Adding a new model of heat pump (already decoded)

[Fardenco]

I've been decoding the output of the remote from a Hyundai heat pump, and I think I figured the function of each byte.
Heat, cool, dry, temp, fan speed, programming, swing and sleep, everything seems right.

This is for a portable AC unit, which is reversible to output heat. It's a Hyundai hy-clm12kr
Here is a typical IR code :

0001|1000 | 18 | 00011000 never seems to change
1010|0001 | 85 | 10000101 temp change, cool
0000|0001 | 80 | 10000000 No programming, Celcius, no sweep, normal mode, fan speed 1
0001|1000 | 18 | 00011000 24 degrees
0000|0000 | 00 | 00000000 no programming
0000|0000 | 00 | 00000000 never seems to change
0100|0110 | 62 | 01100010 checksum

We have 7 bytes, the last one seems to be the checksum
Here is what I found

0001|1000
kkkk|mmmm
dusn|ffff
tttt|tttt
hhhh|hhhh
0000|0000
cccc|cccc

kkkk : 1010 temperature change, 1000 mode change / on, 0000 off.
mmmm = mode : 1000 heat, 0100 fan, 0010 dehumidification, 0001 cold
d = time programming, 0 = off, 1 = on
u = unit : 0 = C, 1 = F
s = sweep : 0 off, 1 on
n = sleep : 0 normal, 1 sleep
ffff = fan speed : 0001 = 1, 0010 = 2, 0100 = 3
tttt = temperature, unit is specified before
hhhhhhhh= time programming in hours, up to 24
cccccccc : checksum, simply the sum of all previous bytes, truncated to fit 8 bits

The only doubt I have is regarding the kkkk bits, I don't fully understand their role, they change depending on the action done on the remote but I suspect they are not always used to do anything
They are used to switch off the unit, that's for sure, but beside that they seems useless even if the value changes depending of what I do. For example if I hide the remote when pressing power on, and then I change the temperature, the code is for a temperature change but the unit still turns on.

Could you please add this to your library ? Thanks
