Main Function

Temperature display, temperature controlling(refrigeration/heat mode),compressor start

delay protection, it can run periodically with the on-off rate when the temperature sensor is broken.

2 defrost modes (electric heat, hot gas),

3 defrost start mode (time alternation, accumulativecompressor running time, real time clock),

2 defrost end mode (timing, controlled by both temperature and time), dripping, manual defrost,

7 fan running modes(fan ahead or delay start,delay stop, temperature controlling start and stop, time controlling start and stop, always on,always off, run or stop when defrosting), sensor error alarm,

one external alarm input, password,real time clock, C/F unit change.

 Wiring Diagram

Notice

1 、Please read the guide carefully before using, and set the parameter accurately.

2 、Please place the temperature sensor at the place of air return of the air-cooler.

3. The evaporator sensor must be fixed on the air return pipe of the evaporator, if you don’t

use the evaporator sensor, set the F59 to NO, or the controller will generate alarm.

4 、Please use the temperature sensor which is supplied by our company.
