Feature Highlights: 1. Easy Operation & Clear Display – Just plug it in, choose heating or cooling mode, and it starts working—no complicated setup. The LCD screen shows real-time temperature with accurate, easy-to-read numbers. 2. Precise Temperature Control – Measures from 50°F to 99°F with a resolution of 0.1°F. Accuracy stays within ±1°F in common conditions (-20°F to 60°F), so you get reliable, consistent results. 3. Dual System Support – Can connect to both heating and cooling devices at the same time. Separate differential settings for each system help maintain steady temperatures even when conditions change. 4. Smart Safety Features – Includes temperature alarm for over-limit warnings or sensor errors, plus compressor delay protection to extend equipment life. Temperature calibration is also supported for fine-tuning. 5. Wide Compatibility & Use – Works with 100–250V power supply and supports up to 16A max. Ideal for greenhouses, fish tanks, heaters, incubators, home temperature control, and various farm or hobby applications.Product Details: This digital temperature controller offers plug-and-play convenience with a clear LCD display. It allows precise management of both heating and cooling systems, with adjustable differentials for each mode. Built-in alarms and compressor protection help prevent equipment damage, while wide voltage compatibility and a broad temperature range make it versatile for home, farm, or greenhouse use.Specifications: - Measuring Range: 50°F–99°F - Resolution: 0.1°F - Accuracy: ±1°F (-20°F to 60°F) - Power Supply: 100–250V, 16A max - Display: LCD screen - Functions: Heating/Cooling mode, dual system support, separate differential settings, temperature alarm, sensor error alert, compressor delay protection, temperature calibration - Applications: Greenhouse, aquarium, heater, incubator, farm, home temperature control, and more
