Hello Johnsfine,

The power off button on your original remote sends two commands. The second command turns it off. If I understand correctly, you don't know what (if anything) the first command does.

You are right! I do not now what the 1st command does.

I hope it is safe to use just the second. Maybe the first does some sort of prepare_to_turn_off function that avoids stopping it in a bad state and/or turning off two many parts at once (causing a power surge).

I understand.

Hello Robman,

Try these hex codes for the 2 temp buttons...

temp up
45 7F 8D 49 D8 0F

temp down
4D 7F 8D 41 D8 0F

I will test them tomorrow ant let you know the result.

temp up

temp down
4D 7F 8D 41 D8 0F

They do not work as expected. They are effective for only a single up(from 24 to 25) or down(from 25 to 24), all the time, whether a single key press or multiple key presses, same result.

Here are the hex codes for all 10 temp buttons that you captured using CaptureIR...

temp up
80 4D 7F 84 C9 D8 0F
80 45 7F 8D 49 D8 0F
80 45 7F 8D 49 D8 0F
80 45 7F 8D 49 D8 0F
80 45 7F 8D 49 D8 0F
80 45 7F 8D 49 D8 0F

temp down
80 43 7F 84 C1 D8 0F
80 4D 7F 8D 41 D8 0F
80 4D 7F 8D 41 D8 0F
80 4D 7F 8D 41 D8 0F
80 4D 7F 8D 41 D8 0F
80 4D 7F 8D 41 D8 0F

As you can see, the first capture of each was different to the rest. Maybe that first code puts the unit into a mode ready for the 2nd code in the set. So try creating 2 buttons for each function, then press the part1 button first and then press the part2 button to keep changing the temp.

temp up
4D 7F 84 C9 D8 0F - part1
45 7F 8D 49 D8 0F - part2

temp down
43 7F 84 C1 D8 0F - part1
4D 7F 8D 41 D8 0F - part2

[The Robman]

Maybe the temp is controlled using discrete codes also, here are the 12 unique temp codes that you have posted so far...

43 7F 84 C1 D8 0F down
45 7F 84 CB D8 0F down
45 7F 84 CD D8 0F up
45 7F 8D 43 D8 0F down
45 7F 8D 45 D8 0F down
45 7F 8D 49 D8 0F up
49 7F 8D 47 D8 0F up
49 7F 8D 4B D8 0F up
49 7F 8D 4D D8 0F down
4D 7F 84 C3 D8 0F up
4D 7F 84 C9 D8 0F up
4D 7F 8D 41 D8 0F down

Try creating buttons for each of these and then test them to see what happens.

[yesok]

Hello Robman,

temp up
4D 7F 84 C9 D8 0F - part1
45 7F 8D 49 D8 0F - part2

temp down
43 7F 84 C1 D8 0F - part1
4D 7F 8D 41 D8 0F - part2

Both of them give same result as before - only single up or down.

All of them shows the same result as before - only signle up or down.

What would you suggest to try next?

Yesok

[The Robman]

All of them shows the same result as before - only signle up or down.

That's what I was expecting when I suggested that they were discrete codes, in other words, each of them will advance you to a single temperature. Does your unit display the temp setting numerically, and if so, how many different temp settings are there?

Try this, set the unit to the lowest possible temp setting, then start learning the temp up buttons from the remote, learn the button as many times as there are temp settings. Then repeat the process learning the temp-down button.

When you're done, try using the learned signals, remembering to press them in the same order that you learned them.

Hello Robman,

Yes. from 18(the lowest) to 30(the highest) settings.

Try this, set the unit to the lowest possible temp setting, then start learning the temp up buttons from the remote, learn the button as many times as there are temp settings. Then repeat the process learning the temp-down button.

I have uploaded 2 files - one for temp ups(see https://www.hifi-remote.com/forums/dload ... le_id=4435) and one for temp downs(see https://www.hifi-remote.com/forums/dload ... le_id=4436)

When you're done, try using the learned signals, remembering to press them in the same order that you learned them.

I will do that tomorrow, and let you know the result.

All temp up and down buttons are working!

One problem is I am unable to save KM upgrade file. Maybe Korean version of Win XP SP2 is responsible. I have uploaded complete KM v9.08 (see https://www.hifi-remote.com/forums/dload ... le_id=4444) with discrete temp up and down buttons. Could you save the upgrade and post it?

Now the question is how to reduce the number of buttons for temp up and down control.

Thanks again for your valuable support.

That's good.

Sure

Now the question is how to reduce the number of buttons for temp up and down control.

Do the temp buttons each only work as "UP only" or "DOWN only" buttons? In other words, if the temp is current set to 20, would the "22>21" code work to change the temp to 21 instead of the "20>21" code? If so, that would reduce the number of temp buttons in half. In fact, I notice that some of the "down" codes are the same as the "up" codes, so I'm guessing that this is the case. Try these codes...

4D 7F 84 C4 D8 2F - temp 18
45 7F 84 CC D8 2F - temp 19
4D 7F 84 C2 D8 2F - temp 20
45 7F 84 CA D8 2F - temp 21
45 7F 84 C6 D8 2F - temp 22
49 7F 84 CE D8 2F - temp 23
45 7F 84 C9 D8 2F - temp 25 *
4D 7F 84 C1 D8 2F - temp 24
45 7F 84 C5 D8 2F - temp 26
49 7F 84 CD D8 2F - temp 27
45 7F 84 C3 D8 2F - temp 28
49 7F 84 CB D8 2F - temp 29
49 7F 84 C7 D8 2F - temp 30 *

(* the codes flagged with an asterisk are experimental codes)

Thanks again for your valuable support.

You're welcome.

Here's a couple more experimental codes for you to try...

4D 7F 84 C7 88 2F Air Clean - On
43 7F 84 C7 88 0F Air Clean - Off
43 7F 84 C7 D8 2F power on

Also, if you get the chance, could you re-learn several samples of the following buttons for me please...

Deflector Left/Right On
Deflector Up/Down On
Cool Mode - Far
Cool Mode - Turbo
Timer Cancel
Timer Set

Thanks for the extra learns, they clarified some things. When you test the other codes that I posted, could you test the codes listed below to verify that they perform the deflector tasks listed. It appears that the "off" code for left/right and up/down is the same.

4D 7F 84 C7 A8 0F - L/R & up/down off
43 7D 84 C7 A8 0F - L/R on
47 73 84 C4 D8 0F - L/R on
4B 75 84 C7 A8 0F - up/down on
47 75 84 C4 D8 0F - up/down on

The following codes are probably duplicates of the ones above, but please test them anyway...

45 7F 8D 47 A8 0F - L/R & up/down off
4D 7D 8D 47 A8 0F - L/R on
4B 73 8E 44 D8 0F - L/R on
43 75 8D 47 A8 0F - up/down on
4B 75 8E 44 D8 0F - up/down on

I'm seeing 4 unique codes for "Timer Set", could you test whether test all do exactly the same thing or whether some of them perform a slightly different function...

4D F0 80 00 20 00
4D F1 00 00 20 00
45 FC 00 00 20 00
