C.A.P. Temperature/Humidity/CO2 AIR-3

The C.A.P. AIR-3 expands our line of atmospheric controllers by providing the ability to coordinate supplemental CO2 with your ventilation equipment. The AIR-3’s operation is similar to the AIR-1, with the addition of a photocell and CO2 outlets. The photocell 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.
