LN Series Sensors
The LN Series analog wall sensor family is specifically
designed to interface with fan coil, heat pump, roof top,
and other terminal unit building automation controls.
The units provide precise indoor local temperature
sensing. Local setpoint adjustment with various scales
is available as well.

(LN-SENSOR-0)
Features and Benefits
Durable Hardware Features robust ABS resin casing and allows
easy connection
Status Light-Emitting Diode Features an externally powered 24 VAC/VDC
(LED) LED for occupied/unoccupied system status
Tenant Override Button Provides an embossed membrane momentary
open switch which acts as a local override
button to current system status and operates
in parallel with the temperature sensor
