3. ACP operation by using the LG ACCS Controlling the demand power It maintains the consumed power to be kept lower than or equal to the target power by monitoring the wattage of the air conditioner. It can control to save the energy by using the demand controller connected to the ACP forcefully to start or stop the air conditioner. It has the following advantages: • Precise management by controlling the automatic operation ratio of the air conditioner with the demand controller. • Monitor and control the peak power for 24 hours a day. • Easily perform controlling and monitoring. Note: Peak operation ratio control & Demand control The ACCS offers the peak operation ratio control function and the demand control function to reduce the power cost by operating all air conditioners less than or equal to the permitted demand power. One of the peak operation ratio control function or the demand power control function can be used depending on the function setting of the ACP, but two functions cannot be used together. This section describes the method for controlling the demand power. For more information about the peak operation ratio function, see Chapter 3. 'Controlling the peak operation ratio'. When the air conditioner forcefully operates by the demand power control function, the air conditioiner cannot be individually managed because the automatic central control is used. However, when the current operation uses the power less than or equal to the target operation ratio setting, the air conditioner can be individually managed. Installation/Owner's Manual 3-51
