3. ACP operation by using the LG ACCS
Controlling the peak operation ratio
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 forcefully starting or stopping the air
conditioner according to the specified peak operation rule.
It has the following advantages:
• Centrally control all installed air conditioners by using the computer screen.
• Monitor and control the peak operation ratio for 24 hours a day.
• Easily perform controlling and monitoring.
• Set the peak control function by wattage (kW) or operation ratio (%).
• Control the operation switching period (5~15 minutes) of the air conditioner.
• Set the exceptional air conditioner not to apply the peak operation ratio control function.
The air conditioner forcefully operating by the peak operation ratio control function operates at the
ventilating mode during the cooling operation while the operation stops during the heating operation.
But, the user's inconvenience due to setting the peak operation period is minimized.
When the air conditioner forcefully operates by the peak operation ratio 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.
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 peak operation ratio. For more information
about the demand control function, see Chapter 3. 'Controlling the demand power'.
Caution: When the ACP is interconnected with the AC Manager
When the ACP is interconnected with the AC Manager, set Demand as ACP setting.
The ACP operates according to the demand setting of the AC Manager.
