Connection of wired remote control
Regarding the connection of wired remote control, refer to the instruction manual of wired remote control.
①Switch 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.
②Wiring connection between the interface and the wired remote control.
Installation and wiring of wired remote control
Install the wired remote control with reference to the attached instruction manual of wired remote control.
A
0.3mm x 2-core cable should be used for the wiring of wired remote control.
2
B
Maximum length of wiring is 600m.
C
If the length of wiring exceeds 100m, change the size of cable as mentioned below.
x
100m-200m: 0.5mm 2 2-core, 300m or less: 0.75mm
However, cable size connecting to the terminal of wired remote control should not exceed 0.5mm
cable exceeds 0.5mm 2 , be sure to downsize it to 0.5mm
be done at the connecting section in order to avoid contact failure.
Don't use the multi-core cable to avoid malfunction.
D
Keep the wiring of wired remote control away from grounding (Don't touch it to any metal frame of building, etc.).
E
Connect the connection cables to the terminal blocks of the wired remote control and the interface securely (no polarity).
F
③Clamp the connection cables with cable clamps.
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.
①Connect all the interface with 2-core cables of wired remote control line.
②Set the address of indoor unit for remote control communication from
"0" to "F" with the rotary switch SW1 on the interface PCB.
③After turning the power ON, the address of indoor unit can be displayed by
pressing AIR CON No. 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)
①Set the DIP switch SW1 on the wired remote control to "Slave" for the slave
remote control. (Factory setting : Master)
○ Caution : Remote control sensor is invalid.
●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.
How to set upper and lower limit of temperature sting range
1. Stop the air-conditioner, and press
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
