Outdoor unit is detecting error
signal from indoor unit.
Error in receiving serial communication signal.
There is an indoor unit which does not send signals when
the power is ON.

check all the spurs on indoor units- ensure no ring main circuit isolated, check for cut comms cable, inspect each indoor pcb for lil red led

I Had this fault a couple of weeks ago and a indoor unit was isolated at spur.
