Hello Robman,

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
49 FD 00 00 20 00

Please wait a few day more for my test result.
I will be out of town until next Monday.

Sorry for the delay.

Hello Robman,

Please find the test result.

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 *

All of them working.

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

Air Clean On and Off are working, while Poqwe On is not working.

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 - O.K.(plus Air Clean Off)
43 7D 84 C7 A8 0F - L/R on - O.K.
47 73 84 C4 D8 0F - L/R on - O.K.(plus U/D On)
4B 75 84 C7 A8 0F - up/down on - O.K.
47 75 84 C4 D8 0F - up/down on - O.K.

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 - O.K.(plus Air Clean Off)
4D 7D 8D 47 A8 0F - L/R on - O.K.
4B 73 8E 44 D8 0F - L/R on - O.K.(plus U/D On)
43 75 8D 47 A8 0F - up/down on - O.K.
4B 75 8E 44 D8 0F - up/down on - O.K.

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
49 FD 00 00 20 00

All of them are working. All of them lights up a timer icon on the Air Conditioner panel. But it is not clear when their operation end, since it takes long time(upto 24 hours).

I have uploaded new learned IR files(see https://www.hifi-remote.com/forums/dload ... le_id=4473).

Here are my new findings about timer operation;

Under Power On status, pressing Timer set/cancel button, after pressing timer reserve button(no IR signal, just internal operation), from 1 to 27 times, set/cancel timer operation, resulting automatic power off after predefined time delay(from 0.5 to 24.0 hours).

Under power off status, timer will power on automatically.

Hope I am not asking too much of your effort.

4D 7F 84 C7 A8 0F - L/R & up/down off - O.K.(plus Air Clean Off)

4B 75 84 C7 A8 0F - up/down on - O.K.
47 75 84 C4 D8 0F - up/down on - O.K.

So would I be right in assuming that you could make do with this the following two codes from this group...

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

Also, I made a typo with the POWER ON code, here's another version for you to try...

Please note that other timer power on/off codes are not yet tested. It takes time to verify that they do work. One need to wait until the timer expires. I will test them as time allows.

Hey Yesok,
Good to hear from you again. Don't worry too much about the timer codes, if the first couple in each set are working, it pretty much verifies that the concept works.

Now I just need to gather all the data together to see if I can make the upgrades a bit smaller.

Hello Robman,

Don't worry too much about the timer codes, if the first couple in each set are working, it pretty much verifies that the concept works.

I am much relieved to hear this. Testing all the timer codes may take a few weeks.

Now I just need to gather all the data together to see if I can make the upgrades a bit smaller.

Good news.

I made a typo in the "cool mode far" code, here's the real code...

4B 7D B4 C1 88 0F

and here are some new codes for the temps...

45 7F 8E 44 D8 2F - temp 18
49 7F 8E 4C D8 2F - temp 19
45 7F 8E 42 D8 2F - temp 20

I noticed that several of the codes for different functions are actually the same. Take a look at the following list to see if it makes sense to you? For example, when you set the temp to level 30, do you expect the fan to go to "high" mode and the cool mode to go to "normal"?

45 7F 84 C7 D8 0F
temp 30
Fan - High
mode - cool
Cool Mode - Normal

4D 7F 84 C7 A8 0F
