Management of a thermostat's power consumption
InactiveUS20070241203A1Reduce energy consumptionAdditional level of power conservationTemperature control without auxillary powerMechanical apparatusProximity sensorUser input
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.

A thermostat may be placed in a heating mode when the sensed temperature is less than the lowest of the heating and cooling target temperatures by a first amount and may be placed in a cooling mode when the sensed temperature is greater than the highest of the heating and cooling target temperatures by a second amount. The presence or absence of a user may be monitored. If the thermostat is in a user absent mode, a cool setback amount may be added to the cooling target temperature and a heat setback amount may be subtracted from the heating target temperature to arrive at setback cooling and setback heating target temperatures, respectively. The thermostat may comprise a touch-sensitive screen having various display areas.

The programmable thermostat instructs the HVAC system to adjust the temperature of the area within the structure based on the state of occupancy of that particular area to enhance occupant comfort and energy efficiency. The thermostat may also include programming modes or scripts that may be run to adjust operational control when abnormal occupancy conditions are sensed. Controllable dampers may also be used by the thermostat to achieve micro zoning control of the HVAC system.

Self-programmable thermostat
ActiveUS7784704B2Minimize the numberEasy to useTemperature control without auxillary powerMechanical apparatusHabitEngineering
A hybrid manual / programmable thermostat for a furnace or air conditioner offers the simplicity of a manual thermostat while providing the convenience and versatility of a programmable one. Initially, the hybrid thermostat appears to function as an ordinary manual thermostat; however, it privately observes and learns a user's manual temperature setting habits and eventually programs itself accordingly. If users begin changing their preferred temperature settings due to seasonal changes or other reasons, the thermostat continues learning and will adapt to those changes as well. For ease of use, the thermostat does not require an onscreen menu as a user interface. In some embodiments, the thermostat can effectively program itself for temperature settings that are set to occur at particular times daily or just on weekends, yet the user is not required to enter the time of day or the day of the week.

Systems and methods are described for interactively and graphically interfacing with a user on an HVAC system controlled by a thermostat. The user interface is implemented on a touch screen display on a remote wirelessly connected device such as smartphone or a tablet PC. The interface displays a screen that mimics the display on the thermostat including allowing one or more input methods that are analogous to input methods used on the thermostat. Touch screen gestures such as touch and drag, touch and hold and tapping are used in an intuitive way. The user experience is enhanced by allowing large-scale changes while reducing the risk of sudden unintended changes. The control signals are judiciously tailored to protect the HVAC equipment from unwarranted over-controlling, reduce unnecessary network traffic, and prevent the waste of energy.

A proportional valve is disclosed for controlling the outlet pressure of a fluid flowing therethrough. The valve comprises a valve body having an inlet port and an outlet port for the fluid. The valve also has an inner chamber, within which there is formed a valve seat that may be opened and closed variably by a shutter axially movable from and towards the valve seat. Movement of the shutter is controlled by a shape memory alloy (SMA) actuating member operating antagonistically to an elastic member, the temperature of the fluid being lower than the transition temperature of the shape memory alloy. The actuating member and the elastic member are connected to the body valve at opposite sides relative to the valve seat. A power control circuit is also provided for circulating an electric current through the actuating member so as to heat the same by Joule effect from a temperature lower than the transition temperature to one that is higher. At least one vent hole is formed in the valve body for putting a portion of the chamber upstream of the valve seat into fluid communication with the outside or a collection network. The actuating member is housed in that portion of chamber corresponding to the inlet port of the fluid, whereby a continuous flow of fluid around the actuating member is ensured for accelerating the cooling process. A closed-loop control circuit for the power control circuit controls the circulating current as a function of a pressure signal generated by fluid pressure sensing means and in such a way as to offset the retarding effect produced by the fluid during heating of the actuating member.

Two-wire power and communication link for a thermostat
InactiveUS20080054084A1Temperature control without auxillary powerMechanical apparatusTelecommunications linkCommunication link
A single pair of polarity independent wires conveys electrical power and two-way communication between a remote thermostat and a temperature-conditioning unit. The system is functional even if the wires are crossed, so mis-wiring is nearly impossible. The system is selectively operable in three independently distinct modes: a power mode for conveying electrical power from the temperature-conditioning unit to the thermostat, an output mode for transmitting a communication signal from the temperature-conditioning unit to the thermostat, and a feedback mode for conveying a communication signal from the thermostat to the temperature-conditioning unit. When the power mode is inactive during the output mode and feedback mode, the thermostat relies on electrical power that the thermostat stored during a previous power mode. Communication is provided by a current loop circuit that is generally immune to electrical noise and tolerant of wire impedance.
