STC-8080A+ is a universal temperature controller with a single sensor, designed for applications including refrigeration, defrosting, and temperature alarm functions when limits are exceeded. The compressor delay protection time is fixed at 3 minutes. The controller operates based on a fixed proportional time in case of sensor error, making it suitable for use in cold storage, refrigerated vehicles, and similar environments. Main functions: temperature measurement, display, and control; adjustable defrosting cycle and defrosting time; high/low temperature alarm; compressor start-up delay protection; compressor operation at scheduled intervals during sensor failure.
