Disconnect electrical power to the VVT Zone Controller before wiring it. Failure to follow this warning could
cause electrical shock, personal injury, or damage to the controller.
Wiring specifications
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
