Hi All,
I am trying to decode my AC ir codes, so far i have pretty good understanding of what every command is in the code, at list the ones who’s interesting to me: mode, fan, temp and on/off.
The problem is is that i could not figure the checksum function.
Below is some examples of code i got. The last 4 digits seems to me like a checksum, the first 4 digits are the mode and one bit for power on or off, the second 4 bits are for fan speed the 3rd 4 bits are for temp which in the example below is the only thing that is changed:
cold auto fan, temp:
