LN Series Sensors
LN Series Sensor
Description
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.
Features
• durable hardware — features robust ABS resin casing and allows
easy connection
• status Light-Emitting Diode (LED) — features an externally powered
24 VAC/VDC 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
