Control Devices and Function
Major Characteristics
1. Individual/Integrated Operation/Monitoring
You can identify operation status of the air conditioner, operation mode, wind quantity, wind direction, lock-
ing, temperature setting and error, etc by selecting the installed air conditioner through individual selection,
group selection or all selection. Individual setup and operation of the detailed functions are available.
Therefore, managing with Deluxe Central control installed at the control room at a building where a number
of air conditioners are installed, is a convenient way.
2. Group Management
Group management for the installed air conditioners is available. Group can be seperated by their nature,
location and size of each air conditioner which enables convenient use. In addition, allotment of respective
name to the setup group allows further intuitive management.
3. Self-diagnosis Function
The air conditioner installed can self-diagnosed its error status and then transmits the result to the central
control. Therefore, a rapid countermeasure against failure of the air conditioner allows easy management
and increases the usage life of air conditioner.
4. Semi-permanent Life / Convenient Maintenance
Since the Deluxe Central control is designed for the semi-permanent use, this system can be used semi-
permanently after installation, different from the existing PC or a large central control system requiring a
continuous management due to the life of peripheral and other PC.
5. Management Costs Down
In absence of the Central Control System, the manager controls a number of air conditioners. In addition,
even if management was done at the center, there is only function of on/off management at best and thus 2
or 3 building managers were actually required. However, manipulation of all functions can be now done at
a control room for the Deluxe Central control and so a manager can easily control all air conditioners.
Automatic operation is also allowed without a manager, by using schedule function.
