Electric furnace/heat pump

Electric furnace with a heat pump. Emergency/auxilliary heat was the only way furnace operated. Now my question, can a system be hooked up to only operate in aux/emergency only, instead of using the heat pump?

Thanks for any helpful insight.

Yes.

Disconnect the yellow wire from the thermostat.

Where you in Nashville? I had one like that last week! :wink:

There are many reasons it may be off, like tripped off on high pressure switch from operating in heat when it’s hot out…

Smyrna Tn last week: seized outdoor fan motor (off on high head pressure)…

Tripped breaker, blown fuse on outdoor unit, inside will still run in em heat…
