This controller functions as a day/night humidistat with separate humidity setting for each. Set your day and night maximum desired humidity seperately
and the photosensor will activate humidistat depending on photoperiod. The HH-HH-1P outlets operate Humidifying/Dehumidifying equipment. They
will come ON at the same time.
Remember that this controller will only handle 15 amps or less. For high load humidifiers/dehumidifiers see our HAR-1 high amperage relays to switch the
load for the controller.
