A vacuum appliance comprising a drum and a vacuum head. The drum may include a base and a cylinder sealed to the base. The vacuum head may include a lid and a blower. The lid preferably includes a portion that is detachably mounted to an open upper end of the drum. The blower may be mounted to, atop, or within the lid. In any case, the blower induces a vacuum within the drum and moves through the vacuum. The base or the cylinder may include a drain to drain fluid and debris contained within the drum. The lid may include a lower portion sealed to and defining the open upper end of the drum. The cylinder or the lid may include an air inlet through which the blower draws air and entrained debris.


Disclosed are exemplary embodiments of apparatus and methods for remote testing of controllers such as thermostats, to detect incorrect climate control system configuration parameters. In an exemplary embodiment, a computer wirelessly connects with a remote thermostat and sends signal(s) to the thermostat instructing the thermostat to perform climate control function(s) in predefined sequence(s). The computer receives signal(s) from the thermostat indicating whether the thermostat is performing the climate control function(s) in accordance with the sent signal(s). Based on the signal(s) received from the thermostat, the computer determines whether the thermostat is configured with accurate climate control system configuration parameters.

In exemplary embodiments, methods for operating driving controls for communicating motors are disclosed. In an exemplary embodiment, a method generally includes controlling a transmit circuit of the driving control to generate an expected transmit signal for sending to the communicating motor, and detecting, using a transmit sense circuit in the driving control, the actual resulting signal generated by the transmit circuit signal before the actual resulting signal leaves the driving control and is transmitted to the communicating motor. The method also includes analyzing the detected signal to verify whether the transmit circuit in the driving control is working properly, by comparing the expected transmit signal to the detected actual resulting signal. Exemplary methods are also disclosed of analyzing receive circuits of driving controls to verify whether the receive circuits are working properly.


Disclosed are exemplary embodiments of systems and methods for dynamically displaying informational content on a controller display. In an exemplary embodiment, a climate control system controller generally includes a display and at least one sensor configured to detect a user within a vicinity of the climate control system controller. A distance is determined between the climate control system controller and the detected user. Based on the determined distance, a first or a second display component arrangement is shown on the display. Informational content of the second display component arrangement differs at least in part from informational content of the first display component arrangement.

An example rotary actuator includes a cam that is to be coupled to a valve. The cam is rotatable about an axis. The example rotary actuator also includes a linear actuator having a stem movable along a path offset from and perpendicular to the axis and a chain having a first end and a second end opposite the first end. The first end of the chain is coupled to the stem and the second end of the chain coupled to the cam. The chain is disposed around at least a portion of an outer edge of the cam, and movement of the stem along the path rotates the cam about the axis.

A system and method for monitoring a heating, ventilation, or air conditioning (HVAC) system of a building is provided. A monitoring server, located remotely from the building, receives operating parameter data from a monitoring device at the building that measures an operating parameter of the HVAC system. The monitoring server generates a plurality of data clusters from the operating parameter data, each data cluster corresponding to operating parameter data generated during steady-state operation of the HVAC system. The monitoring server calculates an average operating parameter value for each data cluster. The monitoring server calculates normalized operating parameter values based on normalizing the average operating parameter values for the data clusters over a predetermined normalization time period. The monitoring server compares the normalized operating parameter values with a threshold. The monitoring server determine whether an air filter of the HVAC system needs to be replaced based on the comparison and generates a notification based on the determination indicating that the air filter needs to be replaced.

Exemplary embodiments are disclosed of a climate control system that includes an igniter and a controller having an igniter relay. The controller senses a current level through the igniter and senses voltage between terminals of a second relay of the controller. In a given one of a plurality of operational phases of the system, the controller is configured to compare the sensed current level and sensed voltage to a current level and voltage associated with a specific condition of the igniter, igniter relay, or second relay in the given phase. Based on a result of the comparing, the controller is configured to distinguish between a failure of one of the relays and a failure of the igniter.
