Modular room control interface and sensors

A room control interface, comprising:

• a base component having a base room control function;
• and
• a face component removably attached to the base component, the face component having a user interface and/or a room control function that is different from the base room control function;
• wherein the face component is selected from one of a first face component including a first user interface and/or a first room control function and a second face component that is interchangeable with the first face component, the second face component including a second user interface and/or a second room control function that is different from the first user interface and/or the first room control function, respectively.

A building management system, comprising:

• at least one control subsystem;
• at least one local controller connected to the at least one control subsystem;
• and
• a plurality of modular room control interfaces connected to the at least one local controller, each modular room control interface comprising a base plate having a base room control function and a face plate removably attached to the base plate, the face plate having a user interface and/or a room control function that is different from the base room control function;
• wherein the face plate is selected from one of a first face plate including a first user interface and/or a first room control function and a second face plate that is interchangeable with the first face plate, the second face plate including a second user interface and/or a second room control function that is different from the first user interface and/or the first room control function, respectively.
