• 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 conditioner
does not return to the original operation until the indoor unit is turned on by the
remote controller.

Prohibited
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.
