Hello,
I hope some one can put light on this.
Glowworm ultimate 40ff heat only boiler on Y plan.
When call for heat boiler fire ups. Zone valve working.
Thermostat working.
But there is no power to the pump.
Boiler will cut off after few minutes, because of no circulation.
Check all the wiring, they all okay.
If you have any suggestions.
Thanks
