Model X13 Communication Diagnostics
The X13 motor is communicated through 24 VAC low voltage
(Thermostat Control Circuit Wiring).
COMMUNICATION DIAGNOSTICS
1.
Start with unit wiring diagram to confirm proper
connections and voltage (see Figure 11).
The 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.)
