How to use:
After connecting to the power supply and load (refer to the wiring diagram), you can supply power to the controller, the red color manifest to measure the temperature, the following color blue (or red) as required to set the temperature
In case the actual temperature shows and please press the set button, the following digital setting text will flash and temperature, after completing the setting, wait for 3 which will automatically return, at this point the controller will automatically disconnect the relay according to the preset temperature, this sensor can meet all kinds of high power load, make sure the line is correct
The status description of the light and digital tube:
Indicator: off means the relay is disconnected and the normal light on shows that the relay has closed.
Digital tube: LLL sign is the sensor open circuit, and HHH sign means beyond the measuring range, the controller will forcibly disconnect the relay, the --- sign means high temperature protection
Tips
Connect power and load to supply power to the controller. At this time, the upper red display shows the measured temperature and the lower blue (or red) display shows the desired set temperature. Press STC (+) C / F (+) to set the required setting temperature, wait 3 seconds after the setting is completed and automatically confirm the return. At this point, the controller will automatically turn the relay on and off according to the setting. The thermostat output is 10 relays, which can meet the requirements of high power loads. Connection is correct.

The Description of Parameters Function:
Please press the button SET five seconds and then it can enter to the main menu of setting, pressing STC(+)and C/F (-) can switch to P0-P8.
About the adjustment of parameters P0-P8, when you need to adjust P0, firstly please press STC (+) and C / F (-) at the same time, and the P0figurewill flash, secondly please press STC (+)and C / F (-) to adjust, if done, finally please press STC (+) and C / F (-) to confirm at the same time,P1-P8 which can be set the parameters of each code like P0according to the needs of their own.
The key C/F is a key for switching Fahrenheit or Celsius
Press the key C/F once, and it will manifest F(Fahrenheit mode),and then press the key C/F once, it will show C(Celsius mode), the default mode is C(Celsius mode),if there is a big temperature error when you use it, maybe it is F mode.
An example for setting:
If you need to Control the refrigeration equipment
1: Please set into C mode in the code P0:
2:In the case of manifesting the actual temperature you should press the key SET, and the following digital of setting text will flash, then press C/F (+) and SET (-) to set the stop cooling temperature, after setting please wait for 3 seconds, it will automatically confirm to return.
3:Return difference setting: Firstly please press the key SET for five seconds all the time, and it will enter the setting main menu, secondly press STC (+)and C / F (-) to switch into P1, when switching into P1,please press STC (+) and C / f (-)once at the time, the P0 figure will flash, then please press STC(+)and C / f (-)to set to difference value(return difference means that you should add several degrees to start, for instance, if the it stops when the stop setting temperature is 25 degrees, you should need to set the cooling temperature to 28 degrees, the value in the code P1 should be set 3 degrees, so the return difference value is 3 degrees),after finishing that, finally please press STC(+) C/F (-) at the same time to confirm.
4:The above steps are set up, the data is automatically saved, and the final result is, in the control of refrigeration equipment, higher than28 degrees to start the refrigeration, refrigeration to 25 degrees to stop.
If you need to check the heating equipment:
1: Please set to H mode in code P0.
2: In case the actual temperature appears, you need to press the SET key, and the following digital setting text will flash, then press C / F (+) and SET (-) to set the heating stop temperature, after setting please wait 3 seconds, it will automatically confirm to return.
3: Return difference setting: firstly please press the SET key for five seconds all the time, and it will enter the main setting menu, secondly press STC (+) and C / F (-) to switch at P1, when switching to P1, press STC (+) and C / f (-) one time, the P1 digit will flash, then press STC (+) and C / f (-) to set the difference value (return difference means you need to add several degrees to start, for example, if it stops when the stop setting temperature is 25 degrees, you need to set the heating temperature to 22 degrees, the value in the P1 code should be set to 3 degrees, then the return difference value is 3 degrees), after finishing it, press STC (+) C / F (-) simultaneously to confirm.
4: When all the above steps have been set, the data is automatically saved, so to control the heating equipment, it will start the heating system at minus 22 degrees and stop heating when the temperature is 25 degrees.
