Daikin FFQ50BV1B + RXS50BVMB.
Fault Code U4, seems to be bad communication.
Strange phenomena: on same main power supply but on a different breaker, the VD controlled compressor (grounded) of a VRV failed also this morning.
For the Daikin pro's: what do you think, change both (in- and outdoor) PCB boards?
Does someone has the manual of FFQ50BV1B and RXS50BVMB
