The TrolMaster BETA-6 is a dedicated single-zone 120V digital humidity controller for humidifiers and dehumidifiers. It provides independent day and night relative-humidity setpoints and automatically switches between them using the built-in photocell in the included SA-H1 humidity/light sensor, eliminating the need for separate timer wiring. The controller uses a 5% humidity deadband to reduce rapid cycling and provides real-time humidity monitoring through its LED display.

Key Advantage: The BETA-6 provides simple standalone day/night humidity automation without requiring a central TrolMaster network. Its 20–90% RH range, 5% deadband, canopy-level remote sensor, and photocell-controlled day/night setpoints make it particularly useful where a single 120V humidifier or dehumidifier needs independent humidity control.
