That's really useful, thanks!

The Daikin units I've looked at (and the one I ripped my EEV's from) all had low side pressure sensors, so they use a different control strategy for the compressor speed.



Either way, that Fujitsu SI contains some very useful information (much more so than the Daikin manuals I've looked at).
