CO2 Controller (CDDS-2)

The Green Air Products CO2 Digital Sequencer (CDDS-2) transforms the CO2 monitor into a powerful and versatile controller. Provides a easy to use set point controller which enables the user to adjust carbon dioxide level and span. CO2 values are adjustable in 10 ppm increments from 0 to 5000 ppm. The span between CO2 “On” and CO2 “Off” (hysteresis) is also adjustable in 10 ppm steps up to 300 ppm differential. The LED changes color to indicate carbon dioxide function status. The CDDS-2 also provides a switchable photo sensor to disable carbon dioxide production during darkness periods.

Enrichment or Venting:
The CDDS-2 controller has a standard 110 VAC outlet to operate CO2 producing or venting equipment. The MODE button switches between carbon dioxide enrichment or CO2 venting functions. Enrichment is the normal mode for CO2 enrichment operations. Venting mode is for purposes of removing excessive levels of carbon dioxide. This is used for excess CO2 accumulation in hospitals, class rooms, factories, conference rooms, offices, laboratories and mushroom culture facilities.

Overshoot Protection Logic:
The CDDS-2 Carbon Dioxide Digital Sequencer features Overshoot Protection Logic programming which will automatically maintain the proper dosing parameters necessary to keep any size area enriched within a set tolerance regardless of the particular characteristics of the enclosure. If on the initial cycle, the controller senses that excess CO2 has been administered, it will automatically compensate for the next dosage. This will assure that the proper levels are constant and maintained at all times with complete accuracy and save money at the same time.
