Peak Cut (Energy-Save Control Function) - Mitsubishi AE-200A Instruction Book

7-2-2. Peak Cut (Energy-save control function)

According to the selected Peak Cut method, the AE-200/AE-50/EW-50 obtains the demand level or the electric
energy values to determine the control level, and operates outdoor units and blocks of indoor units below the
specified maximum capacity that corresponds to the control level.
Click [Functions 1] in the menu bar, and then click [Peak Cut] to access the Peak Cut control settings screen. Make
necessary settings, and then click [Save Settings].
Important: The amount of electricity that is actually used may exceed the maximum power demand due to unexpected
problems such as controller malfunctions or broken transmission cables. Mitsubishi Electric will not be
responsible for exceeding the maximum power demand.
Note: After completing the settings, perform a test run and confirm proper connections of equipment before using the Peak Cut
function.
Note: A separate license is required to use the Peak Cut function. Make sure that the required license has properly been registered
on the Registration of Optional Functions screen. (Refer to section 4-5 "License registration for optional functions" for
details.)
Note: Some settings may not be accessible if logged in as a building manager.
Note: Peak Cut control cannot be performed on DIDO controller (PAC-YG66DCA), AHC, Air To Water (PWFY) unit, HWHP (CAHV,
CRHV, QAHV) unit, or chiller unit.
Note: The Peak Cut control of indoor units is performed per block. Be sure to make block settings to use the Peak Cut function.
Note: The Peak Cut control settings between the outdoor and indoor units connected to the AE-200, AE-50, and EW-50, as well as
between the units connected to different AE-50/EW-50 controllers, cannot be made.
