Rotary Switch Setting; Push Button Setting - Fujitsu AirStage AJY040LELAH Installation Manual

7.3. Rotary switch setting

The rotary switch (REF AD) sets the refrigerant circuit address of the outdoor unit. Confi g-
ure the settings only on the master unit of a refrigerant system.
If multiple refrigerant systems are connected, set the rotary switch (REF AD) as shown in
the table below.

Switching between
Batch stop

emergency stop *1
This mode selects the pattern of the stop function to be operated by the external input
terminal (CN134).
20
• 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 emer-
gency 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.

Energy saving
level setting *1
30
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 perfor-
mance will also drop.

Capacity prior-
ity setting (in low
noise mode) *1

If the cooling/heating performance becomes insuffi cient when the low noise mode is set, it is pos-
sible to set "capacity priority" that automatically cancels the low noise mode (once performance is
restored, the mode will automatically return to the low noise mode).
