Honeywell C7232 Carbon Dioxide (CO2) Sensor

The Carbon Dioxide (CO2) Sensors and Controllers are stand-alone carbon dioxide (CO2) sensors for use in determining
ventilation necessity with HVAC controllers. The sensor measures the CO2 concentration in the ventilated space. (These
models are wall-mount only.) The sensors are used in ventilation and air conditioning systems to control the amount of
fresh outdoor air supplied to maintain acceptable levels of CO2 in the space.
Features:
• Models available with LCD that provides sensor readings and status information.
• Non-Dispersion-Infrared (NDIR) technology used to measure carbon dioxide gas.
• Gold-plated sensor provides long-term calibration stability.
• C7232 provides voltage or current output based on CO2 levels.
• Models available with SPST relay output.
• Proportional plus Integral (P+I) control algorithm.
• Used for CO2 based ventilation control (Demand Control Ventilation (DCV)).
• Automatic Background Calibration (ABC) algorithm based on long-term evaluation reduces required typical zero-drift
check maintenance.
• Digital input with programmable delay time for occupancy function using a sensor, pushbutton, or switch.
