Start with unit wiring diagram to confirm proper
connections and voltage (see Figure 11).
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 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 always refer to wiring
diagram.)
