ASTG09 / ASTG12 / AOTG09 / AOTG12 KMTC
Fujitsu GENERAL AIRSTAGE KMTC wall split codes, indoor and outdoor
24 codes
ASTG09KMTC and ASTG12KMTC indoor units with AOTG09KMTC and AOTG12KMTC outdoor units on R32. A compatible non-polar wired controller shows the code directly on its display. The supplied wireless controller has no screen and shows the same codes as a flashing pattern on the indoor indicator lamps instead. The service reference gives a separate main PCB, control unit and inverter assembly identification for each of the two capacities, so a board from the wrong capacity is a recognised cause of codes 32 and 62.
