PENTAIR WATER POOL AND SPA, INC.

A system and methods of remotely monitoring and controlling a pool controller for a pool or a spa via one or more remote computing devices is provided. In some embodiments, a remote user can be provided with information about the pool or the spa. The remote user is provided with an ability to remotely optimize a performance of the pool or the spa, including remotely adjusting a chemistry of the pool or the spa, remotely activating a heater of the pool or the spa, and/or remotely activating a pump of the pool or the spa.

Apparatuses and methods for filter detection are provided. A filter detection system includes a filter for a pump, the filter having a filter element, and an identification element associated with the filter. A controller is designed to detect the identification element, determine a filter characteristic based on the identification element, determine a remaining lifetime period of the filter element based on the filter characteristic and a runtime of the pump, and provide an alert indicating the remaining lifetime period of the filter element.

A system for analyzing the water quality of a water sample is provided. The system includes an inlet designed to deliver the water sample to a photometric analyzer, a chemical reagent system downstream of the inlet and upstream of the photometric analyzer, and a controller. The chemical reagent system is designed to inject one or more reagents into the water sample. The photometric analyzer comprises a vial designed to contain the water sample, at least one light source designed to emit light toward a first side of the vial, and at least one light detector designed to detect the emitted light on a second side of the vial. The controller is configured to adjust a dosage of the one or more reagents injected into the water sample, receive data from the at least one light detector, and analyze the water quality of the water sample based on the received data.

In some embodiments, a remote user can be provided with information about the pool or the spa. The remote user is provided with an ability to remotely optimize a performance of the pool or the spa, including remotely adjusting a chemistry of the pool or the spa, remotely activating a heater of the pool or the spa, and/or remotely activating a pump of the pool or the spa.

An apparatus and method for filter detection are provided. The filter detection system includes a filter provided in the form of a filter element, a housing surrounding the filter element, and an identification element. A controller is designed to detect the identification element, determine a filter characteristic based on the identification element, determine a remaining lifetime period of the filter element based on the filter characteristic, and provide an alert indicating the remaining lifetime period of the filter element.

An apparatus and method for bather load detection are provided. In one instance, a method for determining bather load in a pool comprises calculating a first permeability of a membrane filter at a first period of time by measuring a pressure differential across a membrane filter located in the pool, measuring a flow rate of pool water through the fluid circuit formed by the pool, determining a volume of the membrane, calculating a second permeability of a membrane filter at a second period of time, calculating a difference between the first permeability and the second permeability, and determining a bather load based on the calculated difference between the first permeability and the second permeability.

A connected aquatic equipment system is provided. The connected system includes system components, such as pool equipment, which can be automatically detected and configured based on identification elements and operating parameters of the pool components. The connected system can update the configuration settings of the pool components based on the addition of new pool components. The connected system is also designed to monitor and update the operating parameters of the pool components based, at least in part, on the status and performance of other pool components of the system.

A water quality monitor for a swimming pool is disclosed. The water quality monitor has a base having a first end and a second end, a removable cover coupled to and enclosing the first end of the base, a flow cell jar extending from the second end of the base, and a sensor probe connected to the second end of the base and extending downwardly into the flow cell jar. The sensor probe is configured to measure a plurality of water quality parameters. The monitor further includes a debris filter provided in a fluid flow path between an inlet and a first side of the base, and a controller configured to provide a connection between the water quality monitor and a cloud storage system using a wireless network. The measured plurality of water quality parameters are transmitted through the wireless network to the cloud storage system.

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.

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.
