Upon my arrival I spoke with the customer about their concerns with the system not heating. Performing my diagnostics I found the control was not set up for heat pump but the customer believes he may have messed the settings up. After setting the comfort control for heat pump operation I tested the system finding the emergency heat and heat pump are performing to manufacture specifications at this time. I spoke with the customer about my findings and also went over that the system is not wired to dehumidifier but does have the capability. He did not wish to correct it today but will consider it in the near future. The customer stated they did not give it enough time possibly for the time delay to shut off. Went over our maintenance program and this is something he seems to be interested in but has a lot going on at the moment with tomorrow’s surgery. I will follow up after allowing time to heal and see if there are any more questions regarding this. Location has 2 heat pump systems.
