Greetings,

We currently had a Honeywell Digital TH5220D1003 (non programmable) thermostat (link here: Product) on our downstairs Westinghouse (Nordyne) FT5BD-030K HVAC (link here: WESTINGHOUSE FT5BD-030K Heat Pumps). There is a separate unit for the upstairs. It was working fine. Then we wanted to install a new honeywell digital thermostat (model RTHL2310) that was programmable (link to product here: RTHL2310B | 5-2-Day Programmable Thermostat).

I removed the wires and labeled them. They are either:

Conventional (which I assumed to the correct one)
R (red wire), Y (yellow wire), C (blue wire), W (red wire), G (green wire), W2 (white wire)

OR

Heat Pump
R (red wire), Y (yellow wire), C (blue wire), O/B (red wire), G (green wire), Aux (white wire)

Next I connected the new thermostat as follows matching the conventional labels above:
R (red wire), W (red wire), Y (yellow wire), G (green wire). I did nothing with C (blue wire) or W2 (white wire).

The result was that the unit just blew warm air. I then hooked the old thermostat back up and still no cooling.

So I believe the Westinghouse is not working period and I do not have the wiring correct.

Any direction would be greatly appreciated!

Thank you,
DuBose Griffin
