540-650B | Room Temperature Sensor, White | Siemens

Room Temperature Sensor, White

This Series 2000 Room Temperature Sensor provides an interactive digital link to terminal Equipment Controllers (TEC) that allows viewing and adjustment of controller points directly from the sensor's liquid crystal display and keypad. These sensors incorporate a precision thermistor to accurately and reliably measure room temperature. The sensor measures 3-11/32 high x 2-1/2" wide x 1-1/2" deep, has a white plastic cover, and a temperature monitoring range from 55 to 95 degrees Fahrenheit (13 to 35 degrees Celsius)."

Description

The Series 2000 Room Temperature Sensors provide an interactive digital link to Terminal Equipment Controllers (TECs) that allows viewing and adjusting controller points directly from the sensor’s liquid crystal display and keypad. These sensors incorporate a precision thermistor to accurately and reliably measure room temperature.

Features

• Programmable Liquid Crystal Display (LCD): A two-line alphanumeric LCD allows simultaneous display of room temperature, a user-selected critical point, and day/night operation status. You can configure the screen to:
  - show English or metric units,
  - turn the room temperature display on or off,
  - select a critical point for display, or
  - turn off the critical point display.
• Digital setpoint adjustment: The sensor’s keypad allows error-free digital setpoint adjustments in one-degree increments. Setpoint values momentarily display as changes are made.
• Display of operating mode: Graphic symbols are displayed to indicate the controller’s operating mode. A “sun” indicates occupied mode operation and a “moon” indicates night mode operation.
• Override button: A flush-mounted override button allows you to change to an occupied control schedule during the unoccupied cycle for a period of time determined by the system operator.
• Passkey security: A special hardware passkey plugs into the sensor’s MMI port to allow access to the display configuration menu and the controller’s point database.
