How to use:
After connecting to the power supply and load (see wiring diagram), you can power the regulator, the red colour manifest for temperature measurement, the following colour blue (or red) as needed to adjust the temperature

If the actual temperature is displayed and please press the set button, the following digital setting text flashes and temperature, after completing the setting, wait for 3 that automatically returns. At this point, the controller automatically disconnects the relay according to the preset temperature, this sensor can meet all kinds of high-performance loads, make sure the line is correct

The status description of the light and digital tube:

Display: This means that the relay is not connected and the normal light indicates that the relay is closed.

Digital tube: LLL sign is the open circuit of the sensor and HHH sign means outside the measuring range, the controller separates the relay violently, the sign means high temperature protection
