Hi was called to a sanyo 3 pipe eco multi R407-C system today and the master controller was showing a C 06 fault which is apparently a fault with the control wiring. The master controller is the only controller for the system and it controls 18 ducted units. None of which were working I isolated the control panel to gain acsess to the wiring in the panel but when I turned it back on the controller only reconized 3 indoor units? I am thinking that some of the indoor units have lost there mains supply couldn't check today as site was closing just wondered if any one else had any similar problems?
Cheers:D

HI
U sure it was Co6 not E06??????
E06 usually occurs when an indoor loses power and the outdoor cannot communicate with it. Shutting off the master controller should not have made a differance and you should not have lost its memory unless it was rescanned.

Check indoor power supplies and or control wiring connections
Mail me iffn you need any help I know im a bit late with this havn't been online in a while
