How to set upper and lower limit of temperature sting range
1. Stop the air-conditioner, and press (SET) and (MODE) button at the same time for
3 seconds or more.
The indication changes to"FUNCTION SET "
2. Press button once, and change to the "TEMP RANGE " indication.
3. Press (SET) button, and enter the temperature range setting mode.
4. Confirm that the "Upper limit " is shown on the display.
5. Press (SET)button to fix.
6.
Ԙ Indication: " SET UP" "UPPER 28 㷄 "
ԙ Select the upper limit value 30 㷄 with temperature setting button ."UPPER30 㷄 "
(blinking)
Ԛ
Press (SET) button to fix. "UPPER 30
㷄
" (Displayed for two seconds)
After the fixed upper limit value displayed for two seconds, the indication will returm
to"UPPER LIMIT ".
7. Press button once, "LOWER LIMIT " is selected, press (SET) button to fix.
Ԙ
Indication: " SET UP" "LOWER 20
㷄
"
ԙ Select the lower limit value 18 㷄 with temperature setting button ."LOWER18 㷄 "
(blinking)
Ԛ Press (SET) button to fix. "LOWER 18 㷄 " (Displayed for two seconds)
After the fixed lower limit value displayed for two seconds, the indication will returm
to"LOWER LIMIT "

Regarding the connection of wired remote control, refer to the instruction manual of wired remote control.
Ԙ Switch ON the DIP switch SW2-2 (Factory setting : ON) on the interface PCB.
Caution:Wireless remote control attached to the indoor unit can be used in parallel, after connecting the wired remote control. However,
some of functions other than the basic functions such as RUN/STOP, Temperature Setting, etc. may not work properly and may have
a mismatch between the display and the actual behavior.
ԙ Wiring connection between the interface and the wired remote control.
٨ When using the wireless remote control in parallel with the wired remote control;
Since temperature setting range of wired remote control is different from that of wireless remote control, please adjust the setting range of wired
remote control to be the same setting range of wireless remote control by following procedure. (The set temperature may not be displayed correctly
on the wireless remote control, unless change of temperature setting range is done.)
Changing procedure of temperature setting range is as follows.
Ԛ Clamp the connection cables with cable clamps.
Installation and wiring of wired remote control
A Install the wired remote control with reference to the attached instruction manual of wired remote control.
B 0.3mm
2
x
2-core cable should be used for the wiring of wired remote control.
C
Maximum length of wiring is 600m.
If the length of wiring exceeds 100m, change the size of cable as mentioned below.
100m-200m: 0.5mm
2
x
2-core, 300m or less: 0.75mm 2
x
2-core, 400m or less: 1.25mm 2
x
2-core, 600m or less: 2.0mm 2
x
2-core
However, cable size connecting to the terminal of wired remote control should not exceed 0.5mm
2
. Accordingly if the size of connection
cable exceeds 0.5mm 2 , be sure to downsize it to 0.5mm 2 at the nearest section of the wired remote control and waterproof treatment should
be done at the connecting section in order to avoid contact failure.
D Don't use the multi-core cable to avoid malfunction.
E Keep the wiring of wired remote control away from grounding (Don't touch it to any metal frame of building, etc.).
F Connect the connection cables to the terminal blocks of the wired remote control and the interface securely (no polarity).
Control of multiple units by a single wired remote control
Multiple units (up to 16) can be controlled by a single wired remote control.
In this case, all units connected with a single wired remote control will operate
under the same mode and same setting temperature.
Ԙ
Connect all the interface with 2-core cables of wired remote control line.
ԙ
Set the address of indoor unit for remote control communication from
"0" to "F" with the rotary switch SW1 on the interface PCB.
Ԛ
After turning the power ON, the address of indoor unit can be displayed by
pressing AIR CON button on the wired remote control.
Make sure all indoor units connected are displayed in order by pressing
or button.
Master/Slave setting wired when 2 of wired remote control are used
Maximum two wired remote control can be connected to one indoor unit
(or one group of indoor units)
Ԙ Set the DIP switch SW1 on the wired remote control to "Slave" for the slave
remote control. (Factory setting : Master)
٤ Caution : Remote control sensor is invalid.
