NOTES:1: For the Air handler without installing Electric Heat; connect the supply power to “L1”and “L2” .2: For the Air handler with Electric Heat, connect the supply power to circuit breaker. If you order the Heat Kit without circuit breaker, connect the power supply to the terminal block provided on the heater.3: Remove the red lead from “240V”terminal and then connect the red lead to “208V”terminal on the transformer for 208 volts. 4: Exchange the blower motor red wire and blue wire for low speed ;exchange the blower motor red wire and black wire for high speed default as medium speed of factory settings.5: TDR has a 1-20s on delay when “G”is energized and a 70-110s off delay when “G”is de-energized.6: “W2”wire is not provided in some models, and tap and seal the unused wire.
