I arrived at the customer's home to find that the system was off and the Tstat control was not working. I checked the batteries and reset the system, and it came right on. I checked the pressures and everything looked ok. The system needs a really good tune up, but the pressures are a tad bit low. I hosed off the filter and let it dry. Per Wayne's instructions, I set the tsat to fan ON. The customer paid $79 with a card.
