I arrived to inspected a system that was not heating properly. I found the system to be running in heat pump mode only. I checked the systems wiring and found the W1 terminal to not be wired in at the thermostat or at the air handler. I wired the system to operate to W1 on auxiliary heat. I cycled the system on and checked each heat strip to be running at 21/23 amps per heat strip. I left the system operating to the homeowners set up.
