I have a Honeywell 1 Heat/1Cool thermostat (TH6110D1013) that I would like to use with a Rheem 2 stage gas heat furnace. I think it is possible but would I get the same benefits as having a thermostat with 2 heat/1 cool?

Would I just connect the W terminal on the Thermostat to the W2 on the Rheem furnace? Thanks

Sometimes your furnase will automatically go into high fire after a timed pre fire on low.

If this is the case try running w1 and leave w2 alone on the furnase, set temp very hige and use a stopwatch, a users manual might be helpful if you need a long run the high fire kicks in after oh lets say 10 min and will stay in high fire till the thermostat is satisfied.


It's the holiday and I've been into the cooking sherrie please be safe
