Connection of wired remote controller
Interface kit(1)
Interface kit(2)
Interface kit(16)
DIP suitch
(SW2-2)
Rotary
switch
Remote controller line (no polarity)
Remote controller line
(no polarity)
Regarding the connection of wired remote controller, refer to the instruction manual of wired remote controller.
①
Switch ON the DIP switch SW2-2 (Factory setting : ON) on the interface PCB.
Caution:Wireless remote controller attached to the indoor unit can be used in parallel, after connecting the wired remote controller. 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.
②
Wiring connection between the interface and the wired remote controller.
●
When using the wireless remote controller in parallel with the wired remote controller;
Temperature setting range should be changed with the wired remote controller (The set temperature may not be displayed correctly on the
wireless remote controller, unless change of temperature setting range is done.)
Changing procedure of temperature setting range is as follows.
③
Clamp the connection cables with cable clamps.
Installation and wiring of wired remote controller
A
Install the wired remote controller with reference to the attached instruction manual of wired remote controller.
B
0.3mm
2
x 2-core cable should be used for the wiring of wired remote controller.
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 controller 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 controller 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 controller 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 controller and the interface securely (no polarity).
Control of multiple units by a single wired remote controller
Multiple units (up to 16) can be controlled by a single wired remote controller.
In this case, all units connected with a single wired remote controller will operate
under the same mode and same setting temperature.
①
Connect all the interface with 2-core cables of wired remote controller line.
②
Set the address of indoor unit for remote controller communication from
"0" to "F" with the rotary switch SW1 on the interface PCB.
③
After turning the power ON, the address of indoor unit can be displayed by
pressing AIR CON button on the wired remote controller.
Make sure all indoor units connected are displayed in order by pressing
or button.
Master/Slave setting wired when 2 of wired remote controller are used
Maximum two wired remote controller can be connected to one indoor unit
(or one group of indoor units)
①
Set the DIP switch SW1 on the wired remote controller to "Slave" for the slave
remote controller. (Factory setting : Master)
○
Caution : Remote controller sensor is invalid.
