STC-8080A+ is a universal temperature controller with single sensor,specify all the functions as refrigerating,defrosting,alarming when temperature exceeds setting limit. Compressor delay protection time is solidified as 3 minutes,Controller start up and close according to the solidified proportional time when sensor error,which can be applied to the industries such as cold storage,refrigerator car,etc. Main functions: To measure,display and control temperature. Defrosting cycle and defrosting time is adjustable. Alarm when temperature exceeds setting temperature limit value. Compressor start up delay protection. Compressor work as scheduled time when sensor error.
