Abstract: Tools and techniques are described to automate creation of point mapping diagrams between controllers and controlled resources. After receiving a defined space diagram (which may be input using a graphical interface of the controller, or by other means), resource locations and resource wiring requirements (which may be done automatically), a wiring diagram including point mapping between the resources and any necessary controllers is generated. If resources need to be moved, a new wiring diagram and/or point mapping can be regenerated.

Abstract: A system for detecting low IAQ and enabling ventilation in a multi-zone environment is disclosed. The system comprises dampers configured in supply air channels associated with zones of the environment, and an IAQ sensor configured in a common return duct associated with the environment. When the IAQ values of combined return air are detected to vary, a controller successively operates one of the dampers in an open state while operating remaining zone dampers in a closed state, so that supply air flows into the zone having zone damper in the open state. The controller further successively monitors IAQ values of the return air received from each of the zones and accordingly detects a low IAQ condition in the zones when a difference is detected between the IAQ values of the return air from the respective zone, and the IAQ values of the combined return air received collectively from the zones.

Abstract: Tools and techniques are described to automate commissioning of physical spaces. Controllers have access to databases of the devices that are controlled by them, including wiring diagrams and protocols, such that the controller can automatically check that each wire responds correctly to stimulus from the controller. Controllers also have access to databases of the physical space such that they can check that sensors in the space record the correct information for device activity, and sensors can cross-check each other for consistency. Once a physical space is commissioned, incentives can be sought based on commissioning results.

Abstract: The ionizer feedback control converts high-voltage signals to feedback signals to monitor the corresponding high-voltage signals and compares the feedback signals to a first specification to determine whether the feedback signals are within the first specification. The ionizer varies a frequency and a duty cycle of a digital signal to control an excitation signal for a step-up transformer and modulates the frequency and the duty cycle of a step-up transformer output voltage to consistently maintain the feedback signals within the first specification and maintain the high-voltage signals within a second specification to generate consistent ion concentrations over a range of electrical signal inputs. The microprocessor calculates and reports high-voltage signals, and ion concentrations based on feedback signals. The microprocessor monitors concentrations of Volatile Organic Compounds (VOCs) in an airflow serving the ionizer and adjusts the high-voltage signals and ion concentration when VOC concentrations are above a threshold.

Abstract: Methods and systems for maintaining an atmosphere inside a habitat enclosing a work station and shutting down one, more than one, or all operational equipment inside and/or outside the habitat upon the occurrence of an adverse event. Concentrations of explosive, flammable, and/or poisonous gases or vapors are sensed, transmitted to a logic device, as are temperature, pressure, and/or humidity. HVAC units and air extraction units controlled by the logic device maintain acceptable pressure, temperature, and/or humidity. Any grit and dust may be extracted. Any explosive, flammable, and/or poisonous gases or vapors are extracted employing an emergency gas extraction sub-system controlled by the logic device. The logic device shuts down one, more than one, or all operational equipment inside and/or outside the habitat (for example as dictated by the client, law, or regulation) upon receiving one or more adverse event signals.

Abstract: Embodiments include overflow sensor assemblies for water heaters, HVAC systems, and other devices for which temperature control systems may be used. An example overflow sensor assembly for detecting fluid leaks at a device may include a sensor probe configured to be in electrical communication with a power supply, and a sensor mounting bracket that forms a ground, where the sensor mounting bracket is configured to be adjustably coupled to a mounting surface on the device, such that the sensor mounting bracket can deflect about the mounting surface. The sensor probe is suspended from the sensor mounting bracket.
