Disclosed are methods for measuring building health index using some mandatory and set of optionally configured parameters and utilizing building monitoring system having a connection to sensors in or pertaining to a building, and including central computing environment and one or more display devices showing the measurement. A building utilizing this method may be installed with one or more sensors, and which may be communicating to a locally installed communication device or a centrally installed computing environment that can collect the measurements over a period.

In some examples, a device controls a heating, ventilation, and air conditioning (HVAC) system within a building. The device includes an analog display including a set of markers, a stepper motor, and a pointer connected to the stepper motor. Additionally, the device includes processing circuitry configured to control the stepper motor in order to cause the pointer to indicate a first marker of the set of markers, wherein the first marker corresponds to a current parameter value and control a dial to indicate a set point parameter value by indicating a second marker of the set of markers which corresponds to the set point parameter value.

A system that allows a contractor to remotely monitor and/or interact with its customers' building control systems, such as heating, ventilating and air conditioning (HVAC) systems, and analyze information obtained from the building control systems over time. Such a system may help the contractor monitor and diagnosis customer building control systems, setup service calls, achieve better customer relations, create more effective marketing opportunities, as well as other functions. In some cases, the disclosed system may include a controller that analyzes data from HVAC systems, determines a thermal model of a space environmentally controlled by an HVAC system, and provides an energy audit of the space that is environmentally controlled by the HVAC system. The controller may output a result of the energy audit to a user.

A control system has an air conditioner that communicates with a file server via a network. The file server includes a lifestyle log in which information associating lifestyle information indicating a lifestyle with a control method of the air conditioner is accumulated. A first control-operation functional unit operates the air conditioner based on a first control request acquired from a first device. A second control-operation functional unit selects a control method from the lifestyle log based on a second control request acquired from a second device with higher functionality than the first device, and operates the air conditioner using the selected control method.

A communication kit comprising a communication module configured to communicate with a thermostat, an indoor unit, and an outdoor unit; and a controller configured to generate an operation signal to be transmitted to the indoor unit and the outdoor unit, based on a signal received from the thermostat, wherein the controller is configured to determine an operation mode of the indoor unit and the outdoor unit based on an indoor temperature when a backup function of the thermostat is executed.

A method/structure for calibrating a product fluid flow device having one or more apertures with aggregate area A.sub.o, where fluid flows along a fluid flow path therethrough in response to pressure differentials ΔP across the apertures. Calibration is effected relative to a calibration fluid flow device having a geometry and operational parameters corresponding to those of the product fluid flow device. A piecewise curved calibration controller establishes calibration conditions and generates a discrete point calibration flow rate (dpCFR) Function by measuring at a sparse set of points in a range of interest and determining a piecewise curved mathematical representation of fluid flow through the calibration fluid flow device. Data representative of the CFR function is transferred to a product blade controller, which processes the mathematical representation, and controls fluid flow through product fluid flow device based on values extracted from the received dpCFR Function.

A system of networked occupancy sensors and a thermostat that is controlled using data from the sensors. In a data network of occupancy sensors, the sensors (i) sense occupancy in a first space, such as a room within a building, and (ii) transmit data packets. Each of the data packets comprises an indication whose value is based in part on whether occupancy is sensed or not in the first space. The thermostat is situated in the first space and provides a control signal on an output line for controlling heating, ventilation, and air conditioning (HVAC), based on the temperature sensed by the thermostat. A controller unit comprises (i) a radio transceiver, capable of receiving the data packets, and (ii) a processor. The processor modifies the control signal on the output line of the thermostat, based in part on the value of the indication in the packets from the occupancy sensors.

A thermostat comprises a detachable dial control unit that may be positioned with an anchoring component. The anchoring component may assume different forms including a wall plate, a wireless recharging dock, or a headless control unit/wall mounted unit that serve different needs of a user. The detachable dial control unit may be removed while still allowing the user to change thermostatic settings of a heating, ventilation, and air conditioning (HVAC) system by rotating an outer ring indicative of thermostatic information and sending the information to a headless control unit/wall mounted unit via a wireless communication channel. To facilitate alignment of the detachable dial control unit with the anchoring component, each may comprise a plurality of alignment magnets having a magnetic polarity pattern. Also, a wireless charging dock and headless control unit/wall mounted unit may recharge the detachable dial control unit via an activated electromagnetic induction path.
