Before going on holiday I switched off water and heating. Since coming Bach I cannot get central heating system to switch back on. I have a SUPRIMA HE boiler and a SUNVIC SELECT XL thermostat (which is not showing display). I have checked fuse and it is OK. "On" light is showing on boiler. No fault lights showing or flashing. Agh!
boiler wont fire up and thermostat display blank
