Many VRV and VRF air conditioning systems have computer control and an integrated self-diagnosis system. This is necessary to verify the correctness of the system configuration and the correctness of the switching after the installation of the VRV and VRF system is completed. Such software tools can significantly reduce the period of commissioning. But it should always be remembered that the installation of VRV should be carried out only by qualified personnel who have the proper level of training. Convenience is also achieved by the fact that the installation of VRV and VRF systems is carried out both at the construction stage and already during the operation of the building.
