Digital C02 Sequencer

Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, mineral wool, or coconut husk

The CDDS-2 activates or deactivates your CO2 enrichment or CO2 venting (exhaust) equipment as necessary to maintain CO2 PPM based on your set point. For best results, turn off all exhaust functions and close all doors and windows during the initial 24-hour adjustment period. You must allow this 24-hour adjustment period every time you relocate the system to a new space. After 24 hours, you can restart your exhaust functions and continue as normal.
In enrichment mode, the CDDS-2 employs a sophisticated adaptive algorithm "Overshoot Protection Logic" which learns the dynamics of the space being controlled. This allows the system to avoid dramatic overshoots inherent to set point controllers or timed C02 enrichment. These learned parameters are stored in memory, even when the "POWER" is off, until you reset the CDDS-1.


FEATURES



  • Built-in Photo Sensor for enhanced control

  • Easy to program and operate with adjustable hysteresis (differential)

  • Durable infrared sensor

  • CO2 measurement range from 0-5000 PPM

  • CO2 control range from 300-5000 PPM

  • Easy to read LED display light will not affect plant growth

  • Mode indicator LEDs

  • Factory calibrated and inspected for precision performance

  • Operates on 120 VAC at 60 Hz, 12 Amp switching capacity

  • Manufactured in Oregon, USA
