Type Wall mounted Inverter heat pump

Model name ASUH09LMAS ASUH12LMAS

NOTES:

• Specifications are based on the following conditions:

– Cooling: Indoor temperature of 80 °F (26.67 °CDB) /67 °FWB (19.44 °CWB), and outdoor temperature of 95 °FDB (35 °CDB) / 75 °FWB (23.9 °CWB).

– Heating: Indoor temperature of 70 °FDB (21.11 °CDB) /60 °FWB (15.56 °CWB), and outdoor temperature of 47 °FDB (8.33 °CDB) /43 °FWB (6.11 °CWB).

– *1: Heating (17 °F): Indoor temperature of 70 °FDB (21.11 °CDB) /60 °FWB (15.56 °CWB), and outdoor temperature of 17 °FDB (-8.33 °CDB) /15 °FWB (-9.44 °CWB).

– Pipe length: 25 ft (7.5 m), Height difference: 0 ft (0 m). (Between outdoor unit and indoor unit.)

• Protective function might work when using it outside the operation range.

• *2: Maximum current is maximum value when operated within the operation range.

• *3: 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.

• *4: Available on Google Play^™ store or on App Store^®. Optional WLAN adapter is also required. 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 (22AWG) should be used. Maximum length of cable is 492 ft (150 m).

• The wire connection should be separate from the power cable line.
