Product Bulletin Issue Date September 1, 2009 © 2009 Johnson Controls, Inc. 1 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. Figure 1: LN Series Sensor (LN-SENSOR-0) Features and Benefits Durable Hardware Features robust ABS resin casing and allows easy connection Status Light-Emitting Diode (LED) Features an externally powered 24 VAC/VDC 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 Code No. LIT-1201874 www.johnsoncontrols.com Overview The modern, attractive, low profile enclosure is suitable for classrooms, hotels, executive areas, office spaces, and other commercial areas. Mounting hardware with a separate subbase is provided with the units for installation on drywall or a 2 in. x 4 in. electrical junction box.
