l
This mode selects the pattern of the stop
function to be operated by the external
input terminal (CN934).
•Batch stop: The stop of all indoor units
connected to same refrigerant system due
to input signal coming from CN934.
•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 CN934), the air conditioner
does not return to the original operation
until operate indoor unit by the remote
controller.

The capacity limit can be selected when
operating with the “Energy Saving Peak
Cut function.”
The operation selection can be done by
external input terminal(CN933).
The lower the level, the more the effect
of energy saving, but the cooling/heating
performance decreases.
