Can any one help me with this chiller, its the first time ive worked on a daikin chiller.

i had the call for the chiller not working at all, when i arrived the controller had 2 alarms which was +C2 OFFMTRPROTECT and +C1 OFFMTRPROTECT

After further investigation i found that one of the 80amp fuses had blown on circuit 1, i removed the fuse and took the compressor offline so circuit 1 is currently running on 2 compressors.

After about 1/2hour of running i get the +C2 OFFMTRPROTECT alarm again and it shuts circuit 2 down, i have looked online and im not able to find what the fault code is or means.

The controller is also asking for a password which we dont have (just taken site over) without calling daikin applied out to investigate is there anyone on here that has experience or knowledge of these chillers?
