5-2-3 When PI Controller Method is used (1) Select the PI controller to which the watt-hour mete r used for peak cut control is connected.
Note: Only the watt-hour meters that have been registered on the Measurement screen can be selected.
(2) Determine the range of electricity use for each control le vel ( dem and leve l), ta k ing into cons idera tion s uch
factors as delayed control of the air conditioner. Ente r the value that is 10 to 15% belo w 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 figur e on the right shows the s ystem with the max imum
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.
(3) 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 gre ater differenc e between the
set temperature and indoor temperature than the value s et in the window on the right.
Make the setting when some type of energy-saving control is ef f ec tive at e ner g y-save level 0 and the level
of comfort is high on priority list. (Choose between 3 to 9)
(1) Enter the IP address of the G-50 to which the PI controller (with t he connection to the watt-hour meter used
for peak cut control) is connected.
Note: As the control level of G-50 to which the watt-hour meter is c onnected is monitored every minute, the control level changes
after a delay of approx. one minute. Take this delay into consideration, and set the control level without exceeding the
range of peak cut electricity.
Note: Only up to three G-50 can be connected to the G-50 to which the watt-hour meter is connected. When five or more
AG-150A are used in a system, use electric amount count PLC method mentioned in 5-2-2.
(2) 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 gre ater differenc e between the
set temperature and indoor temperature than the value s et in the window on the right.
Make the setting when some type of energy-saving control is ef f ec tive at e ner g y-save level 0 and the level
of comfort is high on priority list. (Choose between 3 to 9)
