USB-UIRT, Homeseer and Daikin multisplit airco

[musca]

Hi,
I have the following problem and I would be very grateful if somebody can help. Here it goes:

I have installed in my mother house a multisplit airco system made from 5 Daikin indoors units (two FVXS25FV1B units and three FTXS25G2V1B units), all of them linked to one outdoor unit. All five indoors units are operated by the same type of remote (ARC452A3).



Here are the links to the installation/user manuals:

What is my goal: to allow my mother to control the Daikin using the USB-UIRT device and Homeseer. USB-UIRT and Homeseer are already installed and working fine (lighting and other devices that use IR). If full control is not possible al least some basic commands like unit on at 20C low fan, unit off, etc.



What I have tried until now:

I tried to learn the IR codes from the Daikin remote using 2 different types of high end learning remote controls (Philips sbc ru880/00 and Onkyo rc1407628/05). Both remotes learned the codes without any errors. Both remotes transmitted the code to the Daikin unit without problems also, but the Daikin unit didn't react at all. I tried learning only the off command from the Daikin remote but same result.

I did the same thing using USB-UIRT. Open the Learn Helper Utility application, learn IR code ( I have tried several times the Off command) , got the code into the "IR code (Pronto format)" window. When I transmit the code to the Daikin unit it doesn't react at all.

Here is the code I got:

0000 0070 0000 007F 0081 0041 0010 0031 0010 0011 0010 0010 0010 0011 0010 0031 0010 0011 0010 0011 000F 0011 0010 0011 0010 0031 0010 0011 0010 0031 0010 0031 0010 0010 0010 0031 0010 0031 0010 0031 0010 0031 0010 0031 0010 0011 0010 0011 0010 0031 0010 0011 000F 0011 0010 0011 0010 0011 0010 0010 0010 0011 0010 0011 0010 0011 000F 0011 0010 0011 0010 0011 000F 0011 0010 0011 0010 0011 0010 0010 0010 0011 0010 0011 0010 0011 000F 0011 0010 0011 0010 0011 0010 0031 0010 0010 0010 0011 0010 0011 0010 0011 000F 0011 0010 0031 0010 0011 0010 0031 0010 0011 000F 0032 000F 0011 0010 0011 0010 0011 0010 0010 0010 0011 0010 0011 0010 0011 000F 0011 0010 0011 0010 0011 0010 0010 0010 0011 0010 0011 0010 0011 000F 0011 0010 0031 0010 0031 0010 0011 0010 0011 000F 0011 0010 0011 0010 0011 0010 0010 0010 0011 0010 0011 0010 0011 000F 0011 0010 0011 0010 0011 0010 0010 0010 0011 0010 0011 0010 0011 000F 0011 0010 0011 0010 0031 0010 0031 0010 0011 0010 0010 0010 0011 0010 0011 0010 0010 0010 0011 0010 0011 0010 0011 000F 0011 0010 0011 0010 0031 0010 0031 0010 0011 0010 0010 0010 0011 0010 0011 0010 0011 000F 0011 0010 0011 0010 0011 0010 0010 0010 0011 0010 0011 0010 0010 0010 0011 0010 0011 0010 0011 000F 0011 0010 0011 0010 0031 0010 0011 0010 0010 0010 0011 0010 0011 0010 0F13

I can understand we are talking about a dynamic code here, but I was expecting at least Off command to be static and simple. What I am doing wrong here ?



Help would be highly appreciated,

Thanks
