Programming Instructions for Wall Control Unit (WC100)
8
Normally there will be only one Wall Control Unit
connected to Control Board. Multi Wall Control Unit (up to
three) is also supported (see page 2). All Wall Control
Units will have the same priorities over each other. It
means that if multiple Wall Control Units command
Control Board differently, the latest command will be
executed by the Control Board. Each Wall Control Unit
has different address for communication purpose. The
addresses for Wall Control Units will be A1,A2, and A3.
The addresses can be set by entering into programming
mode (see page 7).
