4.7.4 Communication address
Auto addressing technology is adopted for photovoltaic Multi VRF IDU and ODU. No need
to set address codes manually. Only the addresses of master unit and central control are
needed to be set (address of central control is only needed when there are multiple
refrigeration systems).
NOTICE! When installing remote monitor or central controller, displacement on indoor
units' project codes must be made. Otherwise, there will be collision malfunction of the project
codes. For detail operation methods, please refer to the GMV5 Installation and Maintenance
Manual.
