The iGS-110 is the ideal controller to manage both temperature and humidity at the same time. With day/night detection and its different operating modes, you will manage your climate in any way you wish. The iGS-110 is a smart device that provides you with information on the performance of your equipment allowing you to optimize your configuration.

Control Module

The controller has two separate auxiliary outputs for equipment correcting the temperature and relative humidity. The output controlling the temperature allows cooling, heating, or cooling and dehumidifying. The output for relative humidity helps to humidify or dehumidify. The controller will automatically adjust its operating differential to keep conditions closest to temperature or relative humidity set points.

  • Temperature precise sensor: ±1.8°F (±1°C)
  • Adjustable separate set points for day and night
  • Relative humidity precise sensor: ±3.5% RH
  • Adjustable operation priority and shutoff additional delay

Strategies To Garden Without CO2 Enrichment

The two auxiliary outputs can be configured independently according to the temperature or humidity control mode For example, with cooler and dryer air outside, the fresh air intake and CO2, cooling and dehumidification can be provided by ventilation controlled by the 1st output, while the 2th output can control heating or humidification.

  • 1 outlet controlling CO2 equipment
  • 1 auxiliary outlet for climate control

Control Temperature Or Humidity With Highest Priority And CO2 Enrichment

Plug a power strip in an auxiliary outlet of the temperature and humidity controller (iGS-110) and plug the temperature or humidity prioritized equipment and the iLS120-OFF sense cord. Feed the iLS120-OFF in different circuit and plug in a CO2 controller (iGS-061 or iGS-100) to manage CO2 enrichment equipment.

  • 1 auxiliary outlet for temperature control
  • 1 auxiliary outlet for RH control


To increase your cooling/heating and humidifying/dehumidifying capacity, plug an iLS120-ON to auxiliary outlets to control additional equipment on different circuit (adds 15 A, 120 V), or a load switcher box iLS4-121, iLS4-121s or iLS4-241 to control up to 8000 W of equipment (4 outlets up to 15 A, 120 V or 240 V). It can also control large capacity air conditioning unit through an iGS-DCS relay (other voltage then 110-120 V).

  • One IGS-25 power boxes (2 outputs)
  • 120 V, 15 A, 2 HP load capacity
