Unable to Control Samsung Heat Pump

I got ahold of an G Cache WiFi I.R. mostly in the hope controlling my Samsung heat exchanger. It has what I would refer to as an "integrated" IR remote controller which is used to control the unit / adjust setpoints, etc. It also has a display on it as well. It is "stupid" enough though that if you took it to another room and changed the setpoint, it would show as changed on the remote but of course it has not really changed because the IR code did not actually reach it (I think each temp setpoint may be it's own code as opposed to just up and down). Anyways I digress... I seem to be able to capture what I would "loosely" call a valid code (once every 5-6 tries and only on a few buttons)....but when I send it, the unit beeps, as it does when sent a command from the real remote, but does not actually do anything. i.e. send the power on/off code, but it neither powers up or down.....just beeps I've captured and controlled my home entertainment system but no luck on this front. Can anyone point me in the right direction...what the frig are all the gap/module/connector etc settings used for (on the Cache). Is there any good reading out there ? Do I need codes directly from Samsung or something ? Any assistance is GREATLY appreciated ! PLCG

  We have found that air conditioner/heater/heat pump codes are often exceptionally long because they are compiled based on the entire set of settings of the unit. You may be having problems because the code you are sending is not the entirety of the coding necessary to command the hardware. Have you manipulated the Gaps setting when learning the code to capture more data? If not, then that might be the problem. Try incrementing the gaps setting and testing before saving the code.

  Also, contacting the manufacturer is also not a bad idea. If you are unable to get the codes from the manufacturer it is also possible that you may be able to find them on an online IR code index website like www.remotecentral.com

  Hi Gents
  
  I'm posting this on both the "iTach" and "Universal Devices" forums because I posted this question on both sites.
  I also hope someone else may possibly benefit from my experience.
  
  This issue has been resolved. My problem was this...the iLearn utility for the iTach WF2IR was reading the correct
  IR string (playing with the gaps setting seemed to make it more repeatable)...and quite a long string at that....but
  when you "Send IR" from the iTach utility it appears to automatically "trim" the string....therefore making it quite
  useless (removes valid information). There ought to be a way to send out exactly what you captured..... Anyways
  on a whim, I cut/pasted the "un-trimmed" captured string into my network resourses in the ISY99i, fired it off to the
  iTach, and BINGO.
  
  Yes indeed these are very long strings and contain all the settings for the unit...example: When you hit a
  "temperature setpoint up 1 degree" key, it is sending the updated temperature setpoint as well as operating
  mode, flap setting, fan setting, etc etc etc. Therefore any IR string captured from the original remote is a
  "picture" of all the unit settings on that keypress (or something close to that).

  Anyways, thanks for all the great hardware and support.
