TCX865 Series Controllers
The TCX865 series includes the TCX865, TCX866, TCX867, TCX868 and
TCX869 controllers. Like the TCX860 series, the TCX865 series controllers are
used to control VAV boxes. The TCX865 series communicates with the
CX9200, as well as other Infinet controllers, via the Infinet network. The
TCX865 series can be used in a dedicated or a non-dedicated smoke control
application.
The TCX865 series controllers have a built-in motor and gear assembly for
direct control of a damper.
