Abstract: The disclosed technology includes a controller configured to control an output of one or more boilers to reduce temperature overshoot of the boiler system. The controller can receive temperature data, a threshold temperature value, and a maximum temperature value, and determine whether the temperature of the water in the boiler system is greater than or equal to a threshold temperature. The controller can also determine a number of operating boilers that were operating when the threshold temperature was reached and determine a temperature increment value based on the threshold temperature, the maximum temperature, and the number of operating boilers. The controller can output a control signal to a boiler to reduce an output of the boiler based on the temperature increment value and the temperature data to reduce overshoot of the boiler system.

Abstract: The disclosed technology includes systems and methods for operating a pool water heating system. The pool water heating system can include a heat pump, a supplemental heat source, a water temperature sensor, and a controller. The controller can be configured to receive water temperature data and, in response to determining that the temperature of the water is less than a threshold temperature, output a control signal to activate the heat pump. The controller can further determine an expected heating time that can be indicative of an amount of time required for the temperature of the water to be greater than or equal to the threshold temperature. The controller can also generate a heating schedule based at least in part on the expected heat time and a predetermined time of use. The heating schedule can be indicative of a heat pump operation time and a supplemental heat source operation time.

Abstract: Systems and methods for dynamic boiler control are disclosed. The system can receive flue gas data from a flue gas sensor and can receive blower data associated with a blower of the boiler. The system can determine, based at least in part on the blower data, a current fire status of the boiler and can provide one or more fire-status-specific parameters based on the current fire status of the boiler. The system can compare the flue gas data to a target flue gas value, and in response to determining that the flue gas data is less than the target flue gas value, the system can execute one or more boiler operation rules using the one or more fire-status-specific parameters. The system can output instructions for adjustment of an air-fuel ratio of the boiler based on the boiler operation rules and the one or more fire-status-specific parameters.

Abstract: Systems and methods for boiler regulation are disclosed. The system can receive boiler data from a boiler and compare the boiler data to a normal operating range to detect an abnormality. Based on a plurality of rules, the system can identify an anticipated root cause and at least one corrective action. Based on the at least one corrective action, the system can generate and/or output instructions for the boiler to perform the at least one corrective action. The system can display an indication of the abnormality and/or the at least one corrective action.

Abstract: The disclosed technology includes a controller for a cascade boiler system having both condensing and non-condensing boilers. The controller can receive supply water temperature data and return water temperature data to determine a current temperature differential in the system. The controller can determine a current load demand value using the current temperature differential and a set point temperature. If the current load demand value is less than or equal to a first load demand threshold, the controller can output a control signal for a condensing boiler to transition to a heating mode. If the current load demand value is greater than a second load demand threshold, the controller can output a control signal for a non-condensing boiler to transition to a heating mode.

Abstract: Systems and methods for monitoring anodic protection are disclosed. The system can include a sacrificial anode having an anode body, at least one cavity within the anode body, a conductor disposed within the at least one cavity, and electronic circuitry in communication with the conductor. The sacrificial anode can be electrically connected to a component or structure that is subject to galvanic corrosion. The cavity can be positioned such that as the anode degrades to a certain point, the conductor will contact water. In response, an alert can be provided to inform a user that the sacrificial anode needs replacement. The alert can be provided by activating a light, siren, or other device. The alert can also be sent to a mobile device or website.
