Abstract

An HVAC controller includes (1) an interface coupled to an air quality sensor proximate to the premises and coupled to a data source external to the HVAC system, the interface configured to receive environmental data from both the air quality sensor and the external data source and (2) a processor configured to automatically operate a demand unit of the HVAC system based on the environmental data.
