Product Function diagram

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!
