Upon arrival I found Check Valve Backflow Preventer on Water Feeder had failed. Replaced with new and verified no water feeding back into water heater. Bled all contaminated water out of water heaters. Took water sample of loop so we can make sure that wasn’t contaminated as well. Water Meter now reading 296.115 gallons after repair.

Warranty per Alex. Upon arrival customer showed me to units and flow center. Started by tracing all loop piping and checked for leaks, none found. Can see evidence of previous leaks but nothing indoors is currently leaking. Static loop pressure at about 23psi. Connected water meter from bottom of buffer tank to flow center (out). Water Meter before purging at 293.69 gallons. After purging and equalizing pressure at 293.85 gallons. Static water pressure at about 56psi. Showed customer water meter setup and explained how it works and how to read the meter. They may document how much water has been added, I left the box with the original value if they would like to do so.

I operated the unit on cooling mode #9 and set the flow rate to 9gpm by setting the pressure drop to 2.5psi. I cleaned the condensate pan and drain line and ran hot water to flush it out and to make sure it drained properly without leaks and that the condensate pump was working. I checked the electrical wiring and electrical systems, all are within specification. Filter is in good shape. I pressurized the ground loop to 65psi. I reset blower speeds from 5,5,10,11 to 3,3,10,11. I turned dehumidication on from the thermostat and explained all of this to the customer. Unit operating normal. I recommended adding a Blue Tube UV lamp but customer was not interested. I also recommended installing a whole house surge protector to the main panel box to protect the equipment. Customer asked for an estimate and would like to have this done next maintenance.

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.
