Description
Series QAA2200 Room Temperature and Series
QFA3200 Room Humidity + Temperature sensors are
engineered to enable accurate and efficient control of
room comfort. A wide variety of output signals is
available for compatibly with nearly any control
system. The patented housing design seamlessly
blends into any décor and features strategically
placed ventilation slots to maximize airflow and
optimize accuracy.
The QFA3200 units combine a temperature sensor
with a relative humidity sensor in a single housing to
reduce installation time and improve overall room
aesthetics.
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.
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 “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.
