Product Details: This digital temperature controller is your go‑to tool for consistent climate management. Built for reliability, it lets you set custom temperature ranges for heating or cooling mode. The clear menu makes setup straightforward: set your start and stop points, calibrate for accuracy, and add a delay if needed for compressor protection. It’s versatile enough for a water heater, an aquarium, a fermentation chamber, or a seedling heat mat—anywhere you need dependable temperature control. Specifications: Product 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 Operating Environment: -15°C to 55°C / 20%‑85% RH Panel Cut‑out Size: 73mm x 73mm (2.9in x 2.9in) Mounting Hole Diameter: φ4mm How to Use: Basic Settings: 1. Press the SET button once to enter the menu (default P0). Press SET again and use the UP/DOWN buttons to set your desired Start Temperature. 2. From the menu (P0), use UP/DOWN to switch to P1. Press SET and use UP/DOWN to set your desired Stop Temperature. 3. From the menu, switch to P2. Press SET and use UP/DOWN to set the Calibration Temperature. (Tip: If the sensor reads 0.5°C higher than actual, set calibration to -0.5°C. Detected Temperature + Correction = Actual Temperature.) 4. From the menu, switch to P3. Press SET and use UP/DOWN to set a Delay Time in minutes (mainly for compressor protection in refrigeration). Temperature Control Modes: Heating Mode: Start Temperature < Stop Temperature. Example: Keep a water heater between 40°C and 50°C. Set P0 (Start) to 40°C and P1 (Stop) to 50°C. Cooling Mode: Start Temperature > Stop Temperature. Example: Run a cabinet fan when temperature hits 30°C and stop at 26°C. Set P0 (Start) to 30°C and P1 (Stop) to 26°C.
