I have 2 C wires connected to each other in heat only baseboard
apartment heaters. Looking to install nest system, but don’t know what
to do with 2nd C wire.
I was able to get it to work. Only one C wire wasn't enough power to get
the thermostat to turn on. I had to wrap the C wires together, and put
into C terminal on back plate, and that was enough power. Been running
perfectly for weeks.
It’s low voltage wires coming out of it with Honeywell thermostat, I’m
pretty sure it’s still compatible. See if this link works!
