Honeywell - C7232A1008

CONTROLLER: C7232A1008 CARBON DIOXIDE (CO2) SENSORS BY HONEYWELL ARE STAND-ALONE CARBON DIOXIDE (CO2) SENSORS FOR USE IN DETERMINING VENTILATION NECESSITY WITH HVAC CONTROLLERS. SENSOR MEASURES CO2 CONCENTRATION IN VENTILATED SPACE OR DUCT. SENSORS ARE USED IN VENTILATION AND AIR CONDITIONING SYSTEMS TO CONTROL AMOUNT OF FRESH OUTDOOR AIR SUPPLIED TO MAINTAIN ACCEPTABLE LEVELS OF CO2 IN SPACE. 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. SPST RELAY OUTPUT. 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.
