Overview

The Carrier 33ZCT56CO2-02 is a non-communicating wall-mounted sensor that combines CO₂ and space temperature sensing in one unit to support effective ventilation and indoor comfort control.

Features

By measuring both carbon dioxide levels and space temperature, this sensor provides the data needed to support proper ventilation and comfort control. Reliable readings help building systems respond to occupancy and maintain healthier indoor environments.

Automatic background calibration helps maintain accuracy over time without manual recalibration. This reduces maintenance effort while supporting consistent system performance throughout the life of the sensor.

A low-profile design with an integrated mounting plate and terminal blocks streamlines installation. Multiple output options and onboard setpoint adjustment make it easy to integrate into existing Carrier control strategies.
