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.
