The Independant Temp & Humidity Control has the same features as the Temperature & Humidity Control 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 Independant Temp & Humidity Control, your desired temperature and humidity are automatically maintained. The Independant Temp & Humidity Control is rated for 15 amps @ 120 volts.
