As the temperature rises, fan speed increases to enhance cooling; as it drops, fan speed decreases to conserve energy. This unit features an easy-to-read LED display, day/night temperature settings, and a built-in photocell that automatically detects light cycles. A 16-foot temperature sensor allows accurate monitoring near your plant canopy for optimal climate response. Whether you're managing heat buildup or improving air exchange, the BETA-2 offers a cost-effective, reliable solution.
