Control Devices
3. MAIN/SUB Changeover Switch Setting
With two unified ON/OFF controllers, centralized control (indoor units) is possible from different locations. In this kind
of set-up, it is necessary to set the MAIN/SUB changeover switch.
One of the two unified ON/OFF controllers (1) · (2) is set to “MAIN” while the other is set to “SUB”.
4. Setting of the Sequential Operation Function
The unified ON/OFF controller 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.
5. Control Mode Selector (DS2)
The following four patterns of control mode can be set.
Note:
„

Set control mode before turning power supply ON.
„
When used in conjunction with central remote controller, the control modes of the central remote controller has the
priority.
6. Forced Reset Switch (SS1)
When changing the setting of the connector for setting master controller, etc., you can reset simply by setting it to the
reset side once and returning to the normal side, without turning the power OFF.
(For normal operation, set the switch to the normal side.)

Remote Controller
Content Operation/stop is
controlled by both unified
ON/OFF controller and
remote controller. After operated by unified
ON/OFF controller,
operation/stop is freely
controlled by remote
controller until stopped by
unified ON/OFF controller. When used in conjunction with
schedule timer, operation/stop
is controlled freely by remote
controller during the set time
but operation is not available
when schedule timer is ON. Operation/stop is controlled by
unified ON/OFF controller only.
(This unit can not be operated/
stopped by remote controller.)
