boiler fires up straight away.
could it be a faulty controller or roomstat?
