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: Apparatus features a signal processor or processing module configured to respond to signaling containing information about a set point and a speed related to one or more pumps in a pump system, e.g., including a variable speed multiple pump booster system, operating at a substantially constant discharge pressure; and determine an adjustment to the set point to compensate for system friction loss and maintain the substantially constant discharge pressure of the variable speed multiple pump booster system for flow variation, based at least partly on the signaling received. The signal processor or processing module 10a provides corresponding signaling containing information to control the one or more pumps in the variable speed multiple pump booster system.

Abstract: The present invention provides apparatus that features a signal processor or processing module configured to receive signaling containing information about an adaptive or self-calibrating set point control curve and a varying equivalent system characteristic curve based at least partly on an instant pump pressure and a flow rate using an adaptive moving average filter, and equivalent hydronic system characteristics associated with the instant pump pressure and the flow rate to corresponding motor power and speed reconstructed and remapped using a discrete numerical approach; and determine an adaptive pressure set point, based at least partly on the signaling received.

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: A technique for determining a boiler water condition includes a boiler controller (aka PSE unit) having a signal processor that implements a boiler control algorithm to receive signaling containing information about sets of N consecutive probe data samples related to a boiler water condition; determine stable average signaling containing information about a stable average by averaging a set of N consecutive probe data samples in the signaling received; determine present stable average signaling containing information about a present stable average by averaging a present set of N consecutive probe data samples in the signaling received; and determine corresponding signaling containing information about the boiler water condition, based upon whether the present stable average is within an allowable limit and a comparison of the present and previous stable average signaling determined.

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.

The signal processor or processing module is configured to provide the corresponding signaling containing information about whether the pump should remain in the NFSD state or the NFI state.

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.
