Hi,
Suddenly developed a problem with my CH. I have a modern conventional system installed about 4 years ago with Worcester Bosch Suprima HE boiler and Horstmann controls:
centaurplus c27 control panel
HRT 2 room thermostat
Z322? motorised valve
Hot water works normally with pump operating and boiler firing but when system is calling for heat (control panel and therm lights on)the boiler/pump do not operate. Any advice on what could be the problem would be much appreciated
