    The main difference between HR VRV 2 and VRV 3 is that the switching time between cooling and heating changeover has been greatly reduced.

    VRV III can still provide heating while carrying out a defrost. Single module units - REYQ**P - have two seperate coils and compressors, so while it uses one comp to defrost one coil the other comp is still able to provide heat to indoors, once the first coil has completed its defrost the operation is reversed to defrost the other coil. On multi module systems - REMQ**P - one mode defrosts while the other one or two modules supply heat to indoors, again the modules swap once the defrost is completed.
