A simple question, but so far I've not found a definitive answer:-
Some older boilers use a thermostatically controlled pump overrun switch built into the boiler thermostat.
They are generally factory set and not adjustable.
At what temperature should it switch?
I'm specifically referring to the Glowworm Fuelsaver MK2 boiler with a Ranco C77p0102 thermostat, but I imagine they are all set to operate at a similar temperature.
I suspect it should be 65degC.
Can anyone confirm this?
