  • HH-HH-1P Day / Night Humidistat


    Qty :


    Model HH-HH-1P

    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.
