AIR4 Atmosphere Controller

The AIR-4 allows you to control the temperature and humidity independently within your growing environment. Connect your ventilation equipment (air conditioner, fan, etc.) to the exhaust outlet. Then set your temperature and humidity to the level that you wish to maintain. The AIR-4 provids the ability to coordinate supplemental CO2 with your ventilation equipment. The AIR-4's operation is similar to the AIR-2, with the addition of a photo cell and CO2 outlets. The photo cell ensures that your CO2 device (CO2 valve or generator) only activates when your lights are on. To conserve CO2, the CO2 outlets are automatically disabled while your ventilation equipment is running. The Air4 also has an additional outlet that is powered only while the lights are on. The AIR-4 is rated for 15 amps @ 120 volts.
