3 Connecting to the Indoor Unit
1. Connect to the connector CN32 on the indoor controller board.
2. Press the connector for the remote ON/OFF adaptor into the CN32 connector.
The connector can only be connected in one direction only. Do not force the connection.
4 Locally Procured Wiring
With the remote ON/OFF adaptor, variations of connection method with the locally
installed circuit will provide different types of operating configurations.
Example: External timer operation, remote control operation
1. Basic Connection Method
SW1 - Operating switch
Performs operation/stopping of indoor unit.
SW2 - Selecting switch
For selecting whether the operation/stopping is to be performed by external circuit
or remote control.*
* Also includes system controller (central controller).
2. Switch Settings (Refer to table at right for details.)

Since this is not used, be sure to
completely wrap with insulation tape
If SW2 is on, operation cannot be performed
by the remote controller.
If SW2 is off, operation is permited.
Use a momentary switch (a switch that is turned on manually and
turns off automatically) for SW2.
Press SW2 (for 1 second or more) and the operation starts. After
this, the remote controller can be used for operations.
In either case, there is a 5 to 6 second delay from the time when the operating command is sent until the unit operates.
1. To perform operation/stopping by only remote operation or external timer and to prohibit operation/stopping by the remote
controller, use the following circuits.
2. To perform operation/stopping by remote operation or external timer and allow operation/stopping by the remote
controller, use the following circuits.
3. To start operation by remote operation and then freely use remote controller, use the following circuit.
4. To permit/prohibit the use of the remote
controller by an external circuit.

Keep the length of wire from the circuit board of the indoor unit within 10 meters. Excessive length could cause improper operation.
Use a transit relay when extending wiring such as remote wiring.
