By activating server room control using function setting 96, this product maintains a room at constant
ASU30RLE
temperature.
Available operations
When server room control is activated by changing the setting on function setting 96, this product
maintains the room temperature constant by performing 3 types of operations automatically according to the room temperature conditions.
While this function is activated, contents of operation is fixed as follows:
Operation mode Set temperature Airflow mode
COOL 76°F (24°C)* HIGH
*: Set temperature correction (±8°F [4°C]) is possible by switching the setting value on function setting 30. For the setting details, refer to “Room temperature control for indoor unit sensor” in “Con-
tents of function setting” on page 48.
• Alternative operation

Precautions on unit installation
• Do not place any other electrical products or household belongings under the product. Condensation dripping from the product might get them wet, and may cause damage or malfunction to
the property.
• In units installation facing each other, the vertical airflow direction louver on each indoor unit
should be set at a position from 3 to 6.
• Do not connect any wired remote controller.
To perform server room control, mind the followings:
• Additional cable connecting between 2 indoor units needs to be purchased locally.
• DIP switch on the indoor unit main PC board needs to be switched to “3WIRE”.
• Setting of function setting 30 “Room temperature control for indoor unit sensor” on each indoor
unit needs to be same. For contents of the function setting 30, refer to “Room temperature control
for indoor unit sensor” in “Contents of function setting” on page 48.

Before activating server room control, assignment of primary unit and secondary unit is required.
Change the setting of function setting 96 as follows:
1. Turn on the power source of 2 indoor units.
2. Set one of the indoor unit as “Primary unit” (Setting value: 01) by function setting 96. (For
contents of function setting 96, refer to “Server room control” in “Contents of function setting”
on page 48.)
When performing the setting, operate the remote controller close to the signal receiver on the
primary unit as possible so that the signal transmission is firmly received by the primary unit
only.
3. Set the other unit as “Secondary unit” (Setting value: 02) by function setting 96.
When performing the setting, operate the remote controller close to the signal receiver on the
secondary unit as possible so that the signal transmission is firmly received by the secondary
unit only.
4. Turn off the power supply of the 2 indoor units.
Starting units operation
After the setting change on function setting 96 is completed, do as follows:
1. After 30 seconds or more since the power source is turned off, turn of the power source of the
secondary unit.
2. Turn on the power source of the primary unit.
3. Press the MANUAL AUTO button on the primary unit for more than 3 seconds.
You will hear a short beep, and the primary unit starts operation.

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 .)
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.
