Abstract: A vacuum cleaner includes a housing, a debris chamber defined within the housing, a filter disposed within the debris chamber, a motor assembly including a motor and an impeller connected to the housing and operable to generate airflow through the debris chamber and filter, a voltage sensor positioned to detect an input voltage applied to the motor, a temperature sensor positioned to detect a temperature associated with the motor and a controller communicatively coupled to the voltage sensor, temperature sensor, and motor. The controller includes a processor and memory having instructions that program the processor to determine a threshold temperature based at least in part on the input voltage detected by the voltage sensor, compare the temperature associated with the motor to the threshold temperature, and output a warning that the filter is full of debris when the temperature associated with the motor exceeds the threshold temperature.

Abstract: An example HVAC system includes a furnace including a gas valve, a circulator motor to circulate air through the HVAC system, and a current sensor configured to detect a current supplied to the circulator motor. The system also includes a controller configured to disable the gas valve when a detected current supplied to the circulator motor is outside of a specified operating current range. A detected current to the circulator motor outside of the specified operating current range is indicative of a malfunction of the circulator motor. Example methods of operating a gas valve in an HVAC system are also disclosed.

Abstract: A thermostatic expansion valve includes an operating rod, a recessed receiver portion, and a first metering pin positioned at least partially within the receiver portion to selectively contact the operating rod. The first metering pin includes a base diameter, an overall length, and a taper portion. The taper portion is tapered at a specified degree relative to a longitudinal axis of the first metering pin. The thermostatic expansion valve is adapted to operate at a first specified refrigeration tonnage when the first metering pin is positioned at least partially within the receiver portion, and to operate at a second specified refrigeration tonnage when the first metering pin is replaced with a second metering pin including a different taper portion than the first metering pin.

Abstract: A circulator blower controller for a circulator blower of a heating, ventilation, and air conditioning (HVAC) system of a building includes an interface configured to receive a demand signal with an operating mode from a thermostat. A switching circuit selectively connects power to a tap of a motor of the circulator blower. A data store configured to store a mapping from a speed to the tap. For each tap, a processor observes power consumed by the circulator blower while power is connected to the tap by the switching circuit. The processor determines the mapping by sorting the taps based on observed power consumption. The processor selects a first speed based on the demand signal from the thermostat. The processor identifies a first tap from the mapping based on the first speed and generates the tap selection signal to control the switching circuit to connect power to the first tap.
