Electric furnace/heat pump

[Joshua L. Frederick]

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.

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...
