Abstract
A controller for an HVAC & R system is provided with the Internet connection to weather forecast information. The weather forecast information is utilized by the controller to take proactive steps in system operation and control. As an example, should the weather forecast information indicate that temperatures will be rising dramatically the next day, the controller may take the proactive step of increasing cooling in the conditioned space during the nighttime. In this manner, when the ambient temperature begins to rise the next day, the cooling load on the HVAC & R system components will be lower. Analogous proactive steps can be taken regarding humidity and fresh air circulation rate within the conditioned space. The present invention not only provides more prompt tailoring of the conditions within an environment to desired conditions, but also does so in a more efficient and less expensive manner
