摘要:
A user adjustable visual display system and method for a digital thermostat having a backlit user display screen and system operation indicators is provided. The system allows a user to programmatically vary the illumination intensity of the backlit user display screen and the operational indicators. The variance provided includes disabling of the backlight and operational indicators. The system utilizes a variable pulse width modulated (PWM) intensity control for the backlight and indicators. Alternatively, an adjustable current drive illumination control is used to control the backlight and indicators. The selection of the desired intensity is provided via a display settings menu accessed via the user display screen.

A thermostat that can display information in multiple different orientations is provided. The thermostat includes a housing, a display, and an input device. As the housing is mounted in a particular orientation, the thermostat changes the orientation of the information for properly displaying same to a user. This is accomplished by sensing the orientation of the housing in one embodiment, and through user selection of a desired orientation in another embodiment. A separate display and input device(s) are provided in one embodiment, and a combined touch screen display and input device is provided in another embodiment.

A visual display system for use with a digital thermostat is provided. The visual display system provides an adjustable display resolution for the temperature readout provided thereon. This adjustable display resolution may be changed as desired by a user via a resolution adjustment menu. The display resolution may be adjusted to display the temperature information in tenths of degrees, half degrees, whole degrees, etc. as desired by a user. Such a display system accommodates different display resolution requirements of different original equipment manufacturer (OEM) customers who may desire different displayed resolutions without having to manufacture and stock different models.

An integrated lighting control and threat detection system is provided. Once one of the threat detectors determines that a hazardous condition exists, it transmits a threat message to the lighting control system. The lighting control system then operates to turn on illumination within the dwelling to aid in an occupant's safe exiting from the dwelling. The lighting control system operates to illuminate all lights within a dwelling upon detection of a hazardous condition. Alternatively, the lighting control system operates to illuminate preselected paths of lighting as programmed by a user. Still further, coordinated illuminated control may be provided based upon the location of the detected hazardous condition and the fixed and portable lights within a dwelling. Both fixed and adaptive illumination control are provided as is a fail safe illumination of all lights within a dwelling should each of the pre-selected exit paths contain a hazardous condition.

The system of the present invention provides energy saving control for a water heater via an intelligent thermostat. This intelligent thermostat provides programmatic control over the HVAC system as is conventional, and provides coordinated control over the water heater temperature set point. This control over the water heater is accomplished via a communications network between the intelligent thermostat and the water heater. In one embodiment the communications are wireless, although wired and network bus communications may also be utilized. Enhanced and coordinated control is also provided so that different operational temperature cycles can be provided to coordinate with the intelligent thermostat's programmatic control of the HVAC system. Separate programmatic control of the water heater is also provided whereby different operational temperature modes may be commanded, e.g. Wake, Sleep, and Demand modes of operation.

An appliance diagnostic display and interface system providing a centralized user interface for appliance diagnostic information and control of system self-tests is provided. This centralized user interface is provided via an intelligent thermostat that includes an LCD display. The intelligent thermostat interfaces, via wireless or wired communications, with the appliances installed in the home. The intelligent thermostat then generates and displays various user interface screens that allow particular appliances to be selected. Separate appliance specific screens are then generated that allow the user to access the diagnostic information in system test functionality provided by the individual appliance. Soft function keys provided on the intelligent thermostat allow multi-functional access to the features of the invention depending on which screen is currently being displayed.

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.

Upon detection of a flammable gas condition, an intelligent thermostat regulates operation of appliances that have sources of ignition which could be the source of or may ignite the flammable gas. This hazardous condition is detected by a flammable gas detector and is 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 provide a visual warning user interface screen to inform the occupant of the hazardous condition, and may signal smoke detectors in the dwelling to sound an audible flammable gas warning. Alternatively, the flammable gas detector may signal the smoke detectors in the dwelling to sound an audible flammable gas warning directly.
摘要:
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.

Upgraded firmware for a microcontroller is created and encrypted to construct a file (116) that can be distributed and installed by technicians in the field. The encryption includes character encryption (210) of the data as well as a second level of block encryption (216). Within the encrypted file (116), information about the firmware and the target microcontroller (104) is included. The distributed firmware file (116) is stored on a portable device, such as a PDA, that can communicate with the target microcontroller (104) to effect a firmware transfer from the PDA (112) to the microcontroller (104). The microcontroller (104) includes a programming routine that receives the encrypted data stream from the PDA and decrypts the data before storing the new firmware image. The programming routine also identifies when updating the firmware has left the firmware in an unusable condition and prevents operation of the microcontroller until the firmware is restored. Accordingly, the security of the firmware is maintained throughout the distribution and upgrade process and the integrity of the upgrade process is maintained as well.
