The Johnson Controls LP-NRM052-000C Network Room Module (NRM) is an electronic, wall mount temperature sensor designed to work directly with Facility Explorer field controllers. Monitors room or space temperature, and displays the room temperature and local setpoint. Graphical display symbols indicate fan speed selection and the need for maintenance. Optional operating controls include a dial to locally adjust the space temperature setpoint, a push button to manually override the fan speed, and a push button to select °F or °C units of measure.
The LP-NRM052-000C connects from the Remote Display link of the Facility Explorer field controller. Locate terminals in the mounting base for ease of wiring. The LP-NRM052-000C is enclosed in an attractively styled plastic housing, which easily mounts on a wall.
