Siemens Building Technologies Series 2300 Data Sheet
Standard Room
Temperature Systems
Series 2300
QAA23SS.FWNN
Temperature Room Unit.
Description
Series 2300 Temperature Room Units offer simple
temperature sensing functionality. These devices work with
most building automation systems to deliver exceptional
occupant comfort. All room units incorporate precision
temperature sensing elements to accurately and reliably
measure room temperature. Their compact, low-prole
design results in an attractive, inconspicuous installation.
Strategically placed ventilation slots in the housing
optimize airow through the cover for fast measurement
response and superior control.
Features
• Resistive output signals
• Selectable voltage or current output models
• High degree of accuracy
• Analog temperature display
• Organic light emitting diode
• Analog setpoint adjustment
• Occupancy override button
• Dim or brighten display
• Show or hide OLED display elements
• Local setpoint limiting
• Numerical or graphical display of temperature setpoint
Applications
These room units connect to the controllers input points
via free wire cabling, which is landed on the controllers’
terminal block connector.
