home heating?
hi my Halstead hero 60 when the time clock /thermostat call for heat the Boiler fires up, but when it cuts out on temperature it does not fire up again on demand , but the Fan runs.
then I have to turn the Boiler control Knob to to the off position and on again, then it fires up. any advise
Thanks John
