The complete line of LN Series, LONWORKS® based
devices includes programmable controllers,
application-specific controllers, displays, schedulers,
and programmable thermostats. This product line is
easily integrated into the Metasys® system when
coupled with a LONWORKS enabled Network
Automation Engine (NAE).
The complete family of LN Series controllers is
designed for use with any LONWORKS network open
and interoperable system.

Scheduler and Display
The LN Series of programmable and application
specific controllers are complimented by the Display
and Scheduler that help manage facility events and
provide a straightforward user interface where
authorized building occupants can interact with building
systems.
The LN Series Scheduler is a LONWORKS based node
capable of storing and managing up to 16 schedules.
The Scheduler is initially configured through an LNS
plug-in to any LNS Network Management software,
including LN Builder (Figure 5).                                    Figure 6: Metasys System LN Series

The LN Series Display is an extension of the
Scheduler. The Display node provides the scheduling
capabilities of the Scheduler, and also incorporates an
integral display and buttons to serve as a local user
interface to your Metasys system. The Display is
capable of displaying and providing the ability to
manipulate many variables associated with the
operation of your facility.
