I've got a Dayton g73 garage heater that is currently hardwired to the 30A breaker. I would like to put in a wall mount thermostat since I can never seem to get the dial setting right and am constantly having to go over and adjust it.
My plan is to wire a 240V -> 24V transformer in parallel on the heater circuit, run the wire to a thermostat, which will switch a relay to open/close both legs of the circuit.
Will the extra current draw of the relay and thermostat work? The heater is setup for full wattage, which I think draws close to 30A (I haven't put a meter on it)
Do I need a NO or NC relay? Ie, is the 24V power from the thermostat on when the room is too cold or too hot?
Anything else I need to know?
Thanks in advance!
