MITSUBIHI CITY MULTY problem ... urgent !

[Palkoper]

Hi I am not specialist for MISTUBISHI VRF systems mostly working with DAIKIN and TOSHIBA .
So the system was working 5 years with no problems at all . After maintenance one indoor unit WALLMOUNTED PKFY - P20VBM-E start flashing check 015 6600 error code .( in top corner 1C )

Remote Controller PAR -20 MAA .

So I checked on Mitsi Web site faultcode its mean Ip address doubled . . . ???

Try to change for any different address and still doesnt work . Just still flashing with diferent address .




Replaced all three boards no help .

When disconnected another 4 units from communication its start working but that is not right solution ...

Please anyone know what could be main PROBLEM what should I do to working back all units correct ????

whats outdoor model number?
is there a g50/central controller?
find all units on that system, log address- either at remote or on rotary dial on each indoor,then you should see a duplicate address, then reboot system
