The Day & Night Dehumidifier Controller version is for use with your existing dehumidifier. Use the dials to set specific humidity for day and night.
By Plugging a dehumidifier into the Day & Night Dehumidifier controller you are able to regulate a dehumidifier by switching it on and off. Once you have set your desired day time and night time highest accepted levels of humidity the controller switches your dehumidifier on and off. Remember this controller can only regulate a dehumidifier and so the reduction of humidity within your grow room. To control the addition of humidity use Global Air Supplies Day Night Humidifier controller. Not for use with Quest dehumidifiers.
