NA210 Temperature Controller User Manual, the main functions include temperature display, temperature control, compressor start delay protection, temperature probe abnormal alarm and other functions. The temperature display range is -50～125°C, and the temperature setting range is -45～120°C.
The NA210 controller provides heating and cooling temperature control with features such as temperature display, set‑point limits, compressor start‑delay protection, and sensor fault alerts. Technical specifications include a temperature display range of –50 °C to 125 °C, a setting range of –45 °C to 120 °C, and a 3 A/250 VAC output contact capacity.
The manual explains normal operation, how to adjust upper and lower temperature limits, and how to access advanced parameter settings using a password sequence. It also includes wiring diagrams, safety notes, and guidance on sensor placement and grounding. This manual is written in Chinese.

The display shows “EE” when the temperature sensor is short‑circuited; “‑EE” indicates the sensor is disconnected.
Enter the password sequence “up‑down‑up‑down‑up‑up‑down‑down” by quickly pressing the “^” and “v” keys within three seconds; the display will show “Fxx” and allow parameter adjustment.
