ADDRESS switch
• Change the address switch to prevent mixing of signals from remote
control units when two air conditioners are installed next to each
other. Normally, the address switch is set to A. When switching the
adress, take the steps listed below. Contact your dealer where you made
the purchase if 3 or more air conditioners are to be operated.
1
Break off the address switching tabs on the remote control unit, and
set the address switch to B.
2
Insert batteries into the remote control unit, press the ACL button,
and attach the cover.
3
Open the intake grille of the indoor unit, and set the operation knob
to the DEMO position.
4
Press the ON/OFF operation button on the remote control unit, and
check that a receiving tone (beep) is heard from the indoor unit.
5
Set the operation selector to the ON position, and close the intake
grille.
6
Operate the remote control unit, and check that a receiving tone
(beep) is heard from the indoor unit.
• Normally, the tabs on the remote control unit should not be bent.
A/C SENSOR button
When you press this button (use a small-tipped object such as a
ballpoint pen), the
mark will appear at the display. And the room
temperature is detected by the sensor which is built into the indoor unit
and the air conditioner is controlled accordingly.
NOTE
If the remote control is located near a heat source, such as a space heater
or in direct sunlight, press the A/C SENSOR button to switch to the sensor
on the indoor unit.
NOTE
The remote control unit sends the temperature signal to the air conditioner regularly at five minute
intervals. If the signal from the remote control unit stops for more than ten minutes due to the loss of
the remote control unit or other trouble, the air conditioner will switch to the temperature sensor which
is built into the indoor unit and control the room temperature. In these cases, the temperature around
the remote control unit may differ from the temperature detected at the air conditioner’s position.
