Conventional Temperature And Humidity Controllers LY-W2K

Product Advantages

Heating Precision & Response Speed

With a temperature accuracy of ±0.5℃ and a control backlash of 0~20℃, the LY-W2K can maintain the target temperature within a narrow range, avoiding overheating or insufficient heating. Its fast heating response design enables quick temperature recovery in low-temperature environments, reducing energy waste and improving efficiency.

Dual-Sensor Safety & Reliability

Equipped with Dual Temperature Sensors (Sensor 1 & Sensor 2), the controller monitors temperature in real time from two points, ensuring data authenticity. If one sensor fails, the system automatically switches to the backup sensor to prevent heating interruption—a key safety feature for temperature-sensitive applications like vaccine storage. The built-in temperature alarm also alerts users promptly to abnormal temperature changes.

User-Friendly & Long-Lasting Performance

The intuitive user interface with clear "Power/Temperature 1/Temperature 2" indicators and simple button controls allows for easy setup without professional training. Its industrial-grade durable construction resists corrosion and temperature fluctuations, ensuring stable operation in harsh environments (operating temperature: -20℃~70℃; relative humidity ≤95%RH) for long periods.

Technical Specifications

Heating-Optimized Technical Focus

The LY-W2K’s technical parameters are optimized for heating performance: it uses AC 220±10% 50Hz power supply, compatible with global industrial standards; the temperature control range of -9℃~99℃ covers most low-temperature heating needs; the 3A dual working voltage load capacity supports various heating devices (e.g., electric heaters, heat lamps). Its <2W low power consumption reduces operational costs.

Detailed Parameter Breakdown

Applications

Cold Storage Supplementary Heating

In food cold storage, pharmaceutical cold chain warehouses, and vegetable greenhouses in cold regions, the LY-W2K provides supplementary heating to maintain the minimum safe temperature (e.g., 5℃ for fruits, 2~8℃ for vaccines), preventing freezing damage and ensuring product quality preservation.

Industrial Manufacturing Heating Processes

In plastic molding, metal processing, and chemical reaction processes, the controller regulates the temperature of production equipment or materials to ensure consistent process conditions, avoiding product defects caused by temperature variations and improving production efficiency.

Pharmaceutical Temperature-Sensitive Storage

For temperature-sensitive drugs (e.g., insulin, biological agents) in pharmacies, hospitals, and pharmaceutical warehouses, the LY-W2K maintains a stable storage temperature, complying with national pharmaceutical storage standards and ensuring drug efficacy and safety.

Laboratory Heating Experiments

In microbial culture, chemical synthesis, and material performance testing experiments, the controller provides precise and stable heating conditions, ensuring the accuracy and repeatability of experimental results, making it an indispensable tool for scientific research.

Selection Guide

Heating Demand Assessment

Choose the LY-W2K if your application requires active heating (not just temperature monitoring) or operates in low-temperature environments (e.g., northern industrial workshops, winter cold storage). For humidity-priority scenarios, select the LY-S2K instead.

Input Module Compatibility

Pair the controller with the ALE-W2K input module (designed for 2 temperature inputs) to enhance temperature signal collection accuracy and control responsiveness. Ensure the heating load power matches the controller’s 3A load capacity to avoid equipment overload.

Critical Application Alarm Options

For high-risk applications (e.g., vaccine storage, precision manufacturing), add the disconnection alarm function to receive instant alerts if heating elements or sensors fail, preventing irreversible losses caused by temperature deviations.

Operation Guide

Power & Hardware Connection

Power Wiring: Connect AC 220V power to terminals 6-10 (AC input) and terminal N (neutral wire); verify the "Power" indicator lights up to confirm successful connection.

Heating Load & Sensor Installation: Connect heating equipment (e.g., electric heater) to the load terminals; mount Sensor 1 and Sensor 2 near the heating target (avoid direct contact with heating elements) for accurate temperature detection.

Temperature Threshold Configuration

Enter setup mode by pressing the "Auto/Manual" button; set the heating upper limit (e.g., 25℃) and lower limit (e.g., 15℃) according to application requirements.

Confirm the settings and exit setup mode; the controller will automatically activate/deactivate the heating load based on real-time temperature readings.

Regular Inspection & Calibration

Sensor Calibration: Calibrate both temperature sensors every 6~12 months using a standard temperature calibrator to maintain measurement accuracy.

Load & Wiring Check: Monthly inspect the heating load connection for loose wires or overheating; clean the sensor surface to remove dust and debris affecting temperature detection.

Alarm System Test: Quarterly test the alarm function by adjusting the temperature beyond preset thresholds to ensure timely alerts for abnormal conditions.
