Identication and Overview
BAPI’s Echelon® compatible “L-Temp” Room Unit features measurement
and display of local temperature (°C or °F), as well as display of outdoor
temperature and outdoor humidity – all in one aesthetically-pleasing
package.
An onboard Neuron® chip allows connection directly to a LonWorks® network
using star, bus, or loop topology. Additional options include Temperature
Setpoint and Local Override as well as Fan Speed Control for Fan Coils,
Heat Pumps, Unit Ventilators or other Terminal Units. The Fan Speed is
provided as a Network Variable and includes appropriate LCD Indicators.

each hole.
3. Drill the 1/2” hole for the wires and pull the wire through the wall and
out of the 1/2” hole, leaving about 6” free.
4. Pull the wire through the hole in the base plate.

5. Secure the base to the drywall anchors using the #6 x 1 inch
mounting screws provided.
6. Terminate the unit according to the Termination guidelines in on pg 2.
7. Attach Cover by latching it to the top of the base, rotating the cover down and snapping it into place.
8. Secure the cover by backing out the lock-down screws using a 1/16” Allen wrench until they are ush with the
bottom of the cover.
NOTE: In a wall-mount application, the wall temperature and the temperature of the air within the wall cavity
can cause erroneous readings. The mixing of room air and air from within the wall cavity can lead to
condensation, erroneous readings and premature failure of the sensor.
To prevent these conditions, seal the
conduit leading to the junction box.
