The VAPOR-B1 is a humidity controller that can control either a dehumidifier or humidifier. Once the VAPOR-B1 is connected to a power source, and the humidification device is connected to the VAPOR-B1 power outlet, the device connected will be automatically controlled by the settings on the VAPOR-B1.

The user can choose to have different Day and Night humidity settings which will be automatically switched to the correct mode by the built-in photocell. The knobs make it easy to adjust the settings and provide a quick visual verification of the current set-points. The LEDs on the front of the unit will turn ON and OFF to show the user the current conditions of the VAPOR-B1.
