The indication when power source is supplied
When power source is turned on, the following is displayed on the remote control until the
communication between the remote control and indoor unit settled.
Master remote control : " "
Slave remote control : " "
At the same time, a mark or a number will be displayed for two seconds first.
This is the software's administration number of the remote control, not an error cord.
The range of temperature setting
When shipped, the range of set temperature differs depending on the operation mode as below.
Heating : 16
-
30°C (55
-
86°F)
Except heating (cooling, fan, dry, automatic) : 18
-
30°C (62
-
86°F)
Upper limit and lower limit of set temperature can be changed with remote control.
Upper limit setting: valid during heating operation. Possible to set in the range of 20 to 30°C (68
to
86°F).
Lower limit setting: valid except heating (automatic, cooling, fan, dry) Possible to set in the range of 18 to 26°C (62
to
79°F).
When you set upper and lower limit by this function, control as below.
1. When TEMP RANGE SET, remote control function of function setting mode is "INDN CHANGE" (factory setting),
During heating, you cannot set the value exceeding the upper limit.
During operation mode except heating, you cannot set the value below the lower limit.
2. When TEMP RANGE SET, remote control function of function setting mode is "NO INDN CHANGE"
During heating, even if the value exceeding the upper limit is set, upper limit value will be sent to the indoor unit.
But, the indication is the same as the temperature set.
During except heating, even if the value lower than the lower limit is set, lower limit value will be sent to the indoor unit.
But, the indication is the same as the temperature set.
How to set upper and lower limit value
1. Stop the air-conditioner, and press (SET) and (MODE) button at the same time for over three
seconds .
The indication changes to "FUNCTION SET ".
2. Press button once, and change to the "TEMP RANGE " indication.

When remote control cannot communicate with the indoor unit for half an hour, the below indication will
appear.
Check wiring of the indoor unit and the outdoor unit etc.
Read together with indoor unit's installation manual.
Accessories Remote control, wood screw (ø3.5s16) 2 pieces
Prepare on site Remote control cord (2 cores) the insulation thickness in 1mm or more.
[In case of embedding cord] Erectrical box, M4 screw (2 pieces)
[In case of exposing cord] Cord clamp (if needed)
Screw
Installation procedure
Open the cover of remote control, and remove the screw under the
buttons without fail.
Remove the upper case of remote control.
Insert a flat-blade screwdriver into the dented part of the upper part
of the remote control, and wrench slightly.
[In case of embedding cord]
Embed the erectrical box and remote control cord beforehand.
Prepare two M4 screws (recommended length is 12-16mm) on site, and install the lower case to erectrical box.
Choose either of the following two positions in fixing it with screws.
Connect the remote control cord to the terminal block.
Connect the terminal of remote control (X,Y) with the terminal of
indoor unit (X,Y). (X and Y are no polarity)
Install the upper case as before so as not to catch up the remote control cord,
and tighten with the screws.
[In case of exposing cord]
You can pull out the remote control cord from left upper part or center upper part.
Cut off the upper thin part of remote control lower case with a nipper or knife,
and grind burrs with a file etc.
Install the lower case to the flat wall with attached two wooden screws.
Connect the remote control cord to the
terminal block.
Connect the terminal of remote control (X,Y)
with the terminal of indoor unit (X,Y).
(X and Y are no polarity)
Wiring route is as shown in the right diagram
depending on the pulling out direction.
The wiring inside the remote control case should be within 0.3mm
2
(recommended) to 0.5mm
2
.
The sheath should be peeled off inside the remote control case.
The peeling-off length of each wire is as below.
Pulling out from upper left
Pulling out from upper center
X wiring : 215mm
Y wiring : 195mm
X wiring : 170mm
Y wiring : 190mm
Install the upper case as before so as not to catch up the remote control cord, and tighten with
the screws.
In case of exposing cord, fix the cord on the wall with cord clamp so as not to slack.

WARNING
CAUTION
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 supply is turned off when electric wiring work.
Otherwise, electric shock, malfunction and improper running may occur.
DO NOT install the remote control at the following places in order to avoid malfunction.
DO NOT leave the remote control without the upper case.
(1) Places exposed to direct sunlight
(2) Places near heat devices
(3) High humidity places
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.
(4) Hot surface or cold surface enough to generate condensation
(5) Places exposed to oil mist or steam directly
(6) Uneven surface
Tighten the screws after
