    Make sure you have fresh batterys.
    Make sure you follow and adjust all items in the INSTALLER/CONFIGURATION MENU.

    Use RH Power for Heating
    Use W/E Heat Relay/Emergency Heat Relay (Stage 1)

    Here is a copy of your directions

    Wiring diagrams

    NOTE you can leave the factory jumper in between RH and RC if so equipped.

    You have a very fancy thermostat for such a simple job. I hope it works out for you.

    Got a good deal on it. I used the black on RH and the white on the W/E. Set it as a Single stage. Still not working. Sorry to bother

    If you set the controls up exactly as mentioned in the thermostat program it should work.

    With this thermostat no C or common is necessary so it should be working. Does the screen light up?
    Are the battery installed correctly?
    Are the batterys know to be good not just guessing that they are good?

    The thermostat depends upon batterys for proper operation since there is NO C wire.

    Are you sure you have power going to the system? If you remove the thermostat and jumper the two wires will the heat run? If your heat runs your thermostat is set up wrong or its bad. If it doesn't work after you jump the wires you may have a high or low voltage problem.
