I have a new Daikin VRV III with about 15 indoor units. Have had u4 issues show up 3 times. First time just reset everything and it worked for a month. Next time they suggested replacing all the control wiring at the indoor units which they supposedly did. It happened again so they replaced the pcb on the outdoor unit.
It has not happened yet but today one of the indoor units had a flashing red light which one time before was a precursor to the whole system going on a u4 - after a few days I found all the units flashing red lights and the noticed the u4 code on the master.
Today I switched the flashing unit off and on and it seems to be fine but based on my previous experience something is going to go wrong in a few days I am sure.
Has anyone else experienced this and have a solution? I am just the user so will want to feed any ideas to the technicians who I have already made aware of this latest issue.
Thanks.
