2. Advantage:

• Good interface;

• Simple operation, the product is more intelligent, without explanation can;

• Dual display, can directly see the current temperature and the set temperature;

• Stable and reliable performance, is highly cost-effective multi-functional electronic

  control box.

It has compressor integrated protection function, which can effectively avoid the various danger caused by the instability of current and voltage, to enure safe operation of the device and the safety of goods in the cold storage; integrated protector adopts digital processing technology, which could detect three-phase current and determine whether exists the failure of overload, phase failure, three phase current imbalance, ensuring the stable running of the device; dual temperature sensor could control temperature of compressor and the defrost, safer and more energy efficient; operation panel easy operation; independent function keys, easy operation without the guide of manual; dual display screen, which could intuitively view the current temperature and set temperature, easy to use for end users; crank heating function, which could effectively protect compressor and increase the service life of the compressor. It starts working when the compressor is off, shut down when the compressor starts; internal wiring in the box complies with electrical safety norms. All wirings are marked for easy maintenance. All wiring are performed pressure test or torque test; Box uses thicker metal plate material, paint treatment, moisture proof and shock proof, anti-corrosion, durable.
