I've got a Honeywell L8148A primary boiler control thatseems like the switching relay is bad.
I think this relay only turns on the burner and circulator for on zone of my 4 zone system.
All 3 of the other zones work fine. If I turn upthe thermostat of any of the other zone and
force the relay by hand, the circulator pump will turn on for the "bad" zone. I'm thinking I
can just pull the board and replace the relay rather than buying the whole control.
Does anyone know where I might find the part number of just the switching relay? I was able
to find info on the L8148A control at this site:
Thanks in advance, Tom
