    摘要: An indoor air quality (IAQ) system for a building includes an IAQ sensor that is located within the building and that is configured to measure an IAQ parameter. The IAQ parameter is one of: an amount of particulate of at least a predetermined size present in air; an amount of volatile organic compounds (VOCs) present in air; and an amount of carbon dioxide present in air. A mitigation module is configured to: selectively turn on a mitigation device based on a comparison of the IAQ parameter with a first ON threshold and a second ON threshold; and selectively turn off the mitigation device based on a comparison of the IAQ parameter with an OFF threshold. A clean module is configured to determine a clean value for the IAQ parameter. A thresholds module is configured to, based on the clean value, determine the first ON threshold and the OFF threshold.

    摘要: An HVAC controller is configured to receive signals from a plurality of sensors positioned in different spaces. The HVAC controller includes a controller that is configured to display one or more screens on a user interface that include a home screen including a selectable display element that indicates a number of the plurality of sensors that are currently being used by the controller in controlling the HVAC system. Upon selection of the selectable display element, the controller displays a sensor priority screen that includes a plurality of graphic constructs that each identify a building space and a current temperature for that building space. The controller is configured to control the HVAC system in accordance with the current temperature reported by each of the number of the plurality of sensors that are currently being used by the controller in controlling the HVAC system.

    摘要: An actuator in a HVAC system includes a mechanical transducer, a processing circuit, a wireless transceiver, and a power circuit. The processing circuit includes a processor and memory and is configured to operate the mechanical transducer according to a control program stored in the memory. The wireless transceiver is configured to facilitate bidirectional wireless data communications between the processing circuit and an external device. The power circuit is configured to draw power from a wireless signal received via the wireless transceiver and power the processing circuit and the wireless transceiver using the drawn power. The processing circuit is configured to use the power drawn from the wireless signal to wirelessly transmit data stored in the memory of the actuator to the external device via the wireless transceiver, wirelessly receive data from the external device via the wireless transceiver, and store the data received from the external device in the memory.

    摘要: An environmental control system for a building including heating, ventilation, or air conditioning (HVAC) equipment that operates to affect a temperature of a zone of the building. The system includes a temperature sensor to measure the temperature and a controller including a processing circuit. The processing circuit is configured to operate the HVAC equipment based on a temperature setpoint and gather training data indicating system dynamics. The processing circuit is configured to monitor a temperature tracking error of the zone and a heat transfer value of the HVAC equipment and determine if the HVAC equipment is in a saturation region based on the temperature tracking error and the heat transfer value. The processing circuit is configured to, in response to a determination that the HVAC equipment is in the saturation region, calculate an adjusted temperature setpoint and operate the HVAC equipment based on the adjusted temperature setpoint.

    摘要: An HVAC controller includes a first input terminal configured to be electrically coupled with a first field wire and a second input terminal configured to be electrically coupled with a second field wire, and a double pole relay including two input terminals and two output terminals. Control circuitry is operably coupled to the temperature sensor and the double pole relay and is configured to determine whether the first field wire is electrically coupled with the first input terminal and whether the second field wire is electrically coupled with the second input terminal.
