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: 5.0 m, Height difference: 0 m. (Between outdoor unit and indoor unit.)
• Protective function might work when using it outside the operation range.
• *1: Maximum operating current is the total current of the indoor unit and the outdoor unit.
• *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. For details, refer to the setting manual.

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 should be used. Maximum length of cable is 150 m.
• The wire connection should be separate from the power cable line.
¢External input and output PCB
The indoor unit Operation/Stop can be set by using the input connector on the PCB.
•Input select:
Use either one of these types of connectors according to the application. (Both types of connec-
tors cannot be used simultaneously.)
– Dry contact
In case of internal power supply, set the slide switch of SW301 to "NON VOL" side.

8-2. External output
Use an external output cable with appropriate external dimension, depending on the number of ca-
bles to be installed.
¢External input and output PCB
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 25 m.
• Output voltage: High DC 12 V±2 V, Low 0 V.
• Permissible current: 50 mA
• For details, refer to "Combination of external input and output" on page 17.
•When indicator or other components are connected directly:
Example: Rotary SW on External input and output PCB is set to “1”.
