I hope you don't mind me jumping into this thread. I too am trying to get a Daikin airconditioner into a format that will allow me to get it into my TSU-7000 and also some more cost effective programmable remote for a number of bedrooms in a house we are currently builing here in Australia. After a number of attempts to get some sense out out Daikin via the Daikin Austraila I realise the only way is down the path you guys are following. The official Daikin line is "we don't give out this information" but get this the local Daikin support guy has said if you find a solution can I let him know as he get this request here in Aus regularly.....a bit off in my oppinion....anyway.
He is where I am at.
1. I have ordered a Daikin multi split system for the new house. 2. The local Daikin dealer who will supply and install the system in Cairns (about 4000kms from where we currently are living) has kindly supplied a remote he had laying around that I could borrow and bring back to play with. 3. I have a TSU-7000 which will not learn the Daikin codes. 4. I have a USB-UIRT IR TX RX and their IRNHELPER ir utility which has enable me to do some Daikin hex capture. I can reliably capture using this system. 5. Unfortunately I don't have a Daikin system to try here (yet) I am looking around I am sure I will be able to sort that out....how convienient it will be to get access at will be the question.
Anyway that said if you want any other codes sent to assist the process please let me know and I will arrange to read and send them. The IR utility indicates the IR frequency and it report hex codes around the 33khz to 33.3khz mark.
I all the searching the net the common thought follows you guys where the code is too long because it send the other setting at the same time.
So the quest I think is to be able strip out the actual command you want and not send the redundant commands. That is providing the Daikin unit lets you!
