When using the P.M.V., the refrigerant flow in the refrigeration cycle will change to an ideal temperature. Control each unit separately by P.M.V. corresponds to the difference in tube length, fan speed and unit temperature. If an error occurs in the temperature cycle when the air conditioner power is turned on, and if the unit starts / stops 30 times, move the valve once until it touches the plug, and position the valve. In this case, a ticking sound will be heard.
