I built this for a friend who has a heater without a thermostat control, he was looking for a way to control a heater that came from the factory without thermostat. This design I came up with is working great.
The 115 volt is connected to the contacter and the transformer. The transformer sends 24 volts to the thermostat , when the thermostat calls for heat it sends a signal through the white wire to the contater telling it to pull in. This is allowing the 115 volts to go to the plug. This allows your heater to turn on by the thermostat.
