4. 2. 2. External output
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 25 m (82 ft.).
• Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed.
• Output voltage: Hi DC12V±2V, Lo 0V.
• Permissible current: 50mA

4. 2. 3. Connection methods
■
Wire modi
fi
cation
• Remove insulation from wire attached to wire kit connector.
• Remove insulation from locally purchased cable. Use crimp type insulated butt
connector to join
fi
eld cable and wire kit wire.
• Connect the wire with connecting wire with solder.
IMPORTANT:
Be sure to insulate the connection between the wires.
Locally purchased
Option parts
External output wire
Solder and insulate the connected parts.
• Connecting wires to the terminals.
Use ring terminals with insulating sleeves to connect to the terminal block.
• Connection terminals and wiring arrangement
In following
fi
gure, all the possible connections are done for description.
In actual installation, connections will differ according to each installation requirements.
4. 3. Remote sensor
Remote sensor
• Remove the existing connector and replace it with the remote sensor connector (ensure
that the correct connector is used).
• The original connector should be insulated to ensure that it does not come into contact
with other electrical circuitry.
Setting for room temperature correction
When a remote sensor is connected, set the function setting of indoor unit as indicated
below.
• Set Function Number “30” (Room temperature control for cooling) to “00”
• Set Function Number “31” (Room temperature control for heating) to “01”
5. REMOTE CONTROL INSTALLATION
CAUTION
• Be sure to turn off the electrical breaker before making settings.
• When setting DIP switches, do not touch any other parts on the circuit board directly
with your bare hands.
5. 1. Group control
CAUTION
Group control is only possible between units with remote controllers of the same type.
To con
fi
rm the type of remote controller, see the back of the remote controller or
“2. 5. Optional parts”.
A number of indoor units can be operated at the same time using a single remote controller.
(1) Connect up to 16 indoor units in a system. (indoor unit to remote controller)

(2) Set the R.C. address (DIP switch setting)
Set the R.C. address of each indoor unit using the DIP switch on the indoor unit
circuit board.

(a) 2-wire type
DIP switch (RC AD SW)...Factory setting “00”
Since the remote controller address settings are automatically con

If con
fi
guring manually, it is necessary to con
fi
gure both the indoor unit and the remote
controller. For details, please refer to the remote controller installation manual.
(b) 3-wire type
DIP switch (RC AD SW)...Factory setting “00”
When connecting multiple indoor units to 1 standard wired remote controller, set the
address at RC AD SW in sequence from “00”.
