I am a highly skilled home service professional. I recently completed a job where the customer's zone system was not communicating correctly with the unit. I diagnosed the issue and found that the tsat was wired incorrectly and not set to heat pump. I configured the tsat and system is cooling and running correctly. I also inspected the attic to make sure the dampers were closing and opening correctly, and they were. The customer paid $79 for the diag fee with a card.
