Any HVAC guys in here? I have an old mercury thermostat. Flair 3 wire SPDT an I want to hook up this LUX programmable thermostat. Everything including the manual says the existing is usually lettered, but the Flair one is numbered - red - 4, white - 5, & green - 6.
I'm thinking I put the RED wire to one of the jumpered "R" terminals on the new thermostat, the WHITE wire to the "W" terminal and the GREEN wire to the "G" terminal. Correct?
