Found blower belt slightly loose. Tightened blower belt. New Daikin RTU: Tech found old, unused disconnect blocking access to compressor and service valve access panel. Tech moved disconnect out of the way. Found RTU low voltage wiring wired correctly for 2 stage heat pump, but vision pro tstat wired for conventional gas pack wiring. Also found Y and O in the same wire nut inside tstat wire junction box at RTU. Tech separated wiring inside junction box, corrected wiring at vision pro baseplate, corrected vision pro settings and tested system from thermostat in each mode.

Tech preformed CMA FULL SERVICE on 1 Gas Package Unit, 1 Split System, 1 Air Make-up Unit and 1 Exhaust Fan. Split System is operating within specifications at this time but Tech had to clean Evaporator Coil several times to get the excessive grease and debris removed. The inside of Air Handler Unit is also covered in grease. Tech did find Air Handler belt squealing upon start up, tech did adjust belt tension and line belt up but squealing persisted. Tech believes it is due to bearings in blower shaft. Compressor also tested in caution area of megohm test. Tech will have office contact customer with solutions. Gas Package Unit is operating within specifications at this time. Tech did find Air Makeup Unit with loose blower belt, tech has attached estimate to invoice for cost of replacing belt.

Tech found blower contactor pulled in and sending voltage, but blower not running. Tech could visibly see blower was burnt out. Shraeder caps also missing. Tech recommends replacing blower, filters and caps.
Tech found Unit 4 gets stuck on when power is put on Y. Y runs through the economizer and tech found no voltage on the blue wire going into the economizer board, but found 24v on the grey wire coming out of the board and going to pressure switch wires. This indicates that the board is getting stuck. Tech bypassed the board and wired blue to grey to get system operating properly temporarily. Board needs to be replaced
Tech was taking to the server room where the Tracer controls and tablet are located. Tech found the tablet with a connection lost screen and it was trying to reconnect. Tech rebooted the tablet and the Trane Tracer software loaded. Tech found that the system has a preset temperature of 72, each zone was reading between 70-72 depending on area. There is an option to adjust temperature setting up and down with limits. Tech adjusted all zones to 73 and the areas started warming up. There were alarms from 10/25 at 3:31pm, this could be when the tablet lost connection with controls and explain why it was not heating correctly. Recommend calling Dennis Kaufman (919-338-4648) with Brady Trane, his information was inside to controls cover, he can access it remotely and adjust set points according to season changes. System is working correctly.
Found thermistor to be faulty. Made a chart for future reference Replaced dats sensor with a defrost sensor off the truck stock System back to heating properly
