How To Install
1.
Chose a place in which to install the remote controller (switch box).
Be sure to observe the following steps:
(1) Temperature sensors are provided with both the remote controller and the indoor units. When using the
remote controller temperature sensor, the master remote controller detects the room temperature. In-
stall the master remote controller in a place where the average room temperature can be detected and
which is not affected by any heat source from direct sunlight or air blown from air conditioning units.
(For how to set the master and subordinate remote controller, see step 6 in section 4 How To Install .
For how to set the temperature sensor, refer to the CITY MULTI indoor unit installation manual.)
(2) When installing on either the switch box or the wall, allow extra space around the remote controller as
shown in the figure at the right.
(When using the remote controller in combination with a Program timer, refer to the Program timer
installation manual.)
NOTE: Make sure that there is no wiring or wire near the remote controller sensor. If there is, the remote controller cannot detect the exact room
temperature.
(3) Parts which must be supplied on site.
• Switch box for two units
• Thin-copper wiring pipe
• Lock nut and bushing

CAUTION Do not tighten the screws too tight. Doing so may deform or crack the lower cover.
NOTE: - Chose a flat plane for installation.
- Fasten the switch box at more than two places when installing directly on the wall.
- When reinstalling on the wall, fasten securely using anchors.
5.
Connect the remote control cord to the remote controller terminal block.
CAUTION
Do not use crimp terminals to connect to the remote controller terminal block. To do so may cause the terminals to touch the
board and cause trouble at the remote controller. If the terminals touch the cover, the cover may be damaged.
6.
Set the remote controller address using the rotary switches.
7.
Wiring hole for installing directly on the wall (or open wiring)
• Cut off the shaded area from the upper cover using a knife, nippers, etc.
• Take out the remote control cord connected to the terminal block via this portion.
8.
Install the cover to the remote controller.
First, hook the cover to the two upper claws and then fit it to the remote controller.
CAUTION Press the cover until it snaps shut. If not, it may fall off.
NOTE: A protection sheet is stuck to the operation section. Peel off this protection sheet before use.

How To Connect Optional Parts
•
When connecting a Program timer, connect a 5-core cable to the connector on the remote controller. (A
5-core cable is supplied with the Program timer.)
•
To route the cable, cut off the thin-wall portion.
•
For wiring path convenience, install the Program timer to the left-hand side of the remote controller.
When expansion is expected, take into consideration remote controller space at the left-hand side.
For the operation method details, refer to the Program timer installation manual.
Use standard wires in compliance with the current capacity.
A failure to this may result in an electric leakage, heating or fire.
Do not touch any PCB (Printed Circuit Board) with your hands or with
tools. Do not allow dust to collect on the PCB.
Doing so may cause fire or an electric shock.
Do not remove the insulation sheet on the PCB.
Doing so may cause an electric shock.
Do not touch any control button with your wet hands.
Doing so may cause an electric shock or a malfunction.
Do not press any control button using a sharp object.
Doing so may cause an electric shock or a malfunction.
Never contact the power supply with the control wiring terminals.
Doing so will certainly cause the controller to catch fire.
When installing the remote controller in a hospital or communication
facility, take ample countermeasures against noise.
Inverters, emergency power supply generators, high-frequency medical equip-
ment, and wireless communication equipment can cause the remote control-
ler to malfunction or to fail. Radiation from the remote controller may effect
communication equipment and prevent medial operations on the human body
or interfere with image transmission and cause noise.
Ensure that installation work is done correctly following this installa-
tion manual.
Any deficiency caused by installation may result in an electric shock or fire.
All electrical work must be performed by a licensed technician, accord-
ing to local regulations and the instructions given in this manual.
Any lack of electric circuit or any deficiency caused by installation may result
in an electric shock or fire.

Remote controller functions selection
In the remote controller function selection mode, three functions can be selected and changed. Select and change these functions, as required.
For the operating instructions refer to “(6) How to select the remote controller functions” of 3 How to Operate in Instruction Book.
(A) Operation mode display selection mode (“AUTO” mode heating/cooling display selection)
When the AUTO mode was selected with the remote controller, the indoor unit is judged from the room temperature and heating or cooling is
performed automatically. In this case, “AUTO” “COOLING” or “AUTO” “HEATING” is displayed at the remote controller. However, only “AUTO” without
“COOLING” or “HEATING” can also be displayed.
(B) Room temperature display selection mode (Room temperature display/no display selection)
Normally, the intake air temperature is displayed at the remote controller. However, no display can also be selected.
(C) Set temperature range limit mode
Ordinarily, the set temperature can be freely set over the 19
°
C to 30
°
C range for cooling and dry and the 17
°
C to 28
°
C range for heating. However,
for cooling and dry, the lower limit temperature and for heating, the upper limit temperature can be limited to a preset temperature. If the set
temperature range is made higher for cooling and dry and is set lower for heating by this method, excessive cooling and heating can be prevented
and energy can be saved.
CAUTION
When the normal set temperature adjustment range was changed using a remote controller connected to a simultaneous cooling/
heating air condition with an AUTO mode, the AUTO mode cannot be selected with the [Mode selection] button.
