NOTES:
• Specifications are based on the following conditions:
– Cooling: Indoor temperature of 27°CDB/19°CWB, and outdoor temperature of 35°CDB/24°CWB.
– Heating: Indoor temperature of 20°CDB/15°CWB, and outdoor temperature of 7°CDB/6°CWB.
– Pipe length: 5 m, Height difference: 0 m. (Between outdoor unit and indoor unit.)
• Protective function might work when using it outside the operation range.
• *1: Maximum current is maximum value when operated within the operation range.
• *2: Sound pressure level:
– Measured values in manufacturer’s anechoic chamber.
– Because of the surrounding sound environment, the sound levels measured in actual installation conditions might be higher than the specified values here.
• *3: Available on Google Play™ store or on App Store®. Optional WLAN Adapter is also required. For details, refer to the setting manual.

8. External input and output
With using external input and output functions, this product can be operated inter-connectedly with
an external device.
Connector Input Output Remarks
CNA01 Control input — See external input/output
settings for details.
CNB01 — Operation status output
CNB02 — Error status output
8-1. External input
With using external input function, some functions on this product can be controlled from an external
device.
• “Operation/Stop” mode or "Forced stop" mode can be selected with function setting of indoor unit.
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 150 m.
• The wire connection should be separate from the power cable line.
¢Control input (Operation/Stop or Forced stop)
The air conditioner can be remotely operated by means of the following on-site work.
Unit operation is started at the following contents by adding the contact input of a commercially avail-
able on/off switch to a connector on the external control PCB and turning it on.
Unit operation Initial setting after power is on Starting mode other than initial setting
Operation mode Auto changeover Mode at previous operation
Set temperature 24 °C Temperature at previous operation
Airflow mode AUTO Mode at previous operation
Air direction (swing) Standard air direction (swing OFF) Air direction at previous operation
