I have a Honeywell V8043E zone valve with an RA89A relay for the Beacon Morris HBB048 heating unit. The termostat is a Honeywell T87. Does anyone have a wiring diagram to this type of a system? I just can't get the entire system to synchronize.
Perhaps you could Google Honeywell and get a wiring diagram. I have some limited hydronic experience and even more Honeywell but, I'm sorry, I can't help in this case.
