    Here is a wiring diagram for your old thermostat

    I need the complete exact model number for your new thermostat.

    1F72 needs more numbers after it.

    I cannot supply the proper info without the exact model number for the White Rodgers.

    Sorry for not supplying all needed info. 1F72 151 is the correct model number. It's a heat pump 5/2 day programmable model 20 to 30 v max 50/60Hz 1.5 amp max. I don't know if this will be enough info butim hoping it will be. I'm at a total loss when it comes to hvac. Thanks a lot for your time and know how!
