Product Description 
These room units allow users to view and adjust 
points in the controller using the room unit buttons 
and digital display. 
They work with various Terminal Equipment 
Controllers (TECs) and Actuator Terminal 
Controllers (ATECs) offered by Siemens Industry, 
Inc. These devices incorporate a solid state or 10K 
NTC sensing element to detect temperature (and 
humidity for QFA models). The effective sensing and 
setpoint range is 55°F to 95°F (13°C to 35°C). 
These room units can be mounted on electrical 
boxes, stud-type mounting brackets, or drywall. 
Obtain the necessary mounting hardware and follow 
the appropriate mounting procedures for the type of 
installation required.
