How to set the stop heating temperature?  Connect the power supply and the heating pad correctly according to the wiring diagram, connect the red and black to the power supply, and the yellow and black to the heating pad. After the connection is connected, power on and display the real-time temperature, press the set button once, and when the screen starts to flash, press the up and down buttons to set the stop temperature you want. After setting, wait 5 seconds or directly press the OK button to save the data.  2. How to set the restart temperature?  After stopping at the set stop value, the restart temperature is the stop set by you.  For example, if you set the stop at 38 degree with a difference of 0.1degree, then it will be heated again after it stops at 38 degree and drops to 37.9.  3. How to expand the setting range? The factory default setting range is 20-39.5 degree. If you first set 20-45 degree, set P1 to 45 degree. If you want 24 degree for the lowest temperature, set P2 to 24 degree. P1 and P2 are combined. Setting is to limit the setting range to prevent incorrect setting.    4. How to correct the inaccurate temperature measurement? If there is a temperature measurement error, it can be corrected. For example, if the temperature is displayed as 30 degree and the actual temperature is 30.3 degree, adjust P3 to 0.3 degree. For example, if 26 degree is actually displayed as 25.5 degree, adjust P3 to -0.5 degree.  5. How to set high temperature and low temperature alarms?  Eggs have very high requirements for temperature during the incubation process. Exceeding the range will affect the success rate of incubation. P4 and P5 are high and low temperature alarm settings. For example, the high temperature is set to 42 degree and the low temperature is set to 35 degree. At 42 degree or lower than 35 degree, it will give an alarm to remind the handling measures.
