5-2-1 Initialization of the PLC (When the PLC is in use)
Before using the PLC Software for demand input or Electric Amount Count Software, click on the PLC initialize
button once to initialize the internal memory.
Note: Do not initialize the memory after the operation has begun, for it will clear all operation data.
5-2-2 Setting the PLC software for demand input (demand input method)
(1) Enter the IP address for the PLC software for demand
input.
(2) Enter the IP address of the G-50A to which the demand
levels are reported. A maximum of 10 addresses can be registered.
5-2-3 Setting the Electric Amount Count Software (Electric power monitor method)
(1) Enter the IP address of the electric amount count software.
(2) Enter the unit of the pulse that the watt-hour meter outputs.
Note: If the pulse unit field is left blank, there will be no change to the
pulse unit; only the information that was entered in the IP address
and DI board field will be saved.
(3) Select the terminal number of the DI board to which the watt-hour meter is connected. If it is connected to
terminal 2 on DI board 1, select 1-2.
Note: Select an input board from either 1 or 2, and select an input terminal from 0 to F. Choose the terminal to which the watt-hour
meter is connected that is used for peak cut.
5-2-4 Setting the Control Level (Electric Power Monitor Method)
Determine the range of electricity use for each control level (demand
level), taking into consideration such factors as delayed control of the
air conditioner. Enter the value that is 10 to 15% below the maximum
demand value (average electric energy value in 30 minutes) in the
blank next to Level 4. Decrease the value by about 10 % for each
level below. (The figure on the right shows the system with the
maximum electric energy at 200 kW.)
Note: The best set point depends on the system configuration of the electric equipment and the indoor environment in each
building. Choose appropriate set points accordingly.
Note: The amount of electricity that is actually used may exceed the demand value due to such unexpected incidents as controller
problems or broken transmission lines. Mitsubishi will not be responsible for such incidents.
5-2-5 Setting the temperature difference between set point and inlet (All methods)
When the energy-save level is set to 0 (It is always set to
level 0 in an energy-save control method), energy-save
control will not be performed for the indoor units that
show a greater difference between the set temperature and indoor temperature than the value set in the
window on the right.
Make the setting when some type of energy-saving control is effective at energy-save level 0 and the level of
comfort is high on priority list. (Choose between 3 to 9)
