The MT-4896 PID+Fuzzy Temperature Controller provides artificial‑intelligence based control with selectable PID, fuzzy, and auto‑tuning modes. It supports multiple input types, relay, voltage‑pulse, and 4‑20 mA outputs, and offers RS‑485 communication for remote monitoring and configuration.
The manual details the controller's general specifications, parameter settings, alarm configuration, communication protocol, and command structure, enabling users to install, configure, and operate the device safely and efficiently.

The controller operates from a 90 V to 265 V AC supply at 50 Hz or 60 Hz.
The device accepts PT‑100 temperature sensors, selectable from the input menu.
It supports RS‑485 communication with selectable baud rates (600 bps or 19200 bps) and 16‑bit data frames.
Press the auto‑tuning key for about three seconds; the controller will enter auto‑tuning mode and adjust parameters automatically.
