The TrolMaster BETA-4 is a standalone, single-outlet temperature controller designed for cultivation environments requiring separate day and night temperature setpoints. Its built-in photocell automatically detects the light/dark cycle, while the included 16-ft temperature sensor monitors conditions at canopy level. The controller can operate either a heating or cooling device up to 10A, with a 5°F deadband to help prevent short-cycling.

Key Advantage: The BETA-4 provides simple, photocell-aware day/night temperature automation for one 120V device without requiring a full environmental-control system. Its 16-ft sensor can be positioned at canopy height, while the 5°F deadband helps reduce rapid ON/OFF cycling.
