Publication number: 20240353137Abstract: A method of conditioning air includes controlling, by a thermostat, an HVAC system to condition the air within an enclosed space according to one or more temperature setpoints stored in a memory of the thermostat and the temperature within the enclosed space. Weather data for outside the enclosed space is received and compared to a previously received preference. The HVAC system is controlled to condition the air according to the one or more temperature setpoints and the temperature within the enclosed space when the weather data does not satisfy the preference. When the weather data satisfies the preference, the user is notified that heating or cooling by the HVAC system will be turned off and that the user should open the at least one opening to outside of the enclosed space, and the thermostat controls the HVAC system to stop conditioning the air.Type: ApplicationFiled: April 18, 2023Publication date: October 24, 2024Inventors: Daniel E.

Patent number: 9037303Abstract: Exemplary embodiments are disclosed of a control for an HVAC system. The control has an alphanumeric display, a plurality of two position switches (e.g., push buttons, etc.), and a processor. The processor receives a current user input through at least one of the two position switches and determines a response to the current user input. The determining is performed using one or more previously received user inputs, if any, via one or more of the two position switches. The processor implements the determined response by displaying a message on the alphanumeric display and/or changing an operational parameter of the HVAC system.Type: GrantFiled: June 28, 2012Date of Patent: May 19, 2015Assignee: Emerson Electric Co.Inventors: William C.
