Patent number: 11687103Abstract: A method of controlling an output relay of a chemical controller is disclosed. The output relay is coupled to a pump configured to introduce at least one chemical into the aquatic application. The chemical controller controls the operation of the pump using the output relay. The method includes the step of utilizing a watchdog timer circuit to determine that a processor has failed to send a reset signal to the watchdog timer circuit before a timer of the watchdog timer circuit reaches zero. The method further includes the step of outputting a processor fault signal from the watchdog timer circuit.Type: GrantFiled: April 27, 2021Date of Patent: June 27, 2023Assignee: PENTAIR WATER POOL AND SPA, INC.Inventors: Keith Lewis, Greg Lyons

Patent number: 10990115Abstract: A chemical controller for an aquatic application comprising an output relay. The chemical controller further includes a current detection circuit configured to detect current on an output of the output relay and a current fault detection device configured to output a current fault signal when a current fault condition has occurred. A relay latch of the chemical controller receives the relay enable signal and the current fault signal and decouples the relay enable signal from a corresponding output when a current fault condition has occurred. A relay drive circuit receives a signal from the corresponding output to responsively activate and deactivate the output relay. A watchdog timer circuit causes the output relay to be deactivated in response to detecting a hung processor.Type: GrantFiled: January 28, 2019Date of Patent: April 27, 2021Assignee: Pentair Water Pool and Spa, Inc.Inventors: Keith Lewis, Greg Lyons

Publication number: 20190314243Abstract: Systems and methods are provided for the control of pool/spa device circuits. A control system may control such circuits in response to command data received from local or remote client devices. Feature circuits and light groups may be defined via a user interface to include a group of pool/spa device circuits or light circuits, respectively. Activating a feature circuit may involve performing an associated logic function. Multiple feature circuits may be assigned to a feature circuit group which, when activated, may activate all feature circuits assigned to the feature group. The control system may control the performance of freeze protection and automatic cleaner functions, and may control light circuits to synchronized, color-changing light effects. Commands may be issued to the control system and system data may be stored and retrieved from a remote database via web servers, web application programming interface servers, and/or inter-server communication buses.Type: ApplicationFiled: April 17, 2019Publication date: October 17, 2019Inventors: David MacCallum, Ed Brown, Keith Lewis
