Is this the combi version?
The pump is controlled by the room stat, if you have no room stat then the pump will run all the time until the boiler turns off.
The burner will continue to go on and off with the returning water temperature
It's obvious you know nothing about this boiler. The pump is controlled by the flame detection device and I want my money back.
The pump runs before the boiler lights, so it cannot be controlled by the flame detection.
If it was run by the flame detection then the pump would only run when the boiler was firing, which it does not.
Do you have a room thermostat?
