This is the user manual for ACR-201 temperature controller, which provides detailed instructions on how to use the product, set up the functions, and check for errors.
The ACR-201 temperature controller is a compact unit that maintains a set temperature using a built‑in micro‑computer and PID control. It can be powered from 86‑250 V AC and supports both PWM and SSR output methods.
The manual provides step‑by‑step instructions for installation, menu configuration, wiring diagrams, default settings, safety markings, error codes and fault‑diagnosis procedures. It also details the recommended sensor types (J or K) and the temperature range of 32 °C – 450 °C. This manual is written in Chinese.

Press and hold the mode key for 3 seconds to switch to standby; the output power is reduced and the standby temperature can be set as a percentage of the set temperature.
Hold the "Set" and "Menu" keys together after changing a value; the controller will automatically save the data.
AL‑H appears when the measured temperature exceeds the high‑limit alarm setting.
