This was googled: waves error codes
It showed a page in "images". Stated
"System abnormity" I think. Page was blurry.
Call a tech! Mini splits can be a troubleshooting nightmare! I think its a Fujitsu unit. It would help, and may save you some $$, to call around to find a technician who has worked on mini splits. And maybe find them a 1-800 # that is their tech support # before hand, so if the tech needs it, you have it. E4 is a vague description for a fault. Make sure you have cleaned air filters, cleaned o.d.coil (turn off power at breaker 1st). Changed batteries in remote. Work safe!

To change from Cecilius to Fahrenheit on the remote control, hold both the + and the - simultaneously and this will enable you to toggle between C and F. You will need to do this each time you change your batteries.

The "head unit" mounted on the wall shows you the current room temperature. On your remote it shows what temperature you are trying/want to achieve.

If the units are close to each other they will both read the same setting. You just have to get the remote really close to the wallmont air handler you want to command.

Sounds like a common problem I have found with Samsung mini split unit. When powering on, does the internal blower attempt to start, then the unit stops and lights blink? If so, on the circuit card there is a 1.2uf or 1.5uf (CBB61) that probably has gone bad. I have replaced several of these. Good luck.

One thing you need to check is Polarity. the 2 wires red and white, need to be on the same terminals inside as they do outside. this is very important.

Centigrade (celcius) metric temperature .
19C = 66F, 20C = 68F 21C= 70F approx.
25C= 77F, 30C = 86F. There should be a setting to change that to Fahrenheit.

1. use remote properly
2.first off the unit then again the unit
3 if same problem change remote by new one

I do not suspect the remote, I think it is the return air sensor on the evaporator coil. If you can remove the plastic cover that encloses the coil do so and vacuum the coil and any sensors you may see. I suspect that a technician will have to perform a resistance test on the sensor.
