TrolMaster Digital Day/Night Temperature Controller (BETA-4)

Smart, Reliable Heating & Cooling Control with Independent Day/Night Settings

The TrolMaster BETA-4 Digital Day/Night Temperature Controller is a simple, accurate, and affordable solution for maintaining ideal temperatures in indoor grow rooms, greenhouses, grow tents, and climate-controlled environments. Designed for growers who need precise heating or cooling control, the BETA-4 can operate any device rated 10 amps or less—including heaters, air conditioners, fans, or cooling units.

Equipped with an integrated photocell sensor, the BETA-4 automatically detects day and night cycles, allowing growers to set separate temperature targets for each period. This feature supports more accurate environmental control, reduces stress on plants, and helps maintain optimal conditions for growth across all light cycles.

Using a simple 3-button interface and a clear digital display, the BETA-4 is extremely easy to program. Just plug your heating or cooling device into the outlet on the bottom of the controller, set your desired temperatures, and let the BETA-4 manage your environment automatically. With a built-in fuse, relay output, and long power cord, it offers both safety and convenience.
