1.Temp measure & control:-50~+50celsius
2. Dual-sensor 
3. Control compressor,fan,defrost 
4. Defrost thermal & electric heating Protection

General descriptions:
ECB-30 is a new optimizing product especially designed for refrigerant units. Double-sensor control, control three-load synchronously, proper and complete protection functions. Easy-to-operate, stable and reliable performance. ECB-30 is an Electric Control Box with multi-functions and rather high performance versus price ratio

Functions and features:
1. Three -load control, can control compressor, fan, defrost independently.
2. Double temperature measuring sensors to independently control the temperature of compressor and defroster, more safe and economic.
