Semi-permanent Life / Convenient Maintenance I Since the Deluxe Central control is designed for the semi-permanent use. 5. 2. there is only function of on/off management at best and thus 2 or 3 building managers were actually required. location and size of each air conditioner which enables convenient use. In addition. Self-diagnosis Function I The air conditioner installed can self-diagnosed its error status and then transmits the result to the central control. Group Management I Group management for the installed air conditioners is available. even if management was done at the center. Group can be seperated by their nature. a rapid countermeasure against failure of the air conditioner allows easy management and increases the usage life of air conditioner.122 - LGE Internal Use Only . 3. the manager controls a number of air conditioners. is a convenient way. group selection or all selection. temperature setting and error. wind quantity. etc by selecting the installed air conditioner through individual selection.Control Devices and Function Major Characteristics Figure 2) Deluxe Central control 1. However. Therefore. In addition. different from the existing PC or a large central control system requiring a continuous management due to the life of peripheral and other PC. this system can be used semipermanently after installation. Management Costs Down I In absence of the Central Control System. Individual setup and operation of the detailed functions are available. allotment of respective name to the setup group allows further intuitive management. 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.

Especially schedule setting is done by simply by dragging. Upgrade I Additional installation of a new program is available via the CF memory card and the existing program can be upgraded to a new program. 8. since the self-power failure compensation battery is built-in. even if no power is supplied then also all data is saved in the built-in flash memory. and its function can be understood with intuitive pictogram. additional purchase of expensive UPS equipment in provision for a temporary power failure must be done in the past but for the Deluxe Central control. Therefore. it will control the Airconditioners directly while going around the building with the wireless radio system and its self-battery function (100 m where there is no obstacle). middle school. Enlisting of the schedule exception processing schedule (national holiday) is done for a year prevents the air conditioner from an unnecessary operation of air conditioner. allowing the system to be controlled at the center so that it can be only used for a necessary case and enabling to obtain excellent energy saving effect.
