Abstract: A system includes a variable-capacity compressor operable at a first capacity and at a second capacity that is higher than the first capacity and an outdoor-air-temperature sensor. A control module receives a demand signal from a thermostat and operates the variable-capacity compressor in a first mode when communication with the outdoor-air-temperature sensor has not been interrupted and in a fault mode when communication with the outdoor-air-temperature sensor has been interrupted. In the first mode, the control module switches the variable-capacity compressor between the first capacity and the second capacity based on the demand signal and the outdoor-air-temperature data. In the fault mode, the control module operates the variable-capacity compressor by operating the variable-capacity compressor at least one of the first capacity and the second capacity based on the demand signal.

Abstract: A heating, ventilation, and air conditioning (HVAC) control system generates a request to replace a first air filter installed in an air handler of an HVAC system with a second air filter. The second air filter has a particulate matter removal efficiency rating that is greater than a particulate matter removal efficiency rating of the first filter. The system delays for a predetermined period of time and then obtains (i) a first temperature of air downstream of the air handler and (ii) a second temperature of air upstream of the air handler. The system then calculates a temperature difference between the f temperatures and determines whether the temperature difference is within an acceptable range. In response to the temperature difference being within the acceptable range, the system (i) operates the HVAC system using the second air filter and (ii) generates an alert indicating compatibility of the second air filter.

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.

The system may further include a first sensor producing a signal indicative of one of current and power drawn by the motor, a second sensor producing a signal indicative of a saturated condensing temperature, and a third sensor producing a signal indicative of a liquid-line temperature.
