My Split system AC has an error code that I cannot understand or find anywhere online. There is no technician available in my area to come out and troubleshoot my AC system. My AC has an error code and my AC is not blowing cold air. Is there a way to completely reset the split system AIRCON and attempt to clear the error code? My AC is not working right now and it is the hottest time of the year.

I have an Air Con system. It has and error code of HS or H5. It will not blow cold and the snowflake representing cold keeps blinking. I’m melting in S.Florida please help!
Thank you.
I have a AIR-CON series BLUE 2 18,000 BTU’s.
I am almost positive that using the A/C mode last year in the auto mode when I set the temp for 74 degrees (or any temp) that when it reached the temp, the unit would stop blowing till the room got warmer then come on again.
Now this year I don’t feel it doing that, it will just blow the air.
I called AIR-CON one guy said to disconnect power for hour and let him know it worked, I called back to say no and another guy said the unit DOES NOT WORK that way.
Why would they have AUTO version and also fan speed hi-med-low?
