VVT Zone Controller

Wiring diagram for #33ZCT55CO2:

Wiring a Relative Humidity sensor

Part #OPNSENSRH-01

The Relative Humidity (RH) sensor is used for zone humidity control (dehumidification) if the rooftop unit has

a dehumidification device. If not, the sensor only monitors humidity.

NOTE

Do not use a relative humidity sensor and CO

sensor on the same zone controller.

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)
