CO2 : iGS-100 CO2 Smart Controller

The iGS-100 CO2 controller is an essential control tool to efficiently and economically use CO2 enrichment for higher growth rates or to fulfill minimum ventilation needs day and night. The display shows the ambient CO2 concentration within ±75ppm at all times. The internal CO2 infra-red sensor reads values from 0 to 5000 ppm. The air sampling is optimized by means of an integrated fan. The control unit can be positioned up to 6 feet from the output box (a cable up to 50 feet can be used). The controller will automatically adjust its operating differential when the CO2 concentration overshoots or undershoots the desired setpoint. Two setpoints are used by the controller : day and night setpoints.

Interrupt other equipment during a CO2 enrichment or venting process :
The auxiliary output (#2) can activate or deactivate auxiliary equipment like exhaust fans while the CO2 output (#1) is active. An off delay timer of 5, 10, 15 or 20 minutes can be set to maintain activation or deactivation of output #2 after the CO2 enrichment or venting process has ended.

Check up on your CO2 set-up performance :
The controller is constantly analyzing its performance and issues in the form of hint codes a report to the user. The percentage ratio of the ON time of each output as well as the total differential for the CO2 control is obtainable through the hint codes. Therefore you can have a good idea concerning your grow room performance in your absence.

Be wary of your CO2 sensor precision :
After a full year of use the controller will display an error message which indicates to the user that a recalibration of the CO2 sensor is advised. Once the procedure is performed (10 minutes maximum) this message will disappear to reappear a year later. The controller also offer an altitude correction factor (up to 9500 feet).
