iGS-221 Multi Controller 

 
Integrated controller for temperature, humidity and CO2

 

Intelligently manages 6 actions: CO2 enrichment, venting, humidifying, dehumidifying, heating and cooling.

Prioritizes actions according to a logical sequence; allowing the plants to keep their stomas opened for an optimal CO2 absorption!

Feeds up to 45 amps of controlled equipments (110-120V; 3 separate circuits needed).

Provides automatic differential for precise CO2 concentration control.

Ready to use, just adjust your set points!

Offers a 24 hours log to know your garden's conditions.

Hassle free 3 years warranty.

7 days free technical support.

ONLY ONE controller to manage ALL indoor garden's climate parameters!

 

The new software 1.29:

 

1. Allows to adjust the hourly cyclic ventilation from 0 to 30 minutes;

 

2. Allows to set the ventilation (fan) to start in case of abnormally high temperature

 

3. Allows to set the ventilation (fan) to start in case of abnormally high relative humidity.

 

4. Now allows to control temperature and humidity in a cold climate using the ventilation instead of an air conditioner and a dehumidifier.

 

Improvements 2 and 3 should provide for emergency in case the AC unit or the dehumidifier is temporarily out of order. That way the "Fan" outlet on the iGS-221 will be usable for manual emergency activation, for adjustable cyclic ventilation if needed, for emergency cooling or dehumidifying.

Useful Tips:

For an accurate CO2 sensor calibration at all time, use a 1000 ppm certified calibration gas.

 

iGS-221 operates the intake-exhaust fan(s) for only 2 minutes per hour to replenish the garden's atmosphere in oxygen as it is needed for the plants and for a safe CO2 combustion generator operation. iGS-221 does not use fan(s) to cool or dehhumidify the grow room.

 

When a CO2 combustion generator (propane or natural gas) is used to raise the CO2 level, ventilation for at least 2 to 5 minutes is mandatory to replenish the oxygen supply required by the generator's combustion. Insufficient oxygen supply in the garden's atmosphere provokes production of carbon monoxyde, toxic to humans, and ethylen, toxic to plants: often seen as poisoned plants leaves roll into itself.
