TrolMaster Digital - Digital Day / Night Fan Speed Controller (BETA-2)

TrolMaster Digital - Digital Day / Night Fan Speed Controller (BETA-2) is a digital day/night fan speed controller for temperature-based fan speed control in enclosed grow spaces using variable-speed fan control.

BETA-2 automatically increases or decreases fan speed based on the current temperature, helping you manage heat more efficiently without running full power all the time. When temperatures rise, it boosts cooling by raising fan speed. When temperatures fall, it reduces cooling capacity by lowering fan speed. This automatic fan speed adjustment creates a steadier environment, with smoother ventilation changes that can be easier on equipment and simpler to monitor day to day.

Day-night control is built in. A built-in photocell sensor detects day and night status and allows the controller to manage fan speed differently between day and night periods. That makes it a practical fit for rooms that benefit from distinct environmental targets across a full cycle, while still keeping control focused on a single task: reliable fan speed management.

Operation is designed to be straightforward, with an LED display for clear readouts and simple adjustments. A remote temperature sensor provides the temperature input used for the controller’s fan speed behavior, keeping readings consistent as conditions change in the space.

This fan speed controller is suited for growers who want a simple, economical way to deal with heat using a dedicated controller that responds to temperature and automatically manages ventilation output. If your setup depends on variable-speed fan control and you want clear day-night control plus temperature-based fan speed control in one compact unit, the BETA-2 keeps airflow management clean and predictable.
