7.1.1 Introduction to Remote Monitoring System
The great development of Gree’s technology for manufacturing commercial air conditioners enables Gree to provide
remote monitoring system for Gree commercial air conditioners to users which can solve the problem of difficulty on
centralized management and maintenance caused by complex and disperse distribution of commercial air conditioners in
a building. Users can execute daily management and maintenance to the units by the system which is easily operated and
reliable.
Combining with technologies for electrommunication and computer software, remote monitoring system of Gree
commercial air conditioners can collect information, inspect running status, and execute control and error warning of
the commercial air conditioners. It can apply with a variety of types of commercial air conditioners, such as Multi VRF
Units, Centrifugal Units, Air-Cooled Screw Chiller, Water-Cooled Screw Chiller, Closed Control Units, Modular Units,
and Air Duct Type Units, etc. It can also meet the requirements of various building projects in the aspect of centralized
management and monitoring for commercial air conditioners, which is indispensable high-tech product for intelligent
control and information-based management of the modern building.
7.1.2 Function Instruction to Remote Monitoring System
Remote monitoring system of the Multi VRF units can remote monitor all models of Gree current luxury Multi VRF
units. In comfortable ofce, user can centrally manage and control max. 255 sets of Multi VRF units by software installed
in monitoring computer. Specic models applied with the system are:1-16 indoor units of Multi VRF units, R410A heat
recovery, single unit inverter of Multi VRF, modular Multi VRF units, 900 digital Mutli VRF, R22 digital heat pump units,
1-32 digital Multi VRF units.
It is capable of remotely turning on/of the unit, modifying the mode, changing the settings, altering the fan speed, and
enquiring the status of the unit etc .through the remote monitoring system/BMS system.

7�2 BMS System
7.2.1 General Description of BMS System
The BMS system of Gree’s central air conditioner adopts RS485 communication mode and provides the prevailing
MODBUS protocol. Via MODBUS standard protocol interface, Gree’s central air conditioner can be seamlessly interfaced
to the building management system (BMS).
This system is applicable to centralized monitoring and management of GMV multi VRF system, water cooled screw
chiller, air cooled scroll chiller and centrifugal chiller. It is a requisite system for managing the intelligent air conditioner
system in modern buildings.
The BMS of GMV multi VRF system can provide BMS interface for Gree’s multi VRF system. Via this interface, the
user can execute centralized management and control of 4080 indoor units under 255 sets of GMV multi VRF systems. It is
a requisite system for management of the intelligent air conditioner system in modern buildings. This system is applicable
to the following models: 1-16 GMV indoor unit, R410A Heat Recovery Unit, Non-modular Inverter GMV, Modular GMV,
900 Digital GMV, R22 Digital Heat Pump Water Heater and 1-32 Digital GMV.
