I just moved to a new home which uses a heat pump with emergency heat. The old thermostat has an E wire and an AUX wire. I am not sure were they would go on my thermostat. The manual references emergency heat several times but does not say anything about the wiring of it.
Old is on the left. New on the right.
I tried contacting support and they told me to call an electrician. Any help is much appreciated.
