Set the outdoor unit's refrigerant address.
Press the [
CLOCK] buttons (
and
) (

the previous page) to select the desired refrigerant address. The refrigerant
address changes from "00" to "15".
(This operation is not possible for single refrigerant systems.)
If the unit stops after
FUNCTION
SELECTION
blinked for 2 seconds or "88" blinks in the room temperature display area for 2 seconds, a transmission error may have occurred.
Check to see if there are any sources of noise or interference near the transmission path.
Note: If you have made operational mistakes during this procedure, exit function selection (see step
0
), and then restart from step
2
.

Set the indoor unit number.
Press the
ON/OFF
button (
D
in the picture in the previous page) so that
"- -" blinks in the unit number display area.
Press the [
CLOCK] buttons (
and
) (
C
in the picture in the
previous page) to select the unit number of the indoor unit for which you want to perform
function selection. The unit number changes to "00", "01", "02","03",04" and "AL" each
time a button is pressed.
To set modes 01 to 06 or 15 to 22 select unit number "00".
To set modes 07 to 14 or 23 to 28 carry out as follows:
• To set each indoor unit individually, select " 01" to "04".
• To set all the indoor units collectively, select " AL".

Confirm the refrigerant address and unit number.
Press the button (
E
in the picture in the previous page) to confirm
MODE
the refrigerant address and unit number.
After a while, "- - " will start to blink in the mode number display area.
When the refrigerant address and unit number are confirmed by pressing the
MODE
button (
E
in the picture in the previous page), the corresponding
indoor unit will start fan operation. This helps you find the location of the indoor
unit for which you want to perform function selection. However, if "00" or "AL"
is selected as the unit number, all the indoor units corresponding to the specified
refrigerant address will start fan operation.
"88" will blink in the room temperature display area if the selected refrigerant
address does not exist in the system.
Furthermore, if "F" appears and blinks in the unit number display area and the
refrigerant address display area also blinks, there are no units that corre-
spond to the selected unit number. In this case, the refrigerant address and unit
number may be incorrect, so repeat steps
2
and
3
to set the correct ones.
When grouping different refrigerant systems, if an indoor unit other than the
one to which the refrigerant address has been set performs fan operation,
there may be another refrigerant address that is the same as the specified one.
In this case, check the DIP switch of the outdoor unit to see whether such a
refrigerant address exists.
6
Select the mode number.
Press the [
TEMP] buttons (
and
) (
F

Press the
MODE
button (
E
in the picture in the previous page).
The mode number and setting number will start to blink and registration starts.
The mode number and setting number will stop blinking and remain lit,
indicating the end of registration.
If " - - - "
is displayed for both the mode number and setting number and "
" blinks in the room temperature display area, a transmission error may have occurred.
Check to see if there are any sources of noise or interference near the transmission path.
