Disconnect all power before wiring. Improper wiring will destroy the unit or cause fire. Refer to the sticker on top of the actual unit, as terminal assignments vary by manufacturer clone.
This comprehensive manual provides the technical specifications, panel configurations, wiring layouts, and parameter adjustment guidelines required to install and program the controller safely and effectively. Technical Specifications

: Used to cycle through menu trees, initiate configuration adjustments, and finalize numerical parameters.
Based on the model number , this device is a standard Digital PID Temperature Controller (often used in incubators, 3D printers, and industrial ovens). These devices are widely manufactured by various Chinese brands (such as REX, Wenzhou, or Yudian), but they all share a very similar interface and wiring scheme. Disconnect all power before wiring
is a digital temperature controller often used in industrial machinery like plastic molding machines, ovens, and packaging equipment. It typically features an LED display for both the measured value (PV) and the set value (SV). Made-in-China.com Key Specifications Input Types:
| Symptom | Most Likely Cause | Solution | | :--- | :--- | :--- | | | No power, internal fuse blown. | Check the external AC 220V supply. If voltage is present, replace the unit (internal fuse may be non-serviceable). | | "HHH" or "LLL" Error | Sensor failure or wrong input type. | Check if the wire to the probe is cut. Check if the menu input type (Sn) matches the actual sensor used (e.g., Pt100 vs K). | | Temperature reading is inaccurate | Loose thermocouple connection or need for temperature offset. | Tighten sensor terminals. Use the SC parameter (Input Correction) to add an offset value. For example, if the display reads 2°C lower than actual, set SC to "2.0". | | Relay is clicking rapidly | Hysteresis (return difference) is set too low. | Increase the HY or dF parameter (usually set between 1 and 5) to stabilize control. | | Unit trips the circuit breaker | Heater shorted or internal relay shorted. | Disconnect the output wires. If the breaker still trips, the unit is dead. If not, check the heating element wiring. | Down Arrow ( ↓down arrow ): Decreases the
Proportional band (3-6%) may need adjustment, or the sensor may be placed too far from the heating element. 4. Safety Precautions Ensure the power supply is disconnected before wiring.
