Customer complaint that on both thermostats the back light would not come on and would not turn off the unit. I checked inputs from each thermostat at the zone board and they are normal. The back lights were lighting up now. It’s difficult because the unit was operating normal from the zone stats and the zone board. Without being able to see the problem I cannot condemn the thermostat or zone board. I checked temperature rise on the unit and heat of extraction and it’s within specification. Maybe it was an anomaly. I put an estimate in the system for replacing one or both thermostats.

Upon arrival I spoke with Bryan from Magnolia/Best Buy as he was the salesman for this automation system. He gave me thermostats and informed me that customer was unavailable because he was working and had conference calls. Contact then showed me to all thermostats. Started by replacing all Honeywell 8000 thermostats with smart Savant thermostats. Shut down power to all units. Removed old thermostats. Cleaned wire connections. Installed new thermostats. Returned power to systems. Thermstats now reading “Please Configure this Device”. Cannot confirm operation because Magnolia/Best Buy is not finished and they are programming thermostats. We did not supply these thermostats so we are not liable for warranty purposes. Also could not collect from customer because he was unavailable.

I replaced all filters that were provided by the customer. I confirmed/ adjusted the flow rates and pressurized the ground loop to 65 psi. I checked the electrical wiring and electrical systems, all are within specification. I slowed blower speed for the attic air handler to increase temperature rise. I made sure auxiliary heat strips were operable. Both units are operating normal. In regards to the humidifier service, I replaced the water solenoid valve so that it would distribute water during a call for humidity. The original solenoid was inoperable, despite receiving voltage. Humidifier is working properly without leaks.

I tested auxiliary heat. I installed two jumper wires on the auxiliary heat board so that the timing of the elements is correct. The unit had recorder 999 out of envelope faults. The blower speeds were incorrect. I changed them from 4,6,10,11 to 2,3,10,11. I then operated the unit on compressor speed #12 heat mode. Refrigerant pressures were normal. I slowed flow rate by 15%. Heat of extraction matches printed data. I checked the electrical wiring and electrical systems. I enabled dehumidication on the thermostat. I pressurized the ground loop to 65psi. Unit operating normal. Customer may want to consider adding a humidifier to the system. I will send an estimate.
