2. Installing ACP
Before installing the ACP
ACP provides 4 RS485 ports to connect the indoor unit. Maximum of 16 units can be connected to
PI485 for outdoor unit in 1 RS385 port, and maximum of 31 units for SINGLE/Ventilator PI485.
256 indoor units at maximum can be connected to one ACP. All of 256 indoor units may be connected
to one RS485 port, which is the maximum number of units for the ACP to connect. But, in order to
improve the communication performce of the RS485, we recommend to distribute them to four ports.
Note: Change the number of connections of RS485
If it is inevitable to change the above specification, call the system air conditioner support division
By considering three following cases using the ACP, perform the installation after carefully considering
how to use.
• Install the single ACP to use as web server
• Connect the single ACP to the AC Manager to use
• Connect more than one ACP to the AC Manager via the hub to use

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.
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'.
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.

Twisted
copper line
The Unshielded Twisted Pair (UTP) cable is
a sort of the signal line connecting the LAN
environment. Two copper lines insulated for
reducing the electromagnetic induction
between two lines are twisted to form the
twisted pair.
The UTP cable consists of 8 wires, of which four lines (No. 1 and 2 for receiving (Rx) and No. 3 and 6
for transmitting (Tx)) are actually used for the data transmission at the general LAN environment. It
can be largely classified two types according to the method for connecting the line for receiving and
transmitting.
Direct cable
It is also called the 1:1 straight cable used for connecting the other equipment at the network.
Cross cable
It is used for the 1:1 connection between the same equipments at the network.
