The capacity limit can be selected by the external input terminal (CN133) when operat-
ing 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.

If the cooling/heating performance becomes insufficient when the low noise mode is set, it is 
possible to set “capacity priority” that automatically cancels the low noise mode (once perfor-
mance is restored, the mode will automatically return to the low noise mode).

*1:  Do not set this for outdoor units with Slave setting.
*2:  When electricity meter No. is set to “000” and “201 to 299”, the pulses input to 

CN135 become ineffective. Available setting number is "001" to "200"

*3:  When the electricity meter pulse setting is set to “0000”, the pulses input to CN135 

become ineffective. Available setting number is "0001" to "9999"

7.3.  Rotary switch setting

The rotary switch (REF AD) sets the refrigerant circuit address of the outdoor unit. Config-
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.

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 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.
