US Patent 9423805 Wall-mounted controller with a removable portion

An example wall-mountable HVAC controller may include a controller module and a wall plate, with a hinge that allows the controller module to rotate relative to the wall plate. The hinge may provide an end stop that limits the rotation of the controller module relative to the wall plate, and/or may allow the controller module to be freely pulled away and disengaged from the wall plate if desired.
