2-1. Features

• 5-mode timer setup (on, off, weekly, program, and sleep) available.

• Easy operation.

• Easy to change custom code (max. 4 custom code).

• Can be used jointly with wired remote controllers.

 Simple function setting

Setting of the air conditioner selection function is performed by remote controller.

 Built-in timers

Selectable from 4 different timer programs (on, off, program, and sleep).

 Weekly timers

Weekly timer can be easily set by wireless remote controller. On and off can be set up to 4 times in a day, and up to 28 times in a week.

 Program timer

The program timer operates the on and off timer once within a 24-hour period.

 Sleep timer

The sleep timer function automatically corrects the temperature thermostat setting according to the time setting to prevent excessive cooling and heating while sleeping.

Cooling operation/Dry operation

When the sleep timer is set, the set temperature automatically rises 1 °C every hour. The set temperature can rise up to a maximum of 2 °C.

Timer setting

Heating operation

When the sleep timer is set, the set temperature automatically drops 1 °C every 30 minutes. The set temperature can drop to a maximum of 4 °C.

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: 7.5 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.

11-3. Custom code setting for wireless remote controller

To interconnect the air conditioner and the wireless remote controller, assignment of the custom code for the wireless remote controller is required.

NOTE: Air conditioner cannot receive a signal if the air conditioner has not been set for the custom

code.

When 2 or more air conditioners are installed in a room, and the remote controller is operating an air conditioner other than the one you wish to set, change the custom code of the remote controller to operate only the air conditioner you wish to set. (4 selections possible.)

Confirm the setting of the remote controller custom code and the function setting. If these do not match, the remote controller cannot be used to operate for the air conditioner.

1. Press the START/STOP button until only the clock is displayed on the remote controller display.

2. Press the MODE button for at least 5 seconds to display the current custom code. (Initially set to .)

3. Press the TEMP. ( ) ( ) buttons to change the custom code between → → → . Match the code on the display to the air conditioner custom code. (Initially set to .)

WALL MOUNTED

ASTG30, 34KMTA

4. Press the MODE button again to return to the clock display. The custom code will be changed.

Notes:

• If no button is pressed within 30 seconds after the custom code is displayed, the system returns to the original clock indicator. In this case, start again from step 1.

• The air conditioner custom code is set to prior to shipment. To change the custom code, contact your retailer.

• If you do not know the assigned code for the air conditioner, try each of the custom code ( → → → ) until you find the code which operates the air conditioner.

11. External input and output (for AOTG34KMTA)

With using external input and output functions, this product can be operated inter-connectedly with an external device.

Connector Input Output Remarks

CN10 Low noise mode — CN11 Peak cut mode — CN12 — Error status CN13 — Compressor status

See external input/output

settings for details.

11-1. External input

With using external input function, on/off status of “Low noise mode” and “Peak cut mode” can be specified by the external signal.

 Low noise mode

In following condition, the operating noise of the outdoor unit reduces comparing from the one in normal operating condition:

• The air conditioner is set to the “Low noise mode” when closing the contact input of a commercial timer or on/off switch to a connector on the control PCB of the outdoor unit.

NOTE: Product performance may drop depending on some conditions such as the outdoor

temperature.
