The TrolMaster Beta-2 is a standalone digital fan-speed controller designed for variable-speed 120V inline and exhaust fans in enclosed cultivation spaces. It continuously adjusts fan output from 25–100% based on live temperature readings from the remote sensor, while its built-in photocell automatically switches between independently programmed day and night temperature and fan-speed settings. It requires no hub, network connection, subscription, or additional timer for standalone operation.

Key Advantage: The Beta-2 provides automatic temperature-driven fan-speed control with separate day/night profiles in a simple standalone package. Its triac-based 25–100% speed modulation avoids basic relay-style ON/OFF cycling, while the built-in photocell automatically changes operating parameters between lights-on and lights-off periods.
