Layout and use a variety of home central air conditioning electrical control panel of different central air conditioning cleaning, feature set is not the same, but the operation is basically the same. 1. Select the correct way to run air-conditioning, refrigeration, heating, dehumidification, ventilation, etc., just press a function key on the remote control operation mode on it; 2. How to set the appropriate temperature central air conditioning cleaning, the general temperature of the cooling operation value is set in the range of 20-29 ℃, heating operation temperature setting range is 14-26 ℃ (the set temperature refers to the air conditioner return air temperature or room temperature); 3. test whether the air conditioning compressor normal operation, under normal circumstances when the cooling setpoint below the prevailing setpoint temperature, heating time when the temperature is higher than the central air conditioning multi-line cleaning, the compressor can be running; use of air conditioning installation of air conditioning divisions pipe branch pipes can cross loading or vertical loading, when the angle between the horizontal cross-mounted charge ports shall be less than 15 degrees; when vertical loading, the face of the two charge ports, port charge any angle between the vertical line should be less than 15 degrees; two in charge of opening the tube after Road shall ensure that 60 cm above the straight pipe; small branch pipe does not replace the large branch pipe.
