SOURCE: LG Art Cool, 2 splits. Error code CH7

Multi Splits and Multi V = indoor unit is set to run in a different mode from the master indoor unit. Set ALL indoor units to cooling or ALL to heating to clear.
Splits = Compressor Over Current (CT2)

SOURCE: I get a CH2 error

From the limited information that I could find on this item, CH2 is a temperature error.

Sorry I couldn't find out enough information to really be of any help.

My lg ac colling good but after 15 to 20 minutes run of all systems and display show CH05

Here is an answer from official LG site:
The CH05 error message means you have an indoor / outdoor unit communication error. It can be caused by any of the following issues:

No power on indoor unit
Indoor/outdoor unit power connection error / communication line not installed
Communication error caused by external noise
Indoor/outdoor unit communication circuit parts burned.

In my opinion if it works for some time and then shows the error it may be communication error caused by external noise.
You should contact the trained technician to deal with that problem.
