The start-up timing of outdoor unit (compressor) can be set up so that it can
delay several seconds.
This feature is useful when multiple number of outdoor units are installed and
turned on at the same time to limit the starting current.

This mode selects the pattern of the stop function to be operated by the external
input terminal (CN134).
• Batch stop: The stop of all indoor units connected to same refrigerant system
due to input signal coming from CN134.
• Emergency stop: When emergency stop is actuated, the indoor unit does not
accept the operation command from the remote controller. On the other hand,
when the emergency stop is released (no input from CN134), the air condi-
tioner does not return to the original operation until the indoor unit is turned on
by the remote controller.

When installing a duct to the blow-off outlet of an outdoor unit, set the high static
pressure mode according to the static pressure of the duct to be installed.
Furthermore, use this setting if the air blow of an outdoor unit is poor, such as when
installed in a place with a low ceiling.

The capacity limit can be selected by the external input terminal (CN133) when
operating with the “Energy Saving Peak Cut function”.
The lower the level, the more the effect of energy saving, but the cooling/heating
performance will also drop.
