Any help would be great
Worcester 9/14 cbi boiler
Honeywell st699 programmer
Honeywell room stat
Straight to the point, boiler not operating when heating required, have turned boiler on/off, re-set programmer, checked fuses/connections, all good.
Programmer heating light illuminates so bypassed/bridged room stat still no go, boiler silent, no fan no pump.
Hot water is fine btw.
Possible PCB failure is my guess, I take it the PCB has seperate heating and hot water circuits?
Any suggestions welcome.
Thx
Andy.
