9.2. Connecting procedures

The remote controller cord may be extended up to 500 m. Since the remote
controller cord supplied with the unit is 10 m-long, use those electric wires or
2
(two-core) cables of 0.3 mm
to 1.25 mm
conductor cables to prevent possible malfunction of the unit.
[Fig. 9.2.1] (P.6)
(1) Connect the remote controller cord to the terminal block for the lower
case.
A To TB5 on the indoor unit
B Terminal block representation
No polarity!
Caution:
Do not use crimp-style terminals for connection to the remote controller ter-
minal block to eliminate contact with the boards and resultant trouble.
(2) Set the dip switch No.1 shown below when using two remote controller's
for the same group.
[Fig. 9.2.2] (P.6) Dip switches
Setting the dip switches
The dip switches are at the bottom of the remote controller. Remote controller
Main/Sub and other function settings are performed using these switches. Ordi-
narily, only change the Main/Sub setting of SW1. (The factory settings are all "ON".)

9.3. Fitting the upper case

[Fig. 9.3.1] (P.6)
(1) Put the upper latches (at two locations) first then fit the upper case into
the lower case as illustrated.
(2) To remove the upper case, put a slotted screwdriver tip in the latches as
shown in the diagram then move the screwdriver in the direction of ar-
row.
Caution:
Do not move the screwdriver while inserting the tip far into the latches to
prevent broken latches.
Be sure to put the screwdriver tip securely in the latches until a snap
sounds. Loosely inserted screwdriver may fall down.
Note:
The operating section is covered with a protective sheet. Before using the
unit, remember to remove the protective sheet.

Changing the power voltage setting
Be sure to change the power voltage setting when operating the unit in an area
where the power source is 220 V or 230 V.
(The power voltage setting is set to 240 V at the factory. Units that are used in areas
where the power source is 240 V do not require power voltage setting changes.)

1 Go to the function setting mode
Switch OFF the remote controller.
Press the A FILTER and B TEST RUN buttons simultaneously and hold them
for at least 2 seconds. FUNCTION will start to flash. The refrigerant address
display will start to flash momentarily.
2 Setting the refrigerant address
Use the C
(TIMER SET) button to set the refrigerant address ⁄
to 00. Press
to increase the value or
00 is the typical setting. When operating in a group configuration, use the
correlating refrigerant address (see the technical manual for details on set-
ting the refrigerant address for a group). The refrigerant addresses must be
set in order when performing the following operation.
*
If the unit stops two seconds after the FUNCTION display starts to flash or
[88] starts to flash in the room temperature display, a transmission problem
may have occurred. Check to see if there is some source of transmission
interference (noise) nearby.
If you make a mistake during any point of this procedure, you can quit the
function setting mode by pressing 8 once and then return to step 1.
3 Setting the unit number
Press D (CLOCK ON OFF) and [--] will start to flash in the unit number ⁄
display.
Use the C
(TIMER SET) button to set the unit number to 00. Press
to increase the value or
Unit number 00 = the function setting selection for the entire refrigerant system
4 Setting the refrigerant address/unit number
Press the E MODE button to designate the refrigerant address/unit number. [-

1
*
If [88] appears in the room temperature section, the selected refrigerant
address does not exist in the system. Also, if [F] appears in the unit number
display section, the selected unit number does not exist. Enter the correct
refrigerant address and unit number at steps 2 and 3.
Fan draft operation will start when settings are confirmed using the E MODE
button. You can also use this operation to find out what functions are as-
signed to which unit numbers and the locations of those indoor units. Note
that the fan draft operation will start for all of the indoor units that have been
assigned refrigerant addresses when 00 or AL is the assigned unit number.
*
If an indoor unit other than those designated with refrigerant addresses
emits a fan draft when a different refrigerant grouping is being used, the set
refrigerant addresses have probably overlapped. Reassign the refrigerant
addresses at the DIP switch of the outdoor unit.
Example) When the refrigerant address is set to 00 and the unit number is 02.

when the flashing settings stay lit.
*
If [--] appears in the room temperature display as the mode/setting number, or
if a flashing [88] display appears, a transmission problem may have occurred.
Check to see if there is some source of transmission interference (noise) nearby.

Press the FILTER A and TEST RUN B buttons simultaneously for at least two
seconds. The function selection screen will disappear momentarily and the air
conditioner OFF display will appear.
