The Model A76 Digital Dehumidifier Control communicates with your dehumidifier, allowing you to control the operation of the unit from a distance. Using an onboard sensor, the Model A76 Dehumidifier Control monitors the relative humidity in the space in which it is located and displays the measured relative humidity on the digital display. This is a wired control unit that must be hardwired to your dehumidifier. The Model A76 digital control can also be used as a communicating remote control for your dehumidifier, allowing you to set the relative humidity level for your grow room and control your Anden dehumidifier from a convenient living space location. This makes it easy for you to control your Anden dehumidifier if it is located in an inconvenient or hard to access area.
