11000 – 1999
If the wired remote controller and system controller are not used together,
the details of the check codes in the error history can be checked using the
LED display of the outdoor PC board.
To check the error history of the outdoor unit, refer to the outdoor unit
service handbook.
22000 – 2999
33000 – 3999
44000 – 4999
55000 – 5999

80 – 999
Notes:
1. If the beeper does not sound and the OPERATION INDICATOR lamp remains off after the signal was received when the self-check starts,
there is no error history.
2. If the beeper sounds 3 times continuously “beep, beep, beep (0.4 + 0.4 + 0.4 seconds)” after the signal was received when the self-check
starts, the specified refrigerant address (M-NET address) is incorrect.

7.3. Unit function selection
This setting method is for Mr. Slim. For CITY MULTI models, set the DIP switches on the indoor PC
board and outdoor PC board.
To set the DIP switches, refer to the technical materials for the CITY MULTI models.
Set the functions as necessary using the remote controller. The functions for each unit can be set only
from the remote controller.
Select the functions from table 1 that must be set.
Only the refrigerant systems that are connected to indoor units equipped with wireless remote controller
receivers can be set from the wireless remote controller operation unit. The refrigerant address cannot be
speciedusingthewirelessremotecontrolleroperationunit.
Table 1 Function selection settings (For details about the factory settings and modes of each
indoor unit, refer to the indoor unit installation manual.)
Note: The items in the following table are representative examples. Because the settings for each
mode may vary depending on the model, refer to the indoor unit installation manual for details.

1. Press the button 1to stop the air conditioner.
* If the weekly timer is enabled ( A is on), press
the button 2to disable it ( A is off).
2. Press the button 3for 5 seconds.
• Bcomes on and the unit enters the self-check
mode.
3. Press the button 4to set the displayed number D
to "50".
• While pointing the wireless remote controller toward
the receiver, press the button 5. (The unit
number blinks.)
4. Press the button 4to set the unit number of the
indoor unit.
• While pointing the wireless remote controller toward
the receiver, press the button 5. (The mode
number blinks.)
* When the unit number is transmitted, the selected
indoor unit starts operating in the fan mode.
You can use this step to confirm which indoor unit
corresponds to the unit number you selected to
change the functions.
However, if you set the unit number to "00" or "AL",
all of the indoor units in the same refrigerant system
will start operating in the fan mode.
* If you transmit a unit number that cannot be
selected, the beeper sounds 3 times continuously
“beep, beep, beep (0.4 + 0.4 + 0.4 sec.)”.
If this occurs, press the button 6, and then
set the unit number again while the unit number
display is blinking.
* If the signal was not received correctly, the beeper
will not sound or it will beep twice.
If this occurs, press the button 6, and then
set the unit number again while the unit number
display is blinking.
Function selection procedure (Fig. 7-3, 7-4)
First, it is important to understand the procedure for the function selection. The following procedure explains how to set
"LOSSNAY connectivity" in table 1 to "Supported (indoor unit is not equipped with outdoor-air intake)" as an example.
For the actual operations, refer to the following procedure.

5. Press the button 4to set the mode number.
• While pointing the wireless remote controller toward
the receiver, press the button 5. (The setting
number blinks.)
At this time, the beeper sound and OPERATION IN-
DICATOR lamp blinking pattern indicate the current
setting number for the selected mode number.
Current setting value = 1: Beep (1 sec.) × 1 time
= 2: Beep (1 sec.) × 2 times
= 3: Beep (1 sec.) × 3 times
* If you enter a mode that cannot be set, the beeper
sounds 3 times continuously “beep, beep, beep (0.4
+ 0.4 + 0.4 sec.)”.
If this occurs, press the button 6, and then
set the mode number again while the mode number
display is blinking.
* If the signal was not received correctly, the beeper
will not sound or it will beep twice.
If this occurs, press the button 6, and then
set the mode number again while the mode number
display is blinking.
6. Press the button 4to select the setting number.
• While pointing the wireless remote controller toward
the receiver, press the button 5. (The mode
number blinks.)
At this time, the beeper sound and OPERATION IN-
DICATOR lamp blinking pattern indicate the setting
number for the selected mode number.
Current setting value = 1: Beep (1 sec.) × 1 time
= 2: Beep (1 sec.) × 2 times
= 3: Beep (1 sec.) × 3 times
* If you enter a number that cannot be set, the origi-
nally set number will be used.
* If the signal was not received correctly, the beeper
will not sound or it will beep twice.
If this occurs, repeat the procedure from step 5.
7. To set another mode without changing the unit number
of the indoor unit, repeat steps 5 and 6.
8. To change the unit number of the indoor unit and
perform the function selection, repeat steps 4–6.
9. Press the button 1to complete the function
selection.
Note:
● After the function selection is complete, do not
operate the wireless remote controller for 30
seconds.
● Whenever the function selection is used to
change the indoor unit functions after installa-
tion, be sure to record all of the settings with a
“○” or other mark in the “Initial setting” column
of the table.
