I'm trying to wire a two stage exhaust fan for my greenhouse. The motor comes set up for 240v wiring and is to be controlled by a thermostat. I undertsand how to get the 240v from the panel, but can't seem to figure out the thermostat wiring diagram. What connects to what coming from the panel and going to the motor? See photos 1)thermostat wires and housing label, 2) thermostat wiring diagram. The motor has three terminals labeled high, low, and common.
