I'm using a Nest Thermostat to power baseboard heaters (240VAC).
I have 4 wires that I have access to:
- 2 wires: Red/Black from a transformer which outputs 24VAC
- 2 wires: 24VAC from a thermostat RELAY (Honeywell R841C1169)
I thought initially that the two wires from the thermostat relay connect to W1 and RH.
But then I wasn't sure how to do the common wire.
Then I thought about the C wire, and thought I could use a 24VAC transformer, but in my diagram, 2 hot wire were touching, and I wasn't sure if that was bad. Is it?
Somehow this doesn't seem good.
How can I get the common wire involved? I'm pretty sure the wires from the relay are OK, they just hookup to W1 and RH. But where do the wires from the 24VAC transformer go? One of them I'm pretty sure needs to go to the C wire, but where does that last wire go??
