1. STC-8080A+ is a universal temperature controller with single sensor, featuring functions including refrigerating, defrosting, and alarming when temperature exceeds setting limit. 2. Compressor delay protection time is solidified as 3 minutes. When sensor error occurs, the controller starts up and closes according to the solidified proportional time, applicable to industries such as cold storage and refrigerator car. 3. Main functions: Measuring, displaying and controlling temperature. Defrosting cycle and defrosting time are adjustable. Alarm when temperature exceeds setting temperature limit value. Compressor start-up delay protection. Compressor works as scheduled time when sensor error. 4. Model: STC-8080A+ 5. Supply voltage: 220VAC+10%/-15%, 50/60Hz 6. Consumption: less than 3W 7.
