Control Devices
3.5 Initial Setting
1. Setting connector for individual use (X1A) (Factory set : OFF) (Set for individual use only)
For individual use of schedule timer
Insert the connector attached with the body case on the PC board.
For combined use with other optional controllers for centralized control
Do not change the factory setting.
2. Control mode selector (SS2) (Set for individual use only)
By changing the switch, setting mode of individual and centralized operation is available.
Note:
When used with other optional controllers, control mode of central remote controller and unified ON/OFF controller have
the priority.
3. Setting of the sequential operation function
The schedule timer is equipped with a sequential operation function that sequentially turns indoor units on in 2-second
intervals during unified operation.
(Sequential operation is factory set to “ON.”)
To switch sequential operation ON or OFF, set as follows.
Note:
The sequential operation function is designed to reduce the load on the power supply equipment, but does not guarantee
that compressors will not be started simultaneously. You cannot therefore count on a capacity reduction effect by power
supply equipment breaker selection.
4. Forced Reset Switch (SS1)
When changing the setting of the connector for individual use, etc., the switch can be reset simply by setting it to the
reset side once and returning to the normal side. This procedure enables to reset without turning off the power. (Set
the normal side at normal operation.)

5. Setting for special function
When you want to have a programmed operation of a part of indoor units by using only schedule timer, cut off J1 and
supply the power again.
You can have a programmed operation of the indoor units set the address for central control by local remote
controller.
