Daikin VRV-IV HR - "H3-05" error
Hi everyone.
Did anybody get the "H3-05" in REYQ-T?
REYQ-T - H3-05.jpg
Classic "H3" - "Malfunction of HP-switch". But for REYQ it is "Connection malfunction main PCB <> inv.2 PCB"
In my case seems to be the "LC-14" - "Transmission error between main PCB (A1P) - inv.2 PCB (A6P)"

Inv.2 PCB A6P was replaced about 1 month ago.Last edited by R666A; 15-12-2021 at 01:22 PM.
