Upon arrival, thernostat is in off mode. Turned on to heat to test heat pump operation. Heat pump comes on and is operating with a 20F temperature rise. Turned system on to emergency heat and it was operating with a 10F temperature rise which is below spec. Upon further investigation, found that the breaker inside of breaker panel for second high voltage supply to air handler was off. After talking with Jamie, he said that the breaker on the airhandler was off aswell but did not know that there was a second breaker for furnace in breaker panel. After turning on breaker, emergency heat temperature rise is 25F and within spec. System was only operating with one of the three heat strips. All three heat strips are operational at ~20A draw, and 240V. System is properly operating at this time.
