Product Details: This digital temperature controller ensures accurate and stable temperature management for diverse uses. Built with durable plastic, it features a compact and lightweight design for easy installation. The unit supports multiple voltage inputs (12V, 24V, 110-220V) and provides precise measurement within a range of -50°C to 110°C, with an accuracy of ±1°C. Its straightforward menu allows quick setup of start/stop temperatures, calibration, and delay timers. Suitable for both heating and cooling modes, it automatically detects the working mode based on your temperature settings. Specifications: - Item Type: Digital Temperature Controller - Material: Plastic - Weight: Approx. 51g / 1.8oz - Operating Voltage: 12V, 24V, 110-220V - Accuracy Level: 0.1 - Temperature Measurement Range: -50°C to 110°C - Temperature Measurement Accuracy: -15°C to 65°C - Humidity Measurement Accuracy: 1% RH - Temperature Measurement Error: ±1°C - Applicable Environment: -15°C to 55°C / 20% to 85% RH - Embedded Hole Size: 73mm / 2.9in (Hole Diameter: φ4mm) How to Use: 1. Press the SET button to enter the menu (default P0). Press SET again and adjust the start temperature using the UP/DOWN buttons. 2. In the menu, switch to P1 using UP/DOWN, press SET, and set the stop temperature. 3. Switch to P2, press SET, and set the calibration temperature. (Note: Calibration compensates for sensor deviation: Detected Temperature + Correction Value = Actual Temperature.) 4. Switch to P3, press SET, and set the delay time in minutes (commonly used for compressor cooling protection; may be skipped if not needed). Temperature Control Modes: - Heating Mode: Start temperature < Stop temperature. Example: To stop heating at 50°C and restart at 40°C, set P0 to 40°C and P1 to 50°C. - Cooling Mode: Start temperature > Stop temperature. Example: To stop cooling at 26°C and restart at 30°C, set P0 to 30°C and P1 to 26°C. Package Includes: 1 x Digital Temperature Controller
