Hi,
when configuring comfort to send IR codes learned from my remotes i found that that all my appliances only work when i extend the IR cable and point direcly to the receiver, about 1 meter distance. Even for one of the A/C (Fujitsu) i installed the receiver about 1 meter LOS and it does not always work.
My tested appliances are:
2 different Fujitsu A/Cs
LG TV
Panasonic TV
I troubleshooted with a IR receiver that turns on a led each time i detects signals and i have verified that it is possible to even receive wall reflected signals, my guess is that the original appliances find the signal too low and discard it.
I\'m kind of confused, is this the expected behavior? do i have to install a IR transmitter right in front of each of my appliances? Am i missing something?
I can try the outputs on the main comfort to see if there is any difference. I\'d be grateful if someone could share with me some tips on this, since i was expecting a performance similar to the original remotes that work almost in ever angle/position.
My set up:
- comfort Ultra II 7.005
- UCM USB 7.002
- UCM KNX 6.024
- RIO 2.007
- 13 16A relays - finder 40.61
all in the same enclosure powered with the original 12Vac transformer that came with the bundle.
- SCS 6button about 5 meters away
Best regards,

Which IR Transmitter do you have?
IRM01
IRM01 is a long range transmitter, which is similar range to a handheld remote control ie 5 to 8 meters
IRW01
IRW01 is short range transmitter about 1 meter range
IRW03
IRW03 is a short range transmitter meant to stick on to the receiver
You need the IRm01 for long range operation
There is no difference between RIO and Comfort/SEM/LEM outputs

I had this problem as well using the IRM-01 with my aircon
i ended up cabling to each unit and fitting the irm-01 in a little box on the ceiling see photo
it looks horrible but it wouldnt work anywhere else

Hi, i have 8 IRM01\'s longe range.
- slychiu - 01-16-2013
The IRM01 should be able to work at a distance, not just 1 meter
Have you tested all 8 IRM01 with the same problem?
Are the IRM01 connected direct to the RIO Output with no addtional resistance?
How long is the cable from the IR transmitter to the RIO?
Can you try connecting to a Comfort Output just to make sure the RIO is not faulty

Hi, thanks for the answers.
I\'m afraid my issue looks similar to what wiredhome described. Anyway i\'ll test all IRM01\'s at both RIO and comfort and report back.
I can describe how i bumped into this, maybe it can help:
- Direct connection from RIO to IRM1 using 1 pair of 5 meter CAT5e cable (for testing).
- Originally the A/C OFF IR code worked at +- 3 meters away but no other IR code.
- relearned all the codes but only the OFF worked
- streched the cable almost to the position of the IR receiver of the A/C and all the learned codes worked ok.
- Performed the same tests in another room, with the same results.
- tested at least 3 different IRM01 and 2 different RIO outputs. Connected 12v lamp through the RIO outputs and they work ok.
What i find strange is that i can \"see\" my standalone IR receiver detects the IRM01 signal, after it has been reflected on a wall, about 5 meters total distance and right on target with the appliance original IR receiver. But the appliance don\'t like it.
Is there any way i can increase the IR led power?

\"- relearned all the codes but only the OFF worked\"
Use a fresh set of batteries in remote control when learning IR. Sometimes it makes a lot of differences.

let me rephrase this:
\"- relearned all the codes but only the OFF worked\"
- relearned all codes from the commands, but didn\'t do any difference. Only the \"OFF\" code was successfuly aknowledged by the A/C.
Since the IRM01 works at short distance i assume that there is no issues with the IR learning process.
Hopefully i will resume troubleshooting this weekend.
Thanks

Quote:\"- relearned all the codes but only the OFF worked\" - relearned all codes from the commands, but didn\'t do any difference.You mean that these are the results after changing to a fresh set of batteries for the remote?

Since the IRM01 works at short distance i assume that there is no issues with the IR learning process.
If so try to downgrade to an older UCM firmware 6.024 attached, as some changes were made to IR learning after that version
- cab123 - 01-20-2013
No, sorry, the batteries are new and never experienced any problems during the IR learning process.
I\'ve been testing this weekend and understand better my problem.
The IRM01 does indeed transmit IR codes long range, my problem was that i was expecting a performance similar to a remote but its not the case.
the IR led needs to be extremely well positioned to work, for exemple, at 4 meters distance, if i point the led to the IR receiver of my A/C (right edge) it works. If i point it to the other edge of the AC it doesn\'t work. The AC is 80cm wide. Just for fun i tried to understand what was the limit and found out that the IR transmitter can be directed to about 30cm off target. From 4metes distance... uh too lazy to do the math, but the angle is extremely narrow!
So probably it is fuctioning as designed.
Now i have to install more IR transmitters, can you please advise on how many IRM1\'s can be installed in parallel on one output? I would\'t like to waste too much outputs.
