This setting is available only for Mr. Slim model. CITY MULTI model can be set by dip switch of indoor/outdoor
control circuit board. Refer to technical data of CITY MULTI model to set dip switch.
Each function can be set according to necessity using the remote controller.
The setting of function for each unit can only be done by the remote controller.
Select function available from the Table3. Function selection using wireless remote controller
is available only for refrigerant system with wireless function. Refrigerant address cannot
be specified by the wireless remote controller.
The article below describes how to set “LOSSNAY connectivity” into “supported
(indoor unit is not equipped with outdoor-air intake)” in Table 3 as an example.
1Go to the function select mode
Press the button Ftwice continuously.
(Start this operation from the status of remote controller display turned off.)
CHECK is lighted and “00” blinks.
Press the temp button C once to set “50”. Direct the wireless remote
controller toward the receiver of the indoor unit and press the button A.
2Setting the unit number
Press the temp button Cand D to set the unit number “00”. Direct
the wireless remote controller toward the receiver of the indoor unit and
press the button B.
3Selecting a mode
Enter “03” to change the LOSSNAY connectivity setting using the Cand
Dbuttons. Direct the wireless remote controller toward the receiver
of the indoor unit and press the button A.
Current setting number: 1=1 beep (1 second)
2=2 beeps (1 second each)
3=3 beeps (1 second each)
W If a mode number that can not be recognized by the unit is entered,
3 beeps (3 beeps of 0.4 seconds duration) will be heard.
Reenter the mode number selecting.
W If the signal was not received by the sensor or an error occurred during
transmission, you will not hear a beep or a “double beep” may be heard.
Press the button again.
4Selecting the setting number
Use the Cand D buttons to change the LOSSNAY connectivity setting
to “02”. Direct the wireless remote controller toward the sensor of the indoor
unit and press the button A.
→ At this time, current setting number for selected mode number will be output
by the interrupted buzzer sounds and the blinks of operation indicator.
Output : setting number = 1 → beep beep (0.4 second + 0.4 second) ×1
2 → beep beep (0.4 second + 0.4 second) ×2
3 → beep beep (0.4 second + 0.4 second) ×3
W If a setting number that can not be recognized by the unit is entered, 3 beeps
(3 beeps of 0.4 seconds duration) will be heard (unit will beep only).
Reenter the setting number selecting.
W If the signal was not received by the sensor or an error occurred during
transmission, you will not hear a beep or a “double beep” may be heard.
Press the button again.
W If the number that can not be set is input, the former setting number will be set.
5To select multiple functions continuously
Repeat steps 3and 4to change multiple function settings continuously.
6Complete function selection
Direct the wireless remote controller toward the sensor of the indoor unit
and press the button E.

Things to remember when entering function selections:
The basic procedure for entering function selections is the same as described for switching between LOSSNAY connectivity.
However, there are some differences at step 2for selecting the unit number, step 3for selecting the mode number and
step 4for selecting the setting number.
The following Tables 4 and 5 list the various function settings, mode numbers and setting numbers.
Table 4 details the function of the entire refrigerant system while Table 5 shows the function that can be set for the indoor unit.
