panasonic 3 phase split
a panasonic (r22) split system has threw up a fault code of f 30 (only one split being controlled of the controller) . the manuel states that there is a problem with the outside unit. to cut a story short the voltage across the red and blue phase is 1.5v but between red/yellow and yellow/blue are both 415v . this is even the same at the dis board (tried disconnecting the s.w.a. feed to the isolator but still the same). if any one could explain how this could accour and what effect it will have to the condensing unit.
