So... I'm planning a renovation and am thinking of making the switch to RTI. I like the idea of an XP controller with user control via iPads with RTiPanel and Surfir remotes.

However, my big concern is AC. I'd like to have full room-by-room control of our proposed Mitsubishi or Daikin multi-split AC system via RTiPanel. I was thinking that this could be achieved with a Coolmaster interface box ([Link: coolautomation.com]) via the RTI/Coolmaster driver ([Link: coolautomation.com]).

I've only spoken to one RTI dealer so far and he'd not head of Coolmaster and didn't seem to confident about AC control in general.

Is AC control difficult? What the best / easiest way to achieve it?
