Connection Of Wired Remote Controller; Installation And Wiring Of Wired Remote Controller; Control Of Multiple Units By A Single Wired Remote Controller; How To Set Upper And Lower Limit Of Temperature Sting Range - Mitsubishi Electric DXK09ZJ-S Technical Manual

Connection of wired remote controller

Regarding the connection of wired remote controller, refer to the instruction manual of wired remote controller.
①Switch 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.
②Wiring connection between the interface and the wired remote controller.

Installation and wiring of wired remote controller

Install the wired remote controller with reference to the attached instruction manual of wired remote controller.
A
0.3mm x 2-core cable should be used for the wiring of wired remote controller.

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 controller should not exceed 0.5mm
2
cable exceeds 0.5mm , 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 controller 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 controller and the interface securely (no polarity).
F
③Clamp the connection cables with cable clamps.

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.
①Connect all the interface with 2-core cables of wired remote controller line.
②Set the address of indoor unit for remote controller 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 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)
①Set 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.
●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.

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
5. Press (SET)button to fix.
6. ①Indication: " SET UP" "UPPER 28℃
②Select the upper limit value 30℃ with temperature setting button
(blinking)
(SET) button to fix. "UPPER 30℃" (Displayed for two seconds)
③Press
After the fixed upper limit value displayed for two seconds, the indication will returm
to"UPPER LIMIT ".
7. Press button once, "LOWER LIMIT
①Indication: " SET UP"
②Select the lower limit value 18℃ with temperature setting button
(blinking)
(SET) button to fix. "LOWER 18℃" (Displayed for two seconds)
③Press
After the fixed lower limit value displayed for two seconds, the indication will returm
to"LOWER LIMIT "
8. Press ON/OFF button to finish.
