[CHECK 8] Master Unit Central Connector Setting Table
The master unit central setting connector (CN1/X1A) is mounted at the factory.
•
To independently use a single unit of the intelligent Touch controller or a single unit of the
central remote controller, do not dismount the master unit central setting connector (i.e., use
the connector with the factory setting unchanged).
• To independently use the schedule timer, insert an independent-use setting connector.
No independent-use setting connector has been mounted at the factory. Insert the
connector, which is attached to the casing of the main unit, in the PC board (CN1/X1A).
(Independent-use connector=Master unit central setting connector)
• To use two or more central equipment in combination, make settings according to the table
shown below.
(*1) The intelligent Touch controller and the schedule timer are not available for combined use.

unit central setting connector" at the factory. The schedule timer has been set to "Not provided with the master unit central setting
connector" at the factory, which is attached to the casing of the main unit.
