Mairong Hi-Tech air conditioner shows that the indoor temperature is too high and gives an alarm.

1. Because there is an induction probe on the air conditioner to sense the temperature near the air conditioner, and the temperature near the air conditioner is close to the air outlet of the air conditioner, the temperature must be higher (heating)/lower (cooling) than the indoor temperature. The bigger the room, the more obvious this situation is, so it can only be used as a reference figure. It is normal if the temperature you want and set is not accurate, but it is normal anyway. 2. For example, for refrigeration, set the temperature to 18 degrees. At this time, the air conditioner only blows cold air with the greatest strength, so that the temperature of the whole room will drop. When the indoor temperature drops and the induction probe mentioned above detects that the room temperature is almost the same as the set temperature, the air conditioner will stop running, and so on. Therefore, it is normal for the display to be inaccurate.
