Abstract: A heating system for an aquatic application is provided in the form of a housing, a burner, an ignition control module, and a controller. The housing is in fluid communication with an inflow port and an outflow port. The burner is in fluid communication with a fuel source. The ignition control module includes a flame sense mechanism designed to determine a flame sense value. The controller is in electrical communication with the ignition control module and is designed to monitor one or more conditions related to the heating system.

Abstract: A connected heating system is provided. The system includes a heater having a first inflow port and a first outflow port, a controller that monitors one or more conditions relating to the heater, and a heater bypass coupled between the first inflow port and the first outflow port. The system also includes a valve that controls flow of water received from a pool into the first inflow port and the heater bypass based on operating state identified by the controller. In operation, responsive to the controller identifying the operating state, the controller is configured to transmit control signals that direct actuation of the valve to achieve the operating state. Additionally, the heater is configured to heat portions of the water from the pool that flow between the first inflow port and the first outflow port when a heating mode is active.
