Hi
how is the high low setting controlled on my boiler?
long story but got water on the pump that blew it. replaced and if set to high the central heating and hot water works all ok. If set to low on hot water - the pump runs all the time.
If I go to the clylinder strap stat and turn this down, then as I do I can get the pump to go off / turn it up and on it comes again.
If I turn the high low setting to high - it all regulates as it should.
Thanks
