Auto addressing technology is adopted for
System 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 Potovoltaic Multi VRF Installation and
Maintenance Manual.
