Trying to replace thermostat for Geo Excel heat pump

Had 10 year old AprilAire thermostat that was not working properly. Bought Lux TX9600TS as replacement. Having issues with wiring diagram. Have photos of old wiring setup and new one.

You will need to place a jumper wire between Y and W with that Lux thermostat.

If you also have electric heat strips for emergency heat you will need a different stat. ( Geo units rarely have heat strips in my area).
