wow, i can’t believe i overlooked the old heater being three phase. There were only two wires coming in to the old heater. Two, and a ground. However, i did notice that two legs of the heaters wiring were connected to one of the wires.

I wonder if the relay is working the other way around. I doubt I would have three phase service in a 1987 condo. Could the relay be converting to three phase? I’m familiar with rotary phase converters for machines, but this is certainly not one. I know the whole rotary thing is to get enough inertia going to overcome the initial friction loss of a machine though. So hmm…

Here is a copy of the specs inside my panel box.
