The iGS-221 can operate the intake and exhaust fans cyclically to replenish the garden's atmosphere in oxygen as it is needed for the plants and for safe CO2 combustion generator operation.

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 allows the accumulation of carbon monoxide, which is toxic to humans, and ethylene, which is toxic to plants.

    This combination does not exist.

    iGS-221 CO2/RH/Temp Smart Controller

    One Controller to rule them all! The iGS-221 is one easy-to-use controller that will control and manage all of your climate parameters! Control up to 6 different pieces of equipment!

    The iGS-221 integrated controller is the simplest and most complete solution for integrated climate management and CO2 enrichment or venting. Simultaneously control the temperature, humidity, and CO2 concentration. The iGS-221 prioritizes actions according to a logical sequence, avoiding contradictory actions. Intelligently manages simultaneously 6 actions: CO2 enrichment, venting, humidifying, dehumidifying, heating, and cooling. Ready to use, just adjust your set points!

    Multiple operation modes are available to ensure effective control. The controller will automatically adjust its operating differential to keep conditions closest to temperature, relative humidity, and CO2 concentration set points. The controller database allows you to know the real conditions of your garden over the last 24 hours.

    Connection Module: Connected to a compatible alarm system (0.6 A @ 120 Vac or 2A @ 30 Vdc), the connection module will activate alarms to notify a temperature or humidity control problem. The three IGS-25 power boxes, each controlling your equipment with 2 auxiliary outputs, can be connected (Ethernet or RG45 cable) on different circuits up to 50 feet off the connection module.

    CO2 Control: The iGS-221 controls CO2 enrichment equipment or the ventilation for the intake of fresh air containing CO2. It can operate the intake-exhaust fan(s) cyclically to replenish the garden’s atmosphere in oxygen as needed for the plants and for the CO2 combustion generator. The air sampling is optimized by means of an integrated fan and the internal CO2 sensor reads values from 0 to 5000 ppm.

    Temp and RH Control: The controller intelligently manages 4 actions: heating, cooling (AC or fan), humidifying, and dehumidifying. It allows adjustment of 5 set points per climate parameter: set points for the day, night, temperature and humidity differential, alarm, and event logging.

    iGS-211 Features:

    • 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 stoma open for optimal CO2 absorption
    • Feeds up to 45 amps of controlled equipment (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-hour log to know your garden’s conditions
