6-2-3-2. Power peak-cut Control (Extended)
Operation
The demand request signal from the outside restricts the maximum capability (or maximum electric power)
of an outdoor unit.
L1: Power peak-cut control indication lamp

SW2: Power peak-cut control OFF switch*1
*1 The inputs of SW1 and SW2 can be either pulse (100 msec or longer) or step signals.
* Be sure to provide a contact for each terminal.
