Function description：
1.Refrigeration, Heating, Cold and Hot control：
C Under the refrigeration mode:
Present temperature a≥Target temperature b, into the refrigeration state, Present temperature a≤(Target temperature b-Return difference temperature c), into stop status. (For example, If you want to control the temperature between 10～15℃. Temperature rises to 15℃，Start compressor, Temperature drop to 10℃ stop it, Press S to enter setup, Set target temperature b is 15℃, Set return difference temperature c is 5℃, It can keep the temperature between 10~15℃)
H Under the heating mode:
Present temperature a≤Target temperature b，into the heating state, Present temperature a≥（Set temperature b+ Return difference temperature c），into stop status. (For example, If you want to control the temperature between 30～35℃, Temperature rises to 35℃, Stop heating equipment, Temperature drop to 30℃ , starting heating equipment. Press S to enter setup, Set target temperature b is 30℃, Set return difference temperature c is 5℃, It can keep the temperature between 30~35℃)
CH Cold or Hot mode:
Present temperature a≥Target temperature b+ Return difference temperature c，into the refrigeration state;
Present temperature a≤Target temperature b- Return difference temperature c，into the hesting state;
Present temperature a≤Target temperature b，Stop refrigeration equipment，
Present temperature a≥Target temperature b，Stop heating equipment.
(For example, If you want to control the temperature between 5～-5℃，Temperature rises to 5℃，Starting refrigeration equipment，Temperature drop to -5℃, Starting heating equipment.Press S to enter setup,，Set target temperature b is 0℃, Set return difference temperature c is 5℃，It can keep the temperature between 5~-5℃)

3. Set target temperature
Under normal state, short press (SET) button and display is flicker, display the target temperature B at this time. Press + or - button to adjust the temperature, Short press SET button once again to save exit after the adjustment was completed.
