    Lux TX1500E Wiring Help

    I have bought a Lux TX1500E thermostat and can't figure out the wiring.
    Here is my existing RUUD Thermostat and the Lux. Can anyone help me match them up?

    Your new thermostat will not work with your system. You need a thermostat capable of a heat pump system WITH aux heat.
