Patent number: 7579956Abstract: Upon detection of a high carbon monoxide condition, an intelligent thermostat regulates operation of appliances that have sources of combustion which could be the source of or may exacerbate the high carbon monoxide condition. This hazardous condition is detected by a detector and communicated to the intelligent thermostat by wired or wireless communications. The intelligent thermostat then communicates with these appliances either via wired or wireless communications. The intelligent thermostat may also operate a ventilation system to flush the environment with fresh air to minimize or eliminate the hazardous condition. External and internal temperature sensors allow coordinated operation of the ventilating and heating systems to flush the environment with fresh air without causing a freezing condition to exist within the environment.Type: GrantFiled: January 6, 2005Date of Patent: August 25, 2009Assignee: Robertshaw Controls CompanyInventors: John Gilman Chapman, Jr., Nicholas Ashworth, Robert Burt, Timothy E.

Publication number: 20070241203Abstract: An HVAC system comprises a programmable wireless thermostat and a remote receiver unit. The thermostat includes a user interface having one or more displays, user input devices, such as buttons, sliders, or a touch screen, and a backlight. The thermostat may include a proximity sensor, wherein the user interface is controlled based on a user's presence near the thermostat. A thermostat controller enters into a reduced energy consumption mode and switches the user interface to an idle state when the proximity sensor indicates a lack of user proximity for a predetermined duration. When the proximity sensor indicates user proximity, the controller exits the reduced energy consumption mode and switches the user interface to an active state. During the reduced energy consumption mode, the user interface may be concealed when the user interface is in a housing which is transparent when backlit but is opaque otherwise.Type: ApplicationFiled: April 14, 2006Publication date: October 18, 2007Applicant: Ranco Inc. of DelawareInventors: Phillip Wagner, John Chapman, Joseph Rao, Nicholas Ashworth

Patent number: 7265678Abstract: An intelligent thermostat communicates with battery-powered threat detectors, such as smoke detectors, to allow remote quieting and coordination of a low battery warning detected by the threat detector. In one embodiment, the threat detector transmits a pre-warning signal to the thermostat indicating that a low battery condition is imminent. The thermostat uses this information to display a pre-warning to the consumer so that the consumer may better coordinate replacing of the battery at a convenient time. Once a low battery condition has been detected, the threat detector transmits a low battery warning signal to the thermostat. The thermostat then displays a warning message and an option for the consumer to quiet the chirping for a period of time from the thermostat. Preferably, the thermostat automatically quiets the chirping during quite times so as to not disturb the consumer.Type: GrantFiled: January 6, 2005Date of Patent: September 4, 2007Assignee: Maple Chase CompanyInventors: John Gilman Chapman, Jr., Nicholas Ashworth, Robert Burt, Timothy E.
