WIRING EXAMPLE AND HOW TO SET THE
REMOTE CONTROLLER
How to connect wiring (see figure 13)
•
Power supply wiring
Remove the switch box lid (1) and connect the wires to the
power supply terminal board inside. While doing this, pull the
wires inside through the rubber bush A and clamp the wires
along with other wires using clamp A, untightening the clip of
clamp A by pressing. After the connection, tighten clamp A as
before.
•
Unit wiring and remote controller wiring
Remove the switch box lid (2) and pull the wires inside
through the rubber bush B and connect to the terminal board
for unit transmission wiring.
•
After connection
Attach the small sealing (supplied with the unit) around the
cables to prevent infiltrating of water from the outside into the
unit. If two or more cables are used, divide the small sealing
into the required number of pieces and wrap them around all
the cables.

PRECAUTIONS
1 Observe the notes mentioned below when wiring to the power
supply terminal board.
•
Do not connect wires of different gauge to the same power
supply terminal. (Looseness in the connection may cause
overheating.)
•
When connecting wires of the same gauge, connect them
according to the figure.
Use the specified electric wire. Connect the wire securely
to the terminal. Lock the wire down without applying
excessive force to the terminal. (Tightening torque:
131Ncm
±
10%).
2 Keep total current of crossover wiring between indoor units
less than 12A. Branch the line outside the terminal board of
the unit in accordance with electrical equipment standards,
when using two power wiring of a gauge greater than 2mm
2
(Ø1.6).
The branch must be sheathed in order to provide an equal or
greater degree of insulation as power supply wiring itself.
3 Do not connect wires of different gauge to the same
grounding terminal. Looseness in the connection may
deteriorate the protection.
4 Remote controller cords and wires connecting the units
should be located at least 50mm away from power supply
wiring. Not following this guideline may result in malfunction
due to electrical noise.
5 For the remote controller wiring, refer to the "Installation
manual of the remote controller" supplied with the remote
controller.
Note
The customer has the ability to select the remote controller
thermistor (only for FHYCP35~125B7V1).
6 Never connect the power supply wiring to the terminal board
for transmission wiring. This mistake could damage the entire
system.
7 Use only specified wires and tightly connect wires to the
terminals. Be careful that wires do not place external stress
on the terminals. Keep wiring in neat order so that they do not
obstruct other equipment such as popping open the service
cover. Make sure the cover closes tight. Incomplete
connections could result in overheating, and in the worse
case, electric shock or fire.
WIRING EXAMPLE
For the wiring of outdoor units, refer to the installation manual
attached to the outdoor units.
Confirm the system type:
•
Pair type: 1 remote controller controls 1 indoor unit (standard
system).
•
Simultaneous operation system: 1 remote controller controls
2 indoor units (2 indoor units operate equally)
•
Group control: 1 remote controller controls up to 16 indoor
units (All indoor units operate according to the remote
controller).
•
2 remote controller control: 2 remote controllers control 1
indoor unit.
