    摘要： A failsafe hydrocarbon-based gas (HBG) leak detection (HLD) and mitigation (HLM) system/method for use in heating, ventilation, and air conditioning (HVAC) systems that incorporates a hydrocarbon gas sensor (HGS), sensor signal conditioner (SSC), alarm status indicator (ASI), and digital control processor (DCP) is disclosed. The HGS detects ambient hydrocarbon gas (AHG) and presents a hydrocarbon sensor voltage (HSV) to the SSC. The DCP and SSC form a closed control loop (CCL) in which the SSC electrical characteristics are adjusted by the DCP such that the HSV is continuously and dynamically recalibrated to account for background HBG levels, changes in ambient air conditions, HGS manufacturing tolerances, and other field-specific operational conditions that impact the HGS detection capabilities. The DCP is configured to log alarms to the ASI if a HGS HBG leak is detected and optionally shutdown gas flow to one or more HBG target (HBT) system components.

    摘要： 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.
