4, fault tips:
1) When the sensor is disconnected, the display shows --- and close the heating wire
2) When the sensor detects the temperature lower than -50 degrees, the display shows the LLL
3) When the sensor detects a temperature above 110 degrees, the display shows HHH

 

5, Caution:
* Cooling, heat load must not exceed the output contact, or may cause machine damage and cause a fire.
Disaster.
* A variety of connection wires and terminals connected to pressure well, otherwise, will cause the machine reliability.
* Please separate power wiring, relays, sensors, otherwise it will damage the machine.
