Hitachi Set Free
Big probems with the RAS 30 FSN Set Free (utopia split system)
We had some problems with error code 51 (inverter problems) but that we bypassed with the dipswitches. We have 32 units on one external unit, so 16 normal and 16 viritual units, problem now is that the power was out on the unit for 2 days and after that when we started it up again the viritual units indicates a error (on 14 units)
(63) Communication Alarm Indoor never detected.
and on 2 we got
(61) Communication Alarm. Indoor stoped coummunication
(06) Power failure AT IU, Reset
Does anyone know something about this?
