Wiring the VVT Zone Controller for power
The VVT Zone Controller is powered by a Class 2 power source. Take appropriate isolation measures when
mounting it in a control panel where non-Class 2 circuits are present.
Carrier controllers can share a power supply as long as you:
• Maintain the same polarity
• Use the power supply only for Carrier Open controllers
