Daikin multi split system 3 indoor unit and 1 outdoor unit

[Q1000]

Hi
have problem with Daikin multi split system, 3 indoor unit and 1 outdoor unit.
Error codes when system stop are UH,UH and A5.Also when I start one unit, unit is cooling but unit what is on the other side of the wall start but fan is not running so evaporator getting frozen. The third unit is stop . I have checked wiring and all is correct connected. Wires from outdoor terminal strip A goes to indoor unit A and so on. Interesting that when you reset unit by puling down automatic fuse and wait 30 seconds system start again and will work from 12 to 20 hours and will stop with error codes I already explain. Is it possible that pipes from outdoor unit goes to different indoor unit. I will explain what I mean. On outdoor unit you have pipes, liquid and gas, connected to position A and pipes go to indoor unit A, and wires goes to indoor unit A. What if pipes from outdoor unit position A goes to the indoor unit B. Outdoor unit type is 3MXM52N2V1B7 and indoor units are
FTXF20D5V1B.

Thank you for yours advised in advanced.

You need to carry out a cross wiring check as a first option.

Thank you Frank, that is exactly what I have done yesterday and after couple of hours testing one by one unit, found correct wiring. As you can assume my service technician will not get my Christmas greetings card , he was connected wires after repaired small leak of R32 recently.

Thank you for you advice.

There is a built in function for this, you don't have to do it manually.
