  • Publication number: 20150204564
    Abstract: A graphical user interface system for a thermal comfort controller. The user interface system has a central processing unit coupled to a memory and a touch sensitive display unit. The memory stores a temperature schedule data structure and perhaps a temperature history data structure. The temperature schedule data structure is made up of at least one set-point. The temperature history data structure is made up of at least one Actual-Temperature-Point. The display presents the set-points and/or the Actual-Temperature-Points. One representation of the display is a graphical step-function. The user uses a finger or stylus to program the set-points by pointing and dragging a portion of the step-function.

  • Patent number: 7320110
    Abstract: A multiple language user interface system for a thermal comfort controller. The user interface system has a central processing unit coupled to a memory, a language selector and a touch sensitive display unit. The memory can store at least one user interface object and at least one control algorithm. In some embodiments, the user interface system also has a network interface for connecting to the Internet or other network. In some embodiments, the first time the user interface system is powered-up after installation, a first set of user interface objects are displayed on the display unit and the user selects a preferred language. Once a preferred language is chosen, user interface objects can be loaded into the memory and the display unit will display the user interface objects in the preferred language. In some embodiments, control algorithms are loaded into memory.

  • Patent number: 6557771
    Abstract: A controller for a climate control system has a humidity temperature sensor as well as a dry-bulb temperature sensor. A humidity temperature value is used in connection with a dry-bulb temperature value to generate an error signal that is a function of either the dry-bulb or the humidity temperature values. This permits control of both enclosure temperature and enclosure humidity without abnormal cycling of the climate control system. The humidity temperature can synthesized from the relative humidity and dry-bulb temperature within the enclosure.

  • Publication number: 20030019359
    Abstract: A robust, relatively simple air quality control system that can control the air quality in buildings during both the heating and cooling seasons. In one illustrative embodiment, a first air stream is directed through an air treatment module and back into the inside space. A desiccant in the air treatment module adsorbs water, volatile organic compounds and/or particulate material from the first air stream. A second air stream is then directed through the air treatment module to a location outside of the inside space. The second air stream is preferably heated relative to the first air stream so that at least a portion of the adsorbed water, volatile organic compounds and/or particulate material are desorbed from the desiccant into the second air stream. The second air stream carries the desorbed water, volatile organic compounds and/or particulate material to a location outside the inside space.

  • Patent number: 5737934
    Abstract: A controller for a climate control system has a relative humidity sensor as well as a dry-bulb temperature sensor within the enclosure. The humidity value is used in conjunction with the dry-bulb temperature to generate an apparent temperature error signal which is a function of both the dry-bulb temperature and the relative humidity values. This permits robust control of both enclosure temperature and enclosure moisture content without abnormal cycling of the climate control system. Instead of using a sensor which directly measures the apparent temperature, the apparent temperature can be synthesized from the relative humidity and dry-bulb temperature within the enclosure. Alternately, the sensed and set point apparent temperature values can be synthesized from any two thermodynamic properties of the moist air within the enclosure.

  • Patent number: 5675979
    Abstract: A controller for a climate control system has a relative humidity sensor as well as a dry-bulb temperature sensor within the enclosure. The humidity value is used in conjunction with the dry-bulb temperature to generate an enthalpy error signal which is a function of both the dry-bulb temperature and the relative humidity values. This permits robust control of both enclosure temperature and enclosure humidity without abnormal cycling of the climate control system. Instead of using a sensor which directly measures the enthalpy, the enthalpy can be synthesized from the relative humidity and dry-bulb temperature within the enclosure. Alternately, the sensed and set point enthalpy values can be synthesized from any two thermodynamic properties of the moist air within the enclosure.

  • Patent number: 5555927
    Abstract: An adaptive recovery method for a setback thermostat using the intersection of the space temperature with a sloped recovery temperature line which approximates the change in temperature as a function of time during recovery of the temperature controlled space from a setback temperature, to determine the time at which recovery to the occupancy temperature should begin. The thermostat starts recovery when the current space temperature crosses the recovery temperature line. A useful feature of the apparatus and method which implement the invention, computes and constantly updates the slope of the temperature recovery line. The update of the temperature recovery line slope is based on miss time, i.e.
