Siemens AQA2200-2X4 Room Unit Back Plate Assembly

Siemens AQA2200-2X4 Room Unit Back Plate Assembly is a 3-1/2 x 5 inch trim plate that serves as the mounting back plate for Siemens Series 2200/3200 room sensors. This 2x4 wall-box adapter plate is designed to be installed behind the Room Unit Base to secure the unit to a standard 2x4 wall box and ensure proper alignment. The INTL variant is offered as the AQA2200-INTL Room Unit Back Plate (10-pack), matching the same mounting geometry used with Siemens TECs and related 2200/3200 room sensors in commercial environments. When mounting, align the top and bottom mounting holes for a precise fit before attaching to the wall, and follow NEC/local electrical codes for wiring. The back plate provides a stable, code-compliant foundation for room unit installation, enabling clean cable routing and reliable operation of temperature/room-sensing hardware in Siemens building technologies projects.
