Abstract: 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.

Abstract: A control system for a mitigation device includes a processor and a computer-readable medium that includes instructions executable by the processor. The instructions include monitoring a first measured particulate matter (PM) level of a conditioned space. The first measured PM level includes PM having a first range of sizes. The instructions further include monitoring a second measured PM level of the conditioned space. The second measured PM level includes PM having a second range of sizes. The first and second ranges are different but overlapping. The instructions also include asserting, in response to the first measured PM level being greater than a first predetermined threshold, an activation signal. The activation signal forces operation of a fan of the mitigation device. The instructions include asserting, in response to the second measured PM level being greater than a predetermined percentage of the first measured PM level, the activation signal.

Abstract: First and second IAQ sensors are located within a building and are configured to measure first and second IAQ parameters, respectively, the first and second IAQ parameter being the same one of: relative humidity; amount of particulate; amount of volatile organic compounds; and amount of carbon dioxide. A mitigation device is separate from an HVAC system and includes a control module configured to turn the mitigation device on and off based on the first IAQ parameter, the second IAQ parameter, and whether the HVAC system is on or off. A mitigation module is configured to selectively turn the HVAC system on and off based on the second IAQ parameter, the first IAQ parameter, and whether the HVAC system is on or off.
