Wiring a Duct Air Temperature sensor
Part #33ZCSENDAT
The Duct Air Temperature Sensor (DAT) monitors the supply air temperature and is required for cooling and
heating air source applications on non-Carrier dampers and for stand-alone operation without ducted reheat.
Wiring specifications
Cable from sensor to controller:
If <100 ft (30.5 meters) 22 AWG, unshielded
If >100 ft (30.5 meters) 22 AWG, shielded
Maximum length:
500 feet (152 meters)
To wire the DAT sensor to the controller
1
Wire the sensor to the controller. See diagram below.
NOTE
Sensor wiring does not have polarity. The wires can be connected to either terminal.
2
Using electrical tape, insulate any exposed wire to prevent shorting.
3
