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.\u003c\/p\u003e\n\n\n\n\u003cp\u003e• SKU: Beta-2\u003cbr\u003e\n• Input Voltage: 120V AC\u003cbr\u003e\n• Output Switch Type: Triac\u003cbr\u003e\n• Fuse Rating: 6A \/ 250V\u003cbr\u003e\n• Maximum Recommended Load: 4.5A\u003cbr\u003e\n• Fan Speed Control Range: 25–100%\u003cbr\u003e\n• Temperature Accuracy: ±1°F\u003cbr\u003e\n• Temperature Sensor: Remote temperature sensor\u003cbr\u003e\n• Sensor Cable: 16 ft\u003cbr\u003e\n• Day\/Night Control: Independent day and night temperature and fan-speed settings\u003cbr\u003e\n• Photocell: Built-in; automatically detects light\/dark cycles\u003cbr\u003e\n• Temperature Response: Increases fan output up to 100% when temperature rises above the programmed setpoint\u003cbr\u003e\n• Low-Temperature Cut-Off: Fan can shut off when temperature falls below the configured cut-off point\u003cbr\u003e\n• Display: Front-panel LED display with Fahrenheit\/Celsius selection\u003cbr\u003e\n• Controls: HOME, UP and DOWN buttons\u003cbr\u003e\n• Fan Compatibility: 120V AC variable-speed inline\/exhaust fans\u003cbr\u003e\n• Communication: Standalone; not network-integrated\u003cbr\u003e\n• Hydro-X\/Aqua-X Compatibility: Not integrated with Hydro-X or Aqua-X\u003cbr\u003e\n• Package Dimensions: 275 × 87 × 94 mm\u003cbr\u003e\n• Gross Weight: 0.56 kg\u003cbr\u003e\n• In the Box: 1× Fan Controller, 1× Temperature Sensor\u003c\/p\u003e\n\n\n\u003cp\u003eKey Advantage: The Beta-2 provides automatic temperature-driven fan-speed control with separate day\/night profiles in a simple standalone package.
