Start with unit wiring diagram to confirm properconnections and voltage (see Figure 11).2. Initiate a demand from the thermostat and check thevoltage between the common and the appropriate motorterminal (1-5). ("G" input is typically on terminal #1, butrefer to wiring diagram!)a. If the low voltage communication is not present, checkthe demand from the thermostat. Also check theoutput terminal and wire(s) from the terminal strip orcontrol relay(s) to the motor.b. If the motor has proper high voltage as identifiedabove (Motor not Running #1), and proper low voltageto a programmed terminal, and is not operating, themotor is failed, and will require replacement.24VAC "R" Signal throughthermostat output.24VAC Common24VAC Common24VAC "R" Signal throughthermostat output.Model SelecTech Communication DiagnosticsThe SelecTech motor is communicated through 24 VAClow voltage (thermostat control circuit wiring).1. Start with unit wiring diagram to confirm properconnections and voltage (see Figure 12).2. Initiate a demand from the thermostat andcheck the voltage between the common and theappropriate motor terminal (1-5). (“G” input istypically on terminal #1, but always refer to wiringdiagram.)A. If the low voltage communication is notpresent, check the demand from thethermostat. Also check the output terminaland wire(s) from the terminal strip or controlrelay(s) to the motor.B. If the motor has proper high voltage asidentified above (If the Motor Is Not Running#1 on page 27), proper low voltage to aprogrammed terminal and is not operating, themotor has failed and will require replacement.Speed Tap 1: Vent SpeedSpeed Tap 2: Balanced Climate SpeedSpeed Tap 3: Default SpeedSpeed Tap 4: Medium SpeedSpeed Tap 5: High Speed
