Abstract: The present invention provides apparatus featuring a signal processor or processing module that may be configured at least to: receive signaling containing information about calibrated motor speed and power data for a hydronic pumping system; and determine system pumping flow rate and pressure associated with an equivalent hydronic system characteristic variable, based at least partly on the signaling received. The signal processor or processing module may be configured to provide corresponding signaling containing information about the system pumping flow rate and pressure determined. The corresponding signaling may contain information used to control the hydronic pumping system.

Abstract: Apparatus, such as a pump controller, features a signal processor configured at least to: receive signaling containing information about a linear set point control curve based at least partly on an adaptive set point control curve related to fluid being pumped by a pump in a pumping system, and determine a control set point based at least partly on the signaling received. The signal processor may be configured to provide a control signal containing information to control the pump based on the control set point determined.

Abstract: Apparatus includes a signal processor that receives signaling containing information about real time pump operating parameters related to pumps forming part of a pumping system in a plant/facility, and a user input selecting a pump for displaying the real time pump operating parameters on a control monitor to allow a plant/facility operator to implement a centralized pump control of the pumps at a given centralized location; and that determines corresponding signaling containing information to display on the control monitor the real time pump operating parameters to allow the plant/facility operator to implement the centralized control of the pumps at the given centralized location, based upon the signaling received.

Abstract: A discrete valve flow rate converter is provided to obtain a system flow through a valve in a dynamic hydronic pumping system, e.g., based on signaling containing information about the valve's differential pressure and the valve's hydronic characteristics calibration data. The discrete valve flow rate converter resolves the valve system flow rate directly and accurately with the valve's open position and the corresponding valve differential pressure signals associated therewith. The discrete valve flow rate converter may be applied to all kinds of valves as long as their open position and differential pressure associated with is available, e.g., including implementations for control valve applications, e.g., where the valve open position is controlled automatically and accurately, as well as implementations either for pumping system pressure controls with the flow rate known, such as adaptive hydronic system pressure controls, or as an alternative to sensorless pump monitoring and control.

Abstract: A switch assembly features an automatic switch and an electronic circuit board. The automatic switch has a common contact and a normally open switch contact to short when a boiler has sufficient water, and has the common contact and a normally closed switch contact to short when the boiler has a low water level. The electronic circuit board has a signal processor, a reset switch, and a low water status LED for providing a status indication of a low water condition that remains ON even if the water level has risen unless the reset switch is reset. The signal processor couples to the common contact, the normally closed switch contact and the normally open switch contact, senses signaling containing the status of the common contact, the normally closed switch contact and the normally open switch contact, provides corresponding signaling to turn ON the low water status LED when the water level is low, and responds to a reset switch signal and turn OFF the low water status LED.

Abstract: A low water cutoff switch controller features a dual inline package (DIP) in combination with low water cutoff switch processor. The dual inline package (DIP) has DIP switches, each DIP switch configured to set in a respective application type or mode corresponding to a particular water heater model for the low water cutoff switch controller to control, and also configured to provide DIP switch signaling containing information about a respective DIP switch set. The low water cutoff switch processor is configured to respond to the DIP switch signaling, and also configured to respond to corresponding signaling containing information about a sensed water level contained in the particular water heater model being controlled by the low water cutoff switch controller, and provide control signaling containing information to control the operation of the particular water heater model. The low water cutoff switch controller is a single controller that can be used for controlling any one of a plurality of different water heater models and have different voltage applications by setting a respective one of the DIP switches.
