Wiring on old motor: Blue goes to BR/T9&O/T3 Yellow goes to R\T8&TanT2 Blk goes to pinkT7&bluT1 Tech replaced failed belt driven motor on RTU2. After repair, tech found no voltage in disconnect. Tech also found front RTU1 with no voltage in disconnect. Tech found breakers for both RTU 1 and 2 in the off position. Tech turned 125 amp breakers for both RTUs back on in the back electrical room. RTU2 is back heating correctly after replacing blower motor. Tech noticed no G call for electric heat strips on recently replaced customer supplied tstat. Tech corrected install setup menu. System is heating correctly with G and W1 call. System is 2 cool/1 heat conventional heat strip. Not a heat pump or gas pack. RTU1 blower motor turned on, but heat strips did not run due to a blown 60 amp line voltage fuse. Tech replaced fuse for testing purposes. Called Bruce who approved service call and fuse replacement by phone. All 3 RTUs are back running.
