Abstract: Disclosed are exemplary embodiments of methods for managing temperature overshoot. In an exemplary embodiment, a method includes determining a temperature delta between two sensor temperatures reported for a space at predetermined time intervals; determining a temperature rate of change by dividing the temperature delta with a time period that elapsed between the two sensor temperatures; determining a compensation by multiplying the temperature delta and the temperature rate of change; determining a compensated temperature by adding the compensation to a sensor temperature reported for the space; and using a controller and the compensated temperature to control operation of a heating system for the space.
Abstract: Exemplary embodiments are disclosed of controls including circuit assemblies configured for determining igniter, inducer relay, and igniter relay faults. In exemplary embodiments, a control for a system includes an input configured to receive a control signal, an inducer relay, an igniter relay, and a circuit assembly. The circuit assembly is configured to be coupled to the inducer relay, the igniter relay, and an igniter of the system. The circuit assembly comprises a plurality of diodes and is configured to enable detection of and distinguishing between a failure of the igniter, a failure of the inducer relay, and a failure of the igniter relay as determined by a waveform of the control signal at the input of the control for a given one of a plurality of operational states of the control.
Abstract: Disclosed are exemplary embodiments for monitoring for and/or detecting freeze-up and/or paddle wear conditions within dispensers and mixers associated with soft frozen desserts (broadly, edibles or edible products) and crushed ice drinks (broadly, drinkables or potable products).
Abstract: The present disclosure relates to controls and related methods for mitigating liquid (e.g., compressor refrigerant, etc.) migration and/or floodback.
