Abstract
An HVAC controller receives signals from a plurality of sensors positioned in different spaces. The HVAC controller includes a housing and a user interface that is accessible from an exterior of the housing. A controller is configured to control the HVAC system using a control temperature that comprises a weighted combination of two or more of the current temperatures reported by the plurality of sensors. The controller tracks which of the different spaces are currently occupied and how long each of the currently occupied spaces have been occupied, and as a currently occupied space remains occupied for a longer period of time, the controller provides increasing weight over time to the current temperature reported by the sensor of the plurality of sensors that is in that currently occupied space, and controls the HVAC system in order to drive the control temperature towards a temperature set point.
