I have a question I feel silly asking, I am currently rewiring a boiler. Its a auto mag system that was in need of a redo. We are putting in erie two wire zone valves, honeywell t-stats in two zones and lux in the other two. I have run an individual wire from each t-stat down into the relay. The zone valves are quite a distance away and it would be really nice to run a 18-6 over and pick them all up on one wire. I have done it on the thermostat side, but on the zone valve side I got worried. Can I tie one wire from each zone valve to one common wire, and then the other zone valve wire to one of the other five wires. Should I jumper from zone to zone in the relay, or is it sufficient to just hook one up?? I got worried about the two transformers, does each one control three zones or are they wired together to power all the zones. I have always run a wire to each zone valve, but on this job it would be really nice to reduce the number of wires. I know I need to jumper the third and fourth terminal for the two wire zone valves, and was going to jumper between each zone the wire that is tied to all the zone valves. I hope this makes sense???? Thanks for any help, this place needs it. The power vent went out under a deck with bushes inches away, they had to silicone the windows shut to keep from choking on oil fumes. 85 feet of oil line, on a one pipe 3/8 line. Its a buderus 115 that maintains temperature, and it maintains the high limit!!!!! The previous home owner just shut it off when all the zones were warm. Who ever put this in should be forced to live in this place for a winter.
