Autopilot Dehumidifying Humidistat
Available only from Hydrofarm , the Autopilot Dehumidifying Humidistat is a compact and easy-to-use controller for dehumidifiers and exhaust fans . The grower simply plugs it in , plugs the dehumidifier into its outlet , then sets the preferred relative humidity ( RH ). When its built-in sensor detects that the RH has exceeded the setpoint by at least one per cent , it automatically activates the dehumidifying device , and conversely , when the RH in the room drops by at least one per cent , the Humidistat will cut power to the dehumidifier or fan . The Autopilot Dehumidifying Humidistat also features a green LED light that stays illuminated while the dehumidifier is powered , as well as a digital screen display . It is ETL-listed and carries a three-year warranty .
