Programmable CO2 Controller with S01 Sensor ICC-500T

● Plug and play, simple operation.● Dual relays, are able to connect with the CO₂regulator or generator and the exhaust fan simultaneously.● Dual readouts, displays the current measured CO₂ concentration and the set CO₂ concentration simultaneously.● CO₂ calibration.● Programmable high/low CO₂ concentration alarm.● Widely applied in ventilation system, building control and HVAC equipment. The difference between the S01 and B01 sensor version Plug the CO₂ Controller and the sensor When the CO₂ sensor is inserted, the controller will take about 8 seconds to identify. Then the PV window will display 8888 and blink, the SV window will display the CO₂ concentration setting. Waiting for about 120 seconds After 120 seconds, CO₂ module works stably, and the PV window stops blinking and displays the measured CO₂ concentration. Within 120 seconds, the buttons cannot be operated , the indicators of WORK1 and WORK2 are off, and the WORK1 and WORK2 have no output. Plug your devices int
