Yellow

Hi All, Just joined to say thanks for the info you've all shared. I've succesfully installed my AX-09 now As it still wasn't clear to me how to set it in cooling mode, i tried the A4 terminal which was suggested a couple of pages back. And, i'd like to share some new info too: With 24v on the A1 and A4 terminals (And A5, for negative of course) we have cooling too, woohoo. Cheers!
