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 confirm 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 identified
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.

Model SelecTech Communication Diagnostics
The SelecTech motor is communicated through 24 VAC
low voltage (thermostat control circuit wiring).
1.
Start with unit wiring diagram to confirm proper
connections and voltage (see Figure 12).
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 always 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 (verified
in Step 1 of
If the Motor Is Not Running
on
page 21), proper low voltage to a programmed
terminal and is not operating, the motor is
failed and will require replacement.
