Instruction:
Normal mode: The red digital tube on the left shows the real-time temperature, the blue digital tube on the right shows the set temperature.
Setting mode: The red digital tube on the left displays the setting mode, the blue digital tube on the right displays the setting contents.

Code Instruction:
Code Function Default Set Range
Start or Stop Temperature 0°C/68°F -50~120°C/-58~248°F
P0 Working mode H H/C
P1 Difference set value 2 0.2-10
P2 High temperature alarm value 80°C/176°F -50~120°C/-58~248°F
P3 Low temperature alarm value -50°C/-58°F -50~120°C/-58~248°F
P4 Temperature calibration value 0 -10.0°C~10.0°C
P5 Compressor delay time 0 0-60Min
P6 Display mode C C/F

P0: working mode
This setting is mainly set to the value when the thermostat is used for the first time. If it is used for heating, it should be set to H. If it is used for cooling, it should be set to C.
P1: hysteresis setting
The hysteresis is the difference required when the thermostat reaches the set temperature and stops working again. For example, if we set the heating mode to a temperature of 37-40 degrees, then the difference is 3
P2: high temperature alarm value
When the temperature reaches the set value, there will be an alarm action and stop working.
P3: low temperature alarm value
When the temperature is lower than the set value, there will be an alarm action and stop working.
P4: temperature correction
These functions are used for temperature calibration. If there is a deviation between the detected temperature and the actual temperature, some functional effects can be used. The positive value = measured value + corrected value. For example, we measure the temperature at 25.6 degrees and actually 25.8 degrees. P4 can be used. Set to 0.2 then the final temperature is 25.6+0.2=25.8
P5: delayed start
This function is generally used for compressor refrigeration. If you purchase some thermostats for the refrigerator freezer, this value must be set. According to the compressor back pressure, the general setting is 3-6 minutes.
P6: C/F conversion
If you want to change to F value, change the unit to F, the unit display light is on. If you want to change it to C value, change the unit to C, the unit display light is not bright. If you want to convert quickly, exit the display, long press You can quickly convert units by adding 3 seconds.
