Larry , I believe if the phases are aligned (same bus bar on the panel) there is no 220 present...And Im not arguing electricity, I will fully admit my knowledge of elec. will make your hair stand on end :o

If he uses a double pole,line voltage t-stat, he will be able to use the same power source that is feeding the existing boiler/controls. One side will feed the pump and one side feed the modine. The 120v is jumper end between the two sides to feed each side. This was keeps the modine from coming on any time the house zone calls. It also prevents any " STUPID" wiring issues like feeding the controller with 240 or having someone get shocked because there are two sources of power when there is only suppose to be one. Yes the controller would burn up first and last I knew, controllers were three times the cost of a circ pump, or more.

C1 C2 are wired to an outlet mounted below the aquastat. B1 B2 are wired to a second outlet. The circulator and stoker are plugged in.

This way I can unplug the circulator and/or stoker motor from the aquastat when i want and plug directly into the outlet before my main shut off.

I did this so I could manually run the stoker motor and circulator in case other electronics (timer, aquastat, thermostat, zone valve) fail.

I didn't even think about using a double pole. That makes a lot of sense now.

Could use a double pole switch too
