Hi , i have installed VRF system by AUX ,all units are working well in cooling mode, the problem in heating mode
if we start some units and the others are off , these units give a high noise , sound of hot gas in coil , if we put them on ( ON ) the noise will disappear , as i know in heating mode if the unit was off the EEV will be opened at minimum position but it has not to give this disturbing noise ?????
