Daikin professional after-sales answer for you. Yours may be a fixed frequency air conditioner, and the temperature difference of one or two degrees is normal. Don't dwell on it. Maybe the insulation effect of your room is not good enough to reach the set temperature, then the constant frequency compressor will keep running. If you are in doubt, you should ask him to measure the air temperature of your air conditioner. If it can reach 13 14 degrees, it will be basically normal.
Please accept it, thank you!
