An A7 fault will not stop the system from operating but will flash as a fault.
You can also get this error if you forget to connect the wires between the grille and cassette.(the little push clip)

Very Wierd Richard.

I assume it was only the comms and neutral that was incorrect. Normally if this was the case then you wouldn't even get a display on the controller

[rbartlett]

indeed it was and everything worked apart from a7 -which I thought was strange as the flap worked !

I re-wired it and it all worked..??

just thought i would point out as well, that you should test the louvre's in fan only mode, as they will only operate in a thermostat on condition in cooling/heating. Also on old school units sky air series C and D if the louvre motor failed it would hold off the cooling/heating! only way round about it is to replace the motor.
