Abstract: Devices and methods for assessing the performance and efficiency of an HVAC system using a tuple including a percentage of runtime over a lookback window coupled with a ?T value for the difference between the HVAC setpoint and the outdoor temperature. The performance monitoring may be done using a device that is independent of the HVAC thermostat or may be incorporated within a smart thermostat. Trends in measured tuples over time can warn of system degradation.

Abstract: A method of operating a tankless beverage brewing apparatus that includes a digital controller for dynamically varying the water temperature and/or the brew flow rate of the dispensed beverage is shown. In some embodiments, a main supply line of the tankless beverage brewing apparatus includes a pressure reducer, a pressure sensor, a linear heater, a temperature sensor, and a spray valve; all supplying a hot water spray head and/or a hot water spigot. The inlet of the main supply line of the tankless beverage brewing apparatus may be connected directly to the local cold water supply. The controller uses feedback from the temperature sensor and/or the pressure sensor to dynamically vary the water temperature and/or the brew flow rate depending on the type of beverage being brewed.

Abstract: An interactive programmable beverage brewing apparatus providing audible setup and control instructions for ease of use is presented. The beverage brewing apparatus includes the ability to audibly instruct a user in the steps for setup of the beverage flavor characteristics when a beverage is to be brewed, and provide audible instructions in the use of the machine during normal brewing operations. The beverage brewing apparatus also provides a visual display to present phrases and icons to assist the user in performing setup and brew operations in conjunction with the audible instructions. Visual phrases and icons presented to a user also provide instruction in how to setup and control timers and how to turn on and off one or more warming plates to keep a beverage hot during and after brewing.
