PART 1 ENGINEERING DEBUGGER

1 OVERVIEW

With quick increase of comprehensive constructions and large buildings, central air conditioning
systems of the buildings are not only increased in number and diversified in model but also sparsely
distributed, which makes centralized management and maintenance difficult to realize. Gree Debugger,
integrated with electronic communication technology and PC software technology, helps monitor, control,
and debug central air conditioning units all round, making sparse distribution not an issue and realizing
centralized control and management. Managers, needless to go to the site to set and manage all units,
can perform running state query, unit start/stop, temperature adjustment, and other operations using a
PC, improving working efficiency and reducing manpower, material, and management input.
At present, Gree Debugger can be used to comprehensively monitor and control Gree Ultra Heat
GMV units. So long as users have a PC, they can monitor and control air conditioning units through the
software. Gree Debugger is an effective intelligent management tool for air conditioning systems and
also a tool for engineering setup and after-sale debugging. With Gree Debugger, users can debug air
conditioners on site, understand units' running state, and conveniently analyze units' health conditions,
not only improving users' working efficiency and reducing maintenance difficulty and cost but also
improving customers' service quality and speed.

2 SYSTEM NETWORKING

Gree Debugger is applicable to single-system network. In a single-system network, the software can
control both IDUs and ODUs.

2.1 Composition of System Network

From the network topology, it can be seen that Gree debugging network is composed of three parts:
Control PC part in the monitor room, including Gree Debugger and USB Converter Driver installed in
the PCs.
USB data conversion part, mainly converts air conditioning units' communication mode into PC
recognizable mode. Devices include USB data converters and USB data lines.
Air conditioning unit part, mainly composed of air conditioning units, including ODUs, IDUs, and lines.
If the lines are not long enough, the transfer board accompanied with Gree Debugger can help connect
the lines together. In a single-system network, the converter can be connected to an IDU or an ODU.
