Daikin vrv questions

[philjd26]

Hi gents

Is there an auxiliary output or dry contact for additional
Indication when the system goes into fault??
Need a way of flagging this to external location.

Also noticed the new r410a units a have 4 cables going to inv compressor.. What's the logic and ant information on these???

Thanks phil

To get a remote run an fault signal from the VRV you will need a KRP2A interface board
The 4th wire from the compressor is a feed back signal so the pcb knows the position of the rotor
