Auto addressing technology is adopted for GMV WATER IDU and ODU. No need to set address
codes manually. Only the addresses of master unit and central control are necessary to be set
(address of central control is only necessary when there are multiple refrigeration systems).
When installing remote monitor or central controller, displacement on indoor units’ project codes
should be made. Otherwise, there will be collision malfunction of the project codes. For detail
operation methods, please refer to Installation and Maintenance Manual.
