5.2.3. Connection methods
■
Wire modifi 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 (Refer to “5.4. Other optional parts”)
5.3. Remote sensor (Optional parts)
5.3.1. Connection method
• 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.
• Connection terminals and wiring arrangement. (Refer to “5.4. Other optional parts”)
5.3.2. Setting for room temperature correction
When a remote sensor is connected, set the function setting of indoor unit as indicated
below.
• Function Number “30”:
Set the Setting Number to “00”. (Default)
• Function Number “31”:
Set the Setting Number to “02”.
* Refer to “7. FUNCTION SETTING” for details about Function number and Setting
