Spring Pm On 04/19/19 On arrival set unit to call for cooling measured supply and return air temp measured voltage and amps inspected electrical connections checked drain and cleaned checked filter cleaned checked condenser coil is cleaned checked compressor capacitor also all other electrical connections unit tested unit operating normal at this time.

Installed 75 gallon hot water heater . ( removed old water heater and set new one . Installed new expansion tank while connecting water lines . Reconnected gas and checked for leaks . Lit pilot and checked operations)
Completed AC inspection on unit #2 which serves back area . Front lobby unit I changed filters and I confirmed that compressor is grounded and recommended replacement .
I installed the duct mounted pressure blow off damper and took multiple pictures of it and uploaded them to this file. I reset blower speeds to factory settings 3,6,8,10. I tested the operation of the damper. It pretty much opens when only one zone is calling but closes when both zones are calling. There had been several more high pressure faults, which I cleared. With this repair the unit does not overheat as it was doing previously.
Smaller zone duct size 8*12. Supply plenum 6*18. I completed a tasking sheet for the equipment in heating mode. When only one zone is calling for 2nd stage heating the unit can fault on high head pressure. I spoke with Denny about this and a blow out air damper will solve this problem. I took pictures and measurements of the supply duct and the smaller zone duct as well. The zone board has to log 10 minutes of rn time to engage 2nd stage operation. I set the flow rate correctly and confirmed heat of extraction above printed data. There were no high amperage draws on any device. Customer advised to give electric bill another cycle for accurate comparison. Other than the high head pressure issue which only happens occasionally the unit is operating normal.
