Room sensors QFA3280.FWSC RH 2%, for TEC, Digital signal, Sense & Display, Override, Temp Setpoint, Tool Port

Room sensors QFA3280.FWSC RH 2%, for TEC, Digital signal, Sense & Display, Override, Temp Setpoint, Tool Port

Description
These Series 2200/3200 Room Sensors are designed for
use with Siemens Terminal Equipment Controllers
(TECs)*. The sensor and controller communicate using
an RJ-11 cable with plug connections at both ends for
easy and error-free wiring. Installation is quick and
straightforward with all hardware included for mounting
on a standard 2” × 4” electrical box. Screws and anchors
are provided for mounting the sensor directly to a wall.
Matching gaskets and trim rings are also available.
All units include an RJ-11 tool port at the bottoms of the
sensor housings for connection to Siemens
configuration, commissioning and start-up tools.
QAA Series Sensors measure room temperature while
QFA Series sensors measure both temperature and
relative humidity. The QPA Series Sensors measure
temperature and CO2 or temperature, CO2* and relative
humidity.
QPA Series sensors are designed to help maintain
occupant comfort and are not intended for use in life
safety applications.
The “E” versions have a blank front to prevent
unauthorized adjustments and are ideal for high traffic
areas or remote spaces that are not supervised.
The “D” versions display room temperature and/or room
humidity.
The “F” versions feature a full HMI that can display room
conditions and temperature setpoint. The display is
easily configured to limit the information that is available
to the occupant. Temperature setpoint can be adjusted
using soft touch plus (+) and minus (-) keys, and an
override key enables the user to manually signal to the
controller that the space is occupied.
