iGS-221

The iGS-221 integrated controller is the simplest and most complete solution for integrated climate management and CO2 enrichment or venting. Simultaneously controls 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!

  • Description

    Control module
    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.
    • Displays climatic conditions, CO2 concentration, advices, alarms and errors
    • Photocell to enable day/night set points

    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 a 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.
    • Three IGS-25 power boxes (6 auxiliary outputs)
    • Dry contacts for temperature and/or humidity alarms
    CO2 Control
    The iGS-221 controls CO2 enrichment equipment or the ventilation for 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 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.
    • Precise CO2 electronic sensor: ± 75 ppm
    • Adjustable set points for day and night from 0 à 4900 ppm
    Temperature and Relative Humidity Control
    The controller intelligently manages 4 actions: heating, cooling (AC or fan), humidifying, dehumidifying. It allows adjustment of 5 set points per climate parameter: set points for day, night, temperature and humidity's differential, alarm and event logging.
    • Temperature precise sensor: ±1.8°F (±1°C)
    • Adjustable separate set points for day and night
    • Relative humidity precise sensor: ±3.5% RH
    Temperature and Relative Humidity Control
    • Adjusting the hourly cyclic ventilation from 0 to 30 minutes.
    • Setting the ventilation (fan) to start in case of abnormally high relative humidity.
    • Setting the ventilation (fan) to start in case of abnormally high temperature.
    • Controlling temperature and humidity in a cold climate using the ventilation instead of an air conditioner and a dehumidifier.
    Capacity
    The iGS-221 feeds up to 45 amps of controlled equipment (need 3 separate circuits 110-120 V). Equipment which uses other voltage then 110-120 V, like large capacity air conditioning unit, may be controlled by using an iGS-DCS. You can also increase the capacity with a load switcher box iLS4-121, iLS4-121s or iLS4-241.
    • 120 V, 15 A, 2 HP load capacity (1 circuit)
    • 120 V, 45 A, 6 HP load capacity (3 circuits)
    • 120 V, 30 A, 4 HP load capacity (2 circuits)
