[3.2 Electrical Wiring for Multiple Units]
CAUTION
A. Use a 0.3 to 0.75mm2 cable for connecting. The maximum total cable length is up 30m. If the total cable length
exceeds 30m, use a twist pair cable with shield tube(1P - 0.75mm2 or more). In that case, the maximum total cable
length is up to 500m. If using in combination with the control timer, the allowable total cable length is up to 100m.
The use of a cable other than that specied above can cause of malfunction due to the effects of noise.
B. Keep a distance more than 30cm between the transmission line (remote control cable and transmission wires) and
power source of the indoor units.
If not, the air-conditioner may not operate properly or malfunction may occur due to effect of power source noise.
C. In case of simultaneously controlling multiple indoor units, set the refrigerant cycle numbers and addresses of the
indoor units without overlapping.
D. Refer to the Technical Catalog provided with each indoor unit when performing electrical wiring work between the
controller and indoor units for setting the refrigerant cycle number and the indoor unit address.
E. No gap shall exist between the remote control cable and hole of the controller case. If there is a gap, cover the gap
with vinyl tape.
If not, malfunction may occur due to entrance of water droplets or insects.
F. In case of operating with two controllers (Main and Sub), set the main and sub controllers by selecting the appropriate
function with the controllers according to the section 5. After setting it, turn off the power supply of all the indoor unit
connected to the controllers.
4. Checking Procedures
1) Turn ON the power supply for all the indoor units.
NOTE:
Although a portion of the LCD (liquid crystal display) of the controller may light immediately after the power is turned on,
this is not a malfunction.
2) For the models with the auto-address function, wait for 3 minutes approximately. The addressing is automatically
performed. (There is a case that 5 minutes is required according to the setting condition.)
3) Set the “TEST RUN” mode by pressing the “MODE” and “CHECK” switch simultaneously for more than 3 seconds.
NOTES:
A. “TEST RUN” is displayed on the LCD.
B. The total number of the indoor units connected
is indicated on the LCD.
C. In case that the indicated number is not correct, the auto-address function is not performed correctly due to incorrect
wiring, the electric noise or etc. Turn OFF the power supply and correct the wiring after checking the following
points;
(Do not repeat turning ON and OFF within 10 seconds.)
1. Power Supply for Indoor Unit is Not Turned ON or Incorrect Wiring.
2. Incorrect Connection of Connecting Cable between Indoor Units or Incorrect Connection of Remote Control Cable
3. Incorrect Setting of Rotary Switch and Dip Switch (The setting is overlapped.) on the Indoor Units PCB
D. Check to ensure that the “TEST RUN” mode is not set.
unit
Example when 5 indoor units are connected.

4) Canceling “TEST RUN” Mode
1. When the unit is not operating, press the RESET switch.
2. When the unit is operating, press the RUN/STOP switch.
ATTENTION:
When “00” is indicated, the auto-address function may be performing.
Cancel the “TEST RUN” mode and set it again.
