Model X13 Communication Diagnostics
The X13 motor is communicated through 24 VAC low voltage
(Thermostat Control Circuit Wiring).
1. Start with unit wiring diagram to conrm proper
connections and voltage (see Figure 11).
2. Initiate a demand from the thermostat and check the
voltage between the common and the appropriate motor
terminal (1-5). (“G” input is typically on terminal #1, but refer
to wiring diagram!)
a. If the low voltage communication is not present, check
the demand from the thermostat. Also check the
output terminal and wire(s) from the terminal strip or
control relay(s) to the motor.
b. If the motor has proper high voltage as identied
above (Motor not Running #1), and proper low voltage
to a programmed terminal, and is not operating, the
motor is failed, and will require replacement.
