WEBAug 14, 2022 · I would advise against installing a standard thermostat. You don’t have enough controls wiring. You have a two stage a/c, you would need two wires for Y1, Y2. You also got a three stage air handler, modulating fan, with specific control settings you would lose, you need three wires for W1, W2, W3.
