My home has two adjacent thermostats, each one controls a single 1000W 240V baseboard heater. The heaters themselves are on opposite walls of the dining room. I’d like to replace both thermostats with a single smart Mysa thermostat. I’ve already done the replacement in every other room of the house but I’d rather not have two thermostats here, and I can’t fit two Mysas side by side within this space anyway.
What’s the best way to do this in this spot? I think I should be able to wire the loads in parallel to a single thermostat but I’m not sure on the best way to do the wiring. Should I take the load wires out of the top box and move them into the bottom one? Or run a new jumper from one box to the other?
