The Controller Board is a Neuron-based platform that
executes a zone level application and allows
communication to all LonMark devices. The
controllers are shipped with pre-loaded applications
reducing engineering start-up time.

Room Sensor Port
The room sensor connection to the Controller Board
consists of a quick-connect RJ-11 jack. This
streamlines installation and reduces LTEC start-up
time.

Spare Input/Output Points
The LTEC controller, depending upon the application
used, may have up to 3 input and 2 output spare
points available. These points can be used to perform
local connection and network control for devices
located in close proximity to the LTEC controller,
therefore reducing costs associated with installation.
