OPERATION MANUAL CENTRAL REMOTE CONTROLLER MODELS DCS302CA61 Read these instructions carefully before installation. Keep this manual in a handy place for future reference. This manual should be left with the equipment owner.
BEFORE USE 䡲 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.
∗ 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.
