Chris did a great job!
Brittle - Mount Airy, MD
I really appreciated that chris called ahead, was on time, and found a problem other technicians overlooked.
I replaced the air filter with one provided by the customer. I found the pressure drop and heat of extraction to be lower than printed data for this unit. The axb setup was at 50 and 100 vs pump which allows for maximum flow through the pump. There was no valve on the loop piping so I went to the pumps and the vs pump was warm and working but the other pump was cold and clearly not working. I found no voltage at the pump and traced it to inside the unit. I wired it into the fixed pump relay p1 and p2 and started the unit. Pump drawing .98 amps and the pressure drop actually needed to be slowed down slightly with both pumps working. I set flow rate correctly. Loop pressure was good. I checked the electrical wiring and electrical systems, all are within specification. Unit operating normal.
Called customer and he informed me that nobody would be home during service. During diagnostics I found no LED lights at boiler or zone panel. Checked voltage and found none at boiler. Got access to basement of house per customer and I found 20amp breaker tripped. Reset and tested unit operation. Also labeled breaker. Found 10amps total ONLY when boiler is firing up. During normal operation I found unit was pulling 6.5amps total. Checked operation of pumps, boiler, stat, and zone control. Amp draw readings taken were from main power at breaker reading all motor amperages. Found P/T sight glass on boiler is full with water and difficult to read. Continued to run system and found no additional problems. Suggest 20amp breaker get replaced, possibly weak and prematurely tripping. Left system running to make sure Desert Aire System satisfies and customer sees that it is working. Locked basement door and front pool door. Left back pool door unlocked. Office please follow up with customer. N
