Controller. The default baud rate is 76.8 kbps.
NOTE Use the same baud rate for all controllers on the network segment.
Insert the power screw terminal connector into the VVT Zone Controller's power terminals.

Wiring sensors to inputs

You can wire the following sensors to the VVT Zone Controller's inputs:
•
Space temperature sensor (page 12)
•
Alternate space temperature sensor (page 14)
•
Supply Air Temperature sensor (page 15)
•
Duct Air Temperature sensor (page 16)
•
CO sensor
2
•
Relative Humidity sensor (page 19)
• Remote occupancy contact sensor (page 20)
NOTE This document gives instructions for wiring the sensors to the VVT Zone Controller. For mounting and
wiring the sensors, see the Carrier Sensors Installation Guide.
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.
• Do not run sensor or relay wires in the same conduit or raceway with Class 1 AC or DC service wiring.
• Do not abrade, cut, or nick the outer jacket of the cable.
• Do not pull or draw cable with a force that may harm the physical or electrical properties.
• Avoid splices in any control wiring.
