The STC-8080 temperature controller manual from Shanghai Jingchuang details features, specifications, operation, alarm functions and warranty.
The STC-8080 is a compact temperature controller designed for refrigeration applications such as cold storage rooms, seafood pools and refrigerated trucks. It uses a USA Microchip‑PIC microcontroller and offers a range of functions including cooling, automatic and manual defrost, temperature calibration and alarm monitoring.
The manual explains how to set temperature limits, adjust defrost cycles, handle alarm conditions, and perform basic maintenance. It also provides the electrical specifications, environmental limits, and warranty information required for proper installation and safe operation. This manual is written in Chinese.
