Thank you for purchasing the TrolMaster's BETA-6 Day/Night Humidity Controller.

The BETA-6 offers indoor gardeners an economical and simple method of monitoring and controlling humidity level within the grow area. It utilizes a highly visible and intuitive LED screen to let you know current humidity level or max/min humidity recorded values.

Choose your desired humidity setpoint for day and night mode. When the humidity is lower than the setpoint, the controller will automatically turn on the power supply of the humidifier for humidifying purpose and the its LED indicator stays on. When the humidity is higher than the setpoint, the controller will automatically turn on the power supply of dehumidifier for dehumidifying purpose and the corrresponding LED indicator stays on.

It can also record the max and min humidity records during use.

A built-in photocell located on the sensor automatically detects the day and night status, controlling the humidity in day/night mode separately. A remote humidity sensor with 16 feet long cable allows close placement to the plant canopy.
