★ After power failure, press and hold the + and - keys simultaneously to power on and display 888, which will restore the factory settings.

Operation example:
● Heating mode
Example: Turn the radiator heater to 60 degrees and stop. After stopping, it will start again at 50 degrees. It needs to be set to the heating mode, with a temperature tolerance of 10 degrees. The settings should be as follows:
1. When the temperature is displayed normally, press the SET button once to make the temperature flash.
Set the stop temperature value to 60.
2. Press and hold the SET button to display P0 and set the working mode to H.
3. Set the P1 tolerance value to 10. 

● Cooling mode
Control the refrigerator to stop when the temperature drops to -5℃, and resume cooling when the temperature rises to 0℃. The settings should be as follows:
1. When the temperature is displayed normally, press the SET button to make the temperature indicator flash and stop the temperature value at -5℃.
2. Press and hold the SET button to display P0 and set the working mode to C.
3. Set the P1 deviation value to 5. 

★ How to set the stop temperature?
When the thermostat is powered on, it displays the real-time temperature. Press the SET key once and the screen will flash. Use the up and down keys to set the stop temperature.
★ How to enter the internal settings?
Press the SET key for 5 seconds continuously.
★ P0: Working mode
When using the thermostat for the first time, the mode must be set. If it is used for heating (low-temperature start, high-temperature stop), it should be set as H. If it is used for cooling (high-temperature start, low-temperature stop), it should be set as C.
★ P1: Offset setting
Press the SET key to enter the internal settings, select P1, and press the SET key again to set the offset value. (The offset is the difference needed for the thermostat to start working again after reaching the set temperature. For example, if we set the heating mode to stop at 40 degrees and start again at 35 degrees, the offset is 5.)
★ P2/P3: Limit setting values (non-temperature control)
P2 limits the maximum setting value (non-temperature control), and P3 limits the minimum temperature control value (non-temperature control). For example, set P2 to 50, and the stop temperature can only be set to 50 at most.
★ P4: Temperature correction
This function can be used to correct the deviation between the detected temperature and the actual temperature. The actual temperature value = thermostat measurement value + correction value. For example, if the thermostat measures a temperature of 25.6 degrees but the actual temperature is 25.8 degrees, set P4 to 0.2, and the final displayed temperature by the thermostat will be 25.8 = 25.6 + 0.2.
★ P5: Delay start
This function is generally used for compressor cooling. If you purchase this thermostat for a refrigerator or freezer, this value must be set. The general setting value is 3-6 minutes based on the back pressure of the compressor. If you are not controlling the compressor or do not need the delay function, simply skip this item.
★ P6: High-temperature alarm
Set the high-temperature alarm value. When the real-time temperature exceeds this value, the screen will display - - - to indicate an alarm. The high-temperature alarm value must be greater than the stop temperature value to be effective.
