1.Temperature display and controlling
2.High quality
3.LED display

Main Function

1.Temperature display, temperature controlling

2.refrigeration/heat mode can be set

3.Compressor start delay protection, sensor error alarm, one external alarm input,

4.Probation time

5.Compared with B20 ,adding to the fan controlling

6.Fan has 2 operation modes,controlling mode and  auto mode 

7.Fan delay start (controlling by both temperature and time ),fan delay stop
