p7 i think is to do with addressing (when 2 indoors on same controller)
check address settings (sw1 think), check cn40 plug is only fitted to master unit.
are there and condensate pump safeties linked over controller cable.
also try resetting both outdoor units ( i once had a p7 phantom in an indian restaurant)
