3. Connecting to the Remote Controller
1. Connect to the connector CN2 on the Remote controller board.
2. Press the connector for the Timer Adapter into the CN2 connector.
The connector can only be connected in one direction only. Do not force the connection.

4. Locally Procured Wiring
With the Timer Adapter, 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).

SW2 - If on.
• Operation/stopping cannot be controlled from
remote controller.
Other operations (such as temperature settings
and changing fan speed) can be performed.
• Operation/stopping can be performed by SW1.
SW2 - If off.
• Operations can be performed from
remote controller.
• Operation/stopping cannot be
performed by SW1.
5. Examples of Usage
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.

3. To start operation by remote operation and then freely use remote controller, use the following circuit.
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.

If SW2 is on, operation cannot be performed
by the remote controller.
If SW2 is off, operation is permited.

6. Wiring Restrictions
Keep the length of wire from the circuit board of the indoor unit within 10 meters (32ft). Excessive length could cause improper operation.
Use a transit relay when extending wiring such as remote wiring.
