Pin no.
According as the surface temperature of the panel, enter the optimum 3 bit signal into pin No.4, 5 and 6.
Measuring the correlation between detected temperature by the sensor on PWB in user’s side and actual
surface temperature of panel at center, convert the temperature detected by the sensor to the surface
temperature of panel to enter the 3 bit temperature data.
For overlapping temperatures (such as 5°C, 10°C, 15°C, 20°C, 25°C, 30°C, 35°C) select the optimum
parameter, judging from the actual picture image.
