We have this air conditioner in our sunroom. From

because you have the temperature set at 28 degrees celcuis . Change the temperature to 18 degrees and it will cool 28 is hotter
It is a reverse cycle air conditioner it will warm the room if you set temperature to 28 degrees . Set it lower and it will blow out cold air.
Have exact same air conditioner as I recognise the remote control.
point it at the air conditioner when altering the temperature setting.
Check under the slide compartment also on the remote for more advanced settings.

The run capacitor shorted and blew. This is an oil filled capacitor

06- means short of gas in the system. Call repairman for check and rectify the leak.

try running the air conditioner in defrost mode. set the temperature to warmest while air conditioner is on, for about two minutes. then slowly move the lever towards cold, all the while having the vent set on outside air. once you move it toward cooler, move the vent switch towards recirculate from outside air.

when you have it on defrost, open the engine hood and push the air conditioner button. watch the lines and see if they begin to build frost. if not, move the slider toward cold a little bit at a time while watching the lines to see if they begin to build frost. if they do start to build frost at any point after running the defroster in A/C mode for a bit, you can always try positioning the temperature control towards the middle or run only the outside instead of recirculating vent.

Normally all thermostat calibrated at the end or beginning of -2 or +2 degree difference.

I fyou set 24 degree for cool, it will cut off at the end of 22 and cut in at the beginning of 26degree

Look, if you select a temperature above ambient temperature, it will switch from cooling to heating.(assuming that the aircon has a heat pump. most do these days.) Just dont rush the aircon because every time you make a setting change, it takes a while to regulate.

Make sure the condenser fan and evaporator fan are running. Check your filters. Make sure the coils are not clogged with dirt or dust. Make sure the compressor is running. Get the refrigerant charge checked.

change thermostat.

It sounds like there is a problem with the blower....either the motor itself, the capacitor, a wiring problem or a control problem. If there is a warranty on the unit, have a tech check it out for you.

Let us know if this helps. Good Luck! :-)
