Wiring a Duct Air Temperature sensor to an input

Part #33ZCSENDAT
The VVT Bypass Controller must be connected to a Duct Air Temperature (DAT) sensor that monitors the
temperature of the air delivered by the air source.
NOTE This document gives instructions for wiring the sensor to the VVT Bypass Controller. For mounting and
wiring the sensor, see the Carrier Sensors Installation Guide.

Wiring specifications

Cable from sensor to controller:
Maximum length:

To wire and mount the DAT sensor

Wire the sensor to the controller. See diagram below.

NOTE Sensor wiring does not have polarity. The wires can be connected to either terminal.
Using electrical tape, insulate any exposed wire to prevent shorting.

Wiring field-supplied actuators to the analog output

You can wire a high-torque actuator or parallel actuators to the controller's 0–10 Vdc analog output.
NOTE You cannot use the VVT Bypass Controller's built-in actuator if wiring external actuator(s) to the analog
output.
