Green Air CDMC-6 CO2 Sequencer and Sensor
The CDMC-6 pairs a CDM-6000 infrared sensor with a CDDS-2 sequencer that reads the air once a second. It measures CO2 across 0-5000 ppm and controls it from 300-5000 ppm. An adaptive Overshoot Protection Logic learns the room so levels settle without the swings a plain set-point controller leaves. A built-in photosensor defeats enrichment during the dark period.
Setting Up the CDMC-6 in Enrichment or Venting Mode
A mode button switches the system between CO2 enrichment and venting stale air. Mount the sensor mid-room, away from the CO2 gear and clear of foliar spray. Give it a 24-hour adjustment period with doors closed each time you move it. Set your ppm, hysteresis, and elevation, and it holds the level on its own. It runs on 120V at 12A switching capacity.
Key Features
- 0-5000 ppm range: Infrared sensor measures CO2 from 0-5000 ppm, controls 300-5000 ppm.
- Overshoot Protection Logic: Adaptive algorithm learns the room to hold ppm without big swings.
- Night photosensor: Defeats CO2 enrichment automatically during the dark period.
- Enrichment or venting: Mode button switches between adding CO2 and exhausting it.
- 120V, 12A switching: Runs standard 120V equipment; 220-240V available by special order.
- Made in USA: Manufactured and factory-calibrated in Oregon.
