The CAP AIR-2 has the same features as the AIR-1 with the exception of separate temperature and humidity outlets. This allows you to control the temperature and humidity independently. Once you have connected your temperature control device (air conditioner, fan, etc) and a dehumidifier to the AIR-2, your desired temperature and humidity are automatically maintained. The AIR-2 is rated for 15 amps @ 120 volts.
