Simple Remote Control Installation Manual

Read together with indoor unit's installation manual.

WARNING

●

Fasten the wiring to the terminal securely and hold the cable securely so as not to apply

unexpected stress on the terminal.

Loose connection or hold will cause abnormal heat generation or fire.

●

Make sure the power source is turned off when electric wiring work.

Otherwise, electric shock, malfunction and improper running may occur.

CAUTION

●

Do not leave the remote control without the upper case.

In case the upper cace needs to be detached, protect the remote control with a packaging box
or bag in order to keep it away from water and dust.

●

Do not install the remote control at the following places in order to avoid malfunction.

(1) Places exposed to direct sunlight

(4) Hot surface or cold surface enough to generate condensation

(2) Places near heat devices

(5) Places exposed to oil mist or steam directly

(3) High humidity places

(6) Uneven surface

Accessories

Remote control, wood screw (

3.5

16) 2 pieces

Prepare on site

Remote control cord (2 cores) (Refer to [2. Installation and wiring of remote control])

[In case of embedding cord] Electrical box, M4 screw (2 pieces)

[In case of exposing cord] Cord clamp (if needed)

Installation procedure

In case of embedding cord

⑴　

Make certain to remove the screw on the bottom
surface of the remote control.

⑵　

Remove the upper case of the remote control.

Insert a flat-blade screwdriver to a concave portion of the bottom
surface of the remote control and slightly twist it, and the case is
removed.

⑶　

Pre-bury the electrical box and remote control cord.

⑷　

Prepare two M4 screws (recommended length: 12 – 16mm), and install the lower case to the electrical box.

Do not use a screw whose screw head is larger than the height of the wall around the screw hole.

⑸　

Connect the remote control cord to the terminal block.

Connect the terminals (X and Y) of the remote control and the terminals (X and Y) of the indoor
unit. (No polarity of X and Y)

⑹　

Mount the upper case for restoring to its former state so as not to crimp the remote control cord,
and secure with the removed screw.

In case of exposing cord

⑴　

Make certain to remove a screw on the bottom surface of the
remote control.

⑵　

Remove the upper case of the remote control.
Insert a flat-blade screwdriver to a concave portion of
the bottom surface of the remote control and slightly
twist it, and the case is removed.

⑶　

The remote control cord can be extracted from the
upper center.
After the thin part in the upper side of the remote
control upper case is scraped with a nipper or knife,
remove burr with a file.

⑷　

The lower case of the remote control is mounted to
a flat wall with two accessory wood screws.

⑸　

Connect the remote control cord to the terminal block.
Connect the terminals (X and Y) of the remote control and
the terminals (X and Y) of the indoor unit. (No polarity of X and
Y)
The wiring route is as shown in the right.

The wiring in the remote control case should be 0.3 mm

(recommended) to 0.5 mm

maximum.
Further, peel off the sheath.
The peeling length of each wiring is as follows:

X wiring : 160mm
Y wiring : 150mm

⑹　

Mount the upper case for restoring to its former state so as not to
crimp the remote control cord, and secure with the removed screw.

⑺　

In the case of exposing installation, secure the remote control cord to the wall surface with a
cord clamp so as not to loosen the remote control cord.

Installation and wiring of remote control

⑴

Wiring of remote control should use 0.3mm

× 2 cores wires or cables. (on-site configuration)

⑵

Maximum prolongation of remote control wiring is 600 m.
If the prolongation is over 100m, change to the size below.
But, the wiring in the remote control case should be 0.3mm

(recommended) to 0.5mm

Change the wire size outside of the case according to wire connecting. Waterproof treatment is
necessary at the wire connecting section. Be careful about contact failure.

⑵　

Set the switch SW1-1 of the slave remote control is “Slave” (ON). The factory default is set as “Master” (OFF).

(Note)

•

The remote control thermistor enabled setting can be set only to the master remote control.

•

Install the master remote control at the position to detect room temperature.

•

The air

conditioner operation follows the last operation of the remote control in case of the

master / slave setting.

Master/ slave setting when more than one remote control are used

⑴　

Up to two remote controls can be connected to one unit (or one group) of indoor unit.

The indication when power source is supplied

⑴　

At the time of turning the power source on, after the light is on for the first 2 seconds, the display

becomes as shown below.

The number displayed on the upper side of LCD in the remote control is the software number,

and this is not an error code.

⑵　

Then, “88.0 °C” blinks on the remote control until the communication between the remote

control and the indoor unit is established.

⑶　

In the case of connecting one remote control with one unit (or one group) of indoor unit, make

certain to set the master remote control (factory default).

If the slave remote control is set, a communication cannot be

established.

⑷　

If a state where the communication between the remote

control and the indoor unit cannot be established continues

about for 30 minutes, “E” is displayed. Confirm the wiring of

the indoor unit and the outdoor unit and master/slave setting of

the remote control.

Confirmation method for return air temperature

Return air temperature can be confirmed by the remote control operation.

⑴

Press AIR CON No. button for over 5 seconds.

“88” blinks on the temperature setting indicator.
(“88” blinks for approximately 2 seconds while data are read.)

　　　　　↓

Then, the return air temperature is displayed.
(Example) return air temperature: “27 °C” (blinking)
(Note) For the return air temperature, in the normal case, the return air temperature of the indoor

unit is displayed; however, in the case that the remote control thermistor is effective,
detected temperature by the remote control thermistor is displayed.

⑵

Press

ON/OFF button.

End.

[In the case that the remote thermistor is ineffective and plural indoor units are connected to one
remote control ]

⑴

Press AIR CON No. button for over 5 seconds.

indoor unit No. indicator: “U 000” (blinking)
(Among the connected indoor units, the lowest
number is displayed.)

⑵

Press TEMP

Dectder the indoor unit No.
(Example) indoor unit No. indicator: “U 000”
“88” blinks on the temperature setting indicator. (blinking for approximately 2 to 10 seconds while
data is read) Then, the return air temperature is displayed. When

AIR CON No.

is pressed, return

to the indoor unit selection display (example, “U 000”).
