Function


Setting range:

P0 Starting temperature:-50℃~110℃
P1 Stop temperature:-50℃~110℃
P2 Temperature correction:-10℃~10℃
P3 Delayed start:0~10min

Introduction to code and features:
P0 sets the startup temperature
Press the SET button to enter the internal menu. The default display is P0. Press the SET button again to set the desired start temperature with the up and down buttons.
P1 sets the stop temperature
Press the SET button to enter the internal menu. The display is P0. Press the up and down button to change to P1. Press the SET button again to set the desired stop temperature.
P2 set temperature correction
In the same way, enter the internal menu, change to P2 by pressing the up and down buttons, press the setting button again, and set the required calibration temperature by the up and down buttons (detection temperature + correction temperature = actual temperature)
P3 set delay start
In the same way, enter the internal menu, change to P3 by pressing the up and down buttons, press the setting button again, and set the required delay time by the up and down buttons, the unit is minute. (Note: Delay start is generally used for compressor refrigeration. If English refrigerator freezer, this value needs to be set. According to compressor back pressure, it is generally set for 3-6 minutes. If it is not used to control compressor refrigeration, it does not need to be extended. Time function, skip directly.)
Heating mode: starting temperatureCooling mode: starting temperature > stop temperature (program automatically determines cooling mode)
