A pool or spa system includes networked pool or spa devices that can be dynamically configured with network addresses by a controller. The controller can transmit a device discovery request on a network and can receive a discovery response from pool or spa devices that require a network address. The system determines and assigns the network addresses for the pool or spa devices based on unique device identifiers associated with the responding pool or spa devices. The network addresses assigned to the pool or spa device are transmitted to the pool or spa device to be used by the pool or spa devices to communicate with the controller over the network. The system can be used to discover and assign addresses to various types of pool or spa devices, such as pumps, underwater lights, chlorinators, water feature controllers, remote controllers, and/or other types of devices.

Spa systems may be used all year round and in colder weather provide an enjoyable experience for users through the cold ambient outdoor temperature and the heated water of the spa. However, failures in respect of the water circulating pump and/or heater of the spa system either mechanically, electrically or through overall power outages mean the water in the spa system and its pipework can easily freeze if ambient conditions are cold enough leading to cracks in the spa system or pipes and hence leaks when the water thaws requiring costly repair or replacement of components or entire systems. Accordingly, a freeze protection system is provided that uses a backup thermal management system discretely or in combination with other backup systems. These freeze protection systems offering backup when mechanical failures, electrical failures etc. arise by providing thermal input to the spa system through alternate thermal paths and providing alarms.

A steam therapy assembly includes a housing that has an intake and an exhaust to pass air through the intake and the exhaust. A water tank is removably attachable to the housing and the water tank has a fluid port to pass water therethrough for filling the water tank with water. An oil cartridge contains oil and the oil cartridge is removably insertable into the housing. A vaporizing unit is integrated into the housing and the vaporizing unit is in fluid communication between the intake and the exhaust to urge air into the intake and outwardly through the exhaust when the vaporizing unit is turned on. The vaporizing unit vaporizes the water in the water tank into a steam. Additionally, the vaporizing unit vaporizes the oil in the oil cartridge thereby mixing the vaporized oil with the vaporized water.

One aspect of the invention provides a computer-implemented method for controlling a swimming pool or spa system. The computer-implemented method includes: creating a data structure representing a plurality of swimming pool system components and fluidic connections between subsets of the plurality of swimming pool system components; receiving a request to control one or more of the plurality of swimming pool system components; calculating fluidic flows through the plurality of swimming pool system components based on one or more potential configurations of the plurality of swimming pool system components capable of fulfilling the request; and detecting whether the one or more potential configurations result in unsatisfactory conditions.

A method, apparatus and system to facilitate maintenance of a network enabled bathing unit system. A Graphical User Interface (GUI) is presented providing a user operable control for receiving from a customer a service request requesting that a technician contact the customer. The user operable control may in some cases be enabled in response to detection of an operational error in the bathing unit system and disabled otherwise. In response to receipt of the service request through the user operable control, a notification message indicating that the customer has requested to be contacted by a technician is sent over a communication network. In some embodiments, a message responsive to the service request is received to cause the GUI to present user-selectable options to enable the customer to selectively permit the remote control and monitoring of the bathing unit system by a specific remote service technician.

A hands-free visual timer enables a person to wash his or hands for the duration of time recommended by the Center for Disease Control. Upon activation, the timer displays an annular ring of thirty triangles and a first icon. After five seconds have passed, a second icon is displayed indicating the user should apply soap. After twenty-five seconds, a third icon is displayed indicating the user should rinse. After thirty seconds, the screen goes blank and all the triangles have disappeared. The central display of triangles is illuminated by a liquid crystal display. The icons are illuminated by light emitting diodes.

The foot spa has a rotating drive hub and a pump. The hub has North and South pole domains encircling a rotation axis in alternating relation. The pump includes a housing and an impeller, the housing having a pair of sides and defining: a cavity having a center and a periphery; an intake that communicates with the cavity center; and one or more ports communicating with the periphery. The impeller is mounted in the cavity and: defines blades which are adapted, upon rotation of the impeller in the cavity, to draw water through the intake and eject water through the one or more ports; and includes a portion that is ferromagnetic and a portion that is not ferromagnetic, the portions: being adapted such that rotation of the drive hub causes rotation of the impeller and abutting one another, one being axially displaced from the other.

A method and a control panel are described for facilitating the control of a bathing unit system so that the bathing unit system is caused to transition between operating in accordance with a first operational mode to operating in accordance with a second operational mode. A control signal is generated in response to a unitary user input event performed by a user at a control panel of the bathing unit system, the control signal conveying an ambiance activation command associated with a specific ambience setting, the generation of the control signal comprising selecting the specific ambience setting from a set of ambience settings stored in a memory device. The control signal is then transmitted from the control panel to the controller over a communication link where it is processed to cause the bathing unit system to transition from being in the rest mode to operating in accordance with the specific ambience setting. The method and a control panel may allow simplifying the control of the bathing unit system in order to achieve a desired total effect by allowing a user to cause the bathing unit to operate in accordance with an ambience setting by way of a unitary user input event performed at the control panel.

A steam shower device includes a steam enclosure, including a front plate with first and second vacuum air vents, a rear wall, and a steam chamber; a steam mixing valve with a steam control dial; a mixed water line; a steam nozzle assembly with a stem nozzle head; a steam vent, including a perimeter wall and a perimeter ledge; a visual trim panel; a hot water pan; such that the steam vent is configured to emit steam from the steam chamber. Optionally, the steam shower device can include a hand-held steam hose, which is detachably connectable to the steam vent.
