When building occupants need quick, easy interaction with building systems in an office, conference room, or other defined zone, vSTAT® from American Auto-Matrix® offers the easy, user-friendly iPhone® or Android™ application. Simply by scanning a QR Code®, a tenant can access the controls for a zone without the need to locate a wall-mounted unit or computer.
