Johnson Controls W42AA-1 SPDT Humidity Control 10/90% RH

The Johnson Controls W42AA-1 SPDT Humidity Control is a product that is used to regulate humidity in your home or building, with little intervention from you. It uses a humidity sensor to obtain the humidity conditions existing in the surrounding environment. When the humidity level goes high over the set point, which varies between 10% and 90 %RH the control switches on your dehumidifier to bring down the humidity level. This automatically maintains it without forming mold which helps in preserving wooden furniture and improves qualities of life. This is a three-wire device with an SPDT switch, thus suitable for low voltage or line voltage humidity and dehumidification systems.
