BEFORE USE

n GENERAL DESCRIPTION OF SYSTEM

This central remote controller can monitor and control up to 64 indoor unit groups.
Using two central remote controllers allows monitoring and controlling of up to 128 indoor unit groups.

Main Functions

1. Batch starting and stopping of indoor units connected to the central remote controller.

2. Handling of operation settings such as start/stop, timer operation, remote controller prohibition/permission, etc.,

and operation status settings such as temperature.

3. Operation status monitoring of operation mode, set temperature, etc.

4. Can be connected to an external central monitor panel and key system using the forced stop input

(non-voltage a connector).

• When using 1 central remote controller

• When using 2 central remote controllers

(The central remote controller and the separately sold remote control adapter circuit board or group remote con­trol adapter cannot be used together.)

∗ GROUP OF INDOOR UNIT refers to the below.

1. A single indoor unit without remote controller

English 2

∗ Zone control from the central remote controller

Zone control is available from the central remote controller. With it, it is possible to make unified settings for mul­tiple groups, so setting operations are greatly simplified.

• Any setting you make within a given zone will apply to all groups in the said zone.

• A maximum of 64 zones can be set from a single central remote controller.

(Each zone contains a maximum of 64 groups.)

• Zones can be set randomly from the central remote controller.
