Multi-function thermostat with occupant tracking features

A thermostat controller for a building, the thermostat controller comprising:

• a user interface configured to receive user input adjusting settings of the thermostat controller;
• a communications interface configured to:
• communicate with building equipment and receive data from one or more sensors;
• and
• receive preferences of a first occupant from a building management system;
• and
• a processing circuit configured to:
• control the building equipment to affect an environmental condition within a first zone of the building based on the preferences of the occupant when the first occupant is detected by the processing circuit within the first zone based on the data received from the sensors;
• detect whether a second occupant associated with no permission to adjust the settings is within a predefined distance from the thermostat controller based on the data received from the sensors;
• disable adjustment of the settings via the user interface in response to a detection that the second occupant is within the predefined distance from the thermostat controller;
• detect movement of the first occupant from the first zone of the building to a second zone of the building based on the data received from the sensors;
• and
• control the building equipment to affect an environmental condition within a second zone of the building based on the preferences of the first occupant when the occupant is detected within the second zone based on the data received from the sensors.

A method for controlling building equipment with a multi-function thermostat for a building, the method comprising:

• receiving, by the thermostat, user input adjusting settings of the thermostat via a user interface of the thermostat;
• operating, by the thermostat, the building equipment to affect an environmental condition within a first zone of the building when a first occupant is detected by the thermostat within the first zone based on occupancy data;
• detecting, by the thermostat, whether a second occupant associated with no permission to adjust the settings is within a predefined distance from the thermostat based on the occupancy data;
• disabling, by the thermostat, adjustment of the settings via the user interface in response to a detection that the second occupant is within the predefined distance from the thermostat;
• detecting, by the thermostat, movement of the first occupant from the first zone of the building to a second zone of the building based on the occupancy data;
• and
• operating, by the thermostat, the building equipment to affect an environmental condition within the second zone of the building when the first occupant is detected within the second zone based on the occupancy data.
