How to restore factory settings?
Under normal power on state, press and hold the+- keys for about three seconds to restore the factory settings
P0 temperature control mode
When using the thermostat for the first time, this value must be set. If it is used for heating, it should be set to H, and if it is used for cooling, it should be set to C. (Note: H is the abbreviation for Hot in English, C is the abbreviation for Cold in English)
P1 hysteresis setting
Long press the SET button to enter the internal settings, select P1 settings, and then press the SET button again to set the hysteresis value. (The hysteresis is the difference required for the thermostat to resume operation after reaching the set temperature and stopping. For example, if we set it to heating mode, heating to 40 degrees, stopping at 35 degrees, and starting again, the hysteresis is 5.)
P2 temperature calibration
This function is used for temperature calibration. If there is a deviation between the detected temperature and the actual temperature, this function can be used for calibration. The calibrated value=measured value+calibrated value. For example, if we measure a temperature of 25.6 degrees but the actual temperature is 25.8 degrees, we can set P4 to 0.2. Therefore, the final temperature is 25.6+0.2=25.8.
P3 delayed start
This function is generally used for compressor refrigeration. If you purchase this thermostat for use in a refrigerator or freezer, this value must be set. Depending on the back pressure of the compressor, the general setting value is 3-6 minutes. If you are not controlling the compressor or do not need the delay function, simply skip this option.
P4 high temperature alarm
Set a high temperature alarm value, and when the real-time temperature exceeds this value, the screen will flash to prompt an alarm!

| 3.出廠默認回差是2℃，要想溫度降到30℃C再次加熱，需要將回差值設定為5。長按SET鍵進入內(nèi)部設定，選擇P1，將P1值改為5，到此就設定完成了 3. The default hysteresis value at the factory is 2 ℃. To lower the temperature to 30 ℃ and reheat, the hysteresis value needs to be set to 5. Press and hold the SET key to enter the internal settings, select P1, change the P1 value to 5, and the settings are now complete | 3.出廠默認回差是2℃，要想溫度回升到27℃再次制冷，需要將回差值設定為4。長按SET鍵進入內(nèi)部設定，選擇P1，將P1值改為4，到此就設定完成了 3. The default hysteresis value at the factory is 2 ℃. In order to cool again when the temperature rises to 27 ℃, the hysteresis value needs to be set to 4. Press and hold the SET key to enter the internal settings, select P1, change the P1 value to 4, and the settings are now complete |
