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.

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, is configured to receive power consumption data and control signal data from a monitoring device at the building and to receive energy pricing data from a customer device associated with the HVAC system or a database that stores energy pricing data. The monitoring server is configured to determine energy cost data for segments of a selected time period based on the power consumption data, the control signal data, and the energy pricing data. The monitoring server is also configured to communicate the energy cost data to the customer device for display on the customer device.

In exemplary embodiments, HVAC controls and corresponding error detection methods are disclosed. In an exemplary embodiment, an HVAC control generally includes an analog input configured to receive an analog signal, and an error indicator. The control is configured to receive a neutral signal at the analog input, measure a voltage of the neutral signal with respect to earth ground, to operate the error indicator to provide a first indicator status indicative of a bad ground state if the voltage is between a first voltage threshold and a second voltage threshold, and to operate the error indicator to provide a second indicator status of a reverse polarity state if the voltage is above the second threshold. The HVAC control may include at least four different indicator statuses. The HVAC control may include a comparator.

Applicant has created vacuum apparatuses with improved stability and methods for improving the stability of a wet/dry vacuum. In one embodiment, the apparatus includes a motor, a removable drum adapted to store debris collected by the apparatus, and a base that can be adapted to receive the removable drum. The motor can be adapted to be interposed between the removable drum and the base. The methods can include the step of providing a base, the step of providing a removable drum adapted to be coupled to the base, and the step of coupling a vacuum motor to the base such that the vacuum motor is adapted to be disposed beneath the removable drum when the drum is coupled to the base. By relocating the motor of vacuum apparatus beneath the drum, the vacuums center of gravity can be lowered significantly and, thus, its propensity to tip over is minimized.
