  • Publication number: 20230341878
    Abstract: A chemical control system for an aquatic application is disclosed. The control system includes an enclosure having a graphic overlay and a reference chart disposed on a front cover thereof and a sensor in communication with the enclosure and designed to detect a level of a first chemical in the water of the aquatic application. A pump receives a signal to dispense at least one chemical into the aquatic application in response to feedback from the sensor to effectuate a change in the chemical composition of the aquatic application.

  • Patent number: 11687103
    Abstract: 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.

  • Publication number: 20220097264
    Abstract: The present invention contemplates a method of forming a member comprising injection molding a first layer into a first tool cavity, overmolding a second layer into a second tool cavity selected from the group consisting of an expandable layer, a sealing layer, an acoustic layer, and adhesive layer, a reinforcement layer, a fastening layer, a second carrier layer, and any combination thereof, overmolding a third layer into the second tool cavity selected from the group consisting of an expandable layer, a sealing layer, an acoustic layer, an adhesive layer, a reinforcement layer, a fastening layer, a second carrier layer, and any combination thereof. The first layer, the second layer, and the third layer may be molded in one injection molding tool and the second and third layer may be segregated from one another prior to any overmolding steps.

  • Patent number: 10990115
    Abstract: 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.

  • Publication number: 20190314243
    Abstract: 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.

  • Patent number: 10191498
    Abstract: A chemical controller for an aquatic application comprising at least one output relay. The chemical controller further includes a current detection circuit configured to detect current on an output of the at least one output relay and a current fault detection device configured to output a current fault signal indicative of the occurrence of a current fault condition. The chemical controller further comprises at least one relay latch configured to receive the relay enable signal and the current fault signal and to decouple the relay enable signal from a corresponding relay latch output when the current fault signal indicates the occurrence of a current fault condition. A relay drive circuit is configured to receive a signal from the corresponding relay latch output to and to responsively activate and deactivate the at least one output relay.
