I repair A/c and heating as well as many other Items, Mostly commercial refrigeration. I completed my refrigeration and heating school in the early 90s. Kept all my grades in the upper 90%. Since I live in a small desert community I have to do a large variety of things to stay busy. The point is that I don't get daily or even monthly experiance on HeatPumps, A/C etc.
Now I am installing a White rogers 1F83-277 Thermostat for a customer. I am installing it to operate a GMV95/GCV9 two-stage PROPANE furnace and a GSH140421ad HeatPump from Goodman.
I can hook it up to use the heatpump as an A/C very easily. But I am trying to hook the heat pump up so that it runs on the thermostat as the primary heat and the Furnace comes in as a back up. I need to get a fossil fuel kit to do this. But for the two weeks or more I am waiting for the parts The customer would like heat. I could just hook up the funace and wait but It seems to me there is a way to wire this so that the Heat pump works on the thermostat as it normaly would and if I select emergency heat the furnace will take over.
Does anybody have any ideas for me or a better answer than I am trying to do? I mainly just want to learn how to do this even though it is not important for this application.
