Output wiring
To size output wiring, consider the following:
• Total loop distance from the power supply to the controller, and then to the controlled
device
NOTE Include the total distance of actual wire. For 2-conductor wires, this is twice the
cable length.
• Acceptable voltage drop in the wire from the controller to the controlled device
• Resistance (Ohms) of the chosen wire gauge
• Maximum current (Amps) the controlled device requires to operate
1 Verify that the Room Controller's power and communications connections work
properly.
2 Remove power from the Room Controller.
3 Connect the input wiring to the screw terminals on the Room Controller.
