Abstract

Methods and compositions for controlling and monitoring residential and commercial pumping systems. Preferably, the controlling and monitoring functions include a remotely located controller component capable of displaying alerts and/or from which a user may input commands regulating the functioning of the plumbing system. In particularly preferred examples, the plumbing system is an “on command” hot water system in which hot water availability, use and energy efficiencies and conservation are monitored and maximized.

Claims

1. A remotely located controller component for a structural on demand hot water system (HWS), said HWS comprising a hot water source, a hot water delivery line, a hot water return line, one or more sensors, a local controller and a hot water circulation pump;

comprising;

said local controller component comprising at least one input component for receiving sensor signals, and at least one output component for sending control signals,

at least one said one or more sensors comprising at least one temperature sensor detecting water temperature at said hot water delivery line and/or said hot water return line;

said local controller component being structured to receive temperature-dependent data from said at least one temperature sensor, and export a control signal to one or more HWS components if the difference in water temperature between the delivered hot water and the water in the hot water return line exceeds and/or falls within a predetermined value;

wherein said remotely located controller component receives sensor signals from, and/or sends control signals to, said local controller component wirelessly, and contains software instructions installed therein to calculate and display energy usage data and water usage data related to the structural on demand hot water system to the user upon command.

2. The remotely located controller component of claim 1 structured to receive sensor signals from, and/or send control signals to, the HWS via the internet.

3. The remotely located controller component of claim 2, structured to receive status data signals from the HWS.

4. The remotely located controller component of claim 2, structured to receive alert data signals from a local controller component of the HWS.

5. The remotely located controller component of claim 4, structured to receive alert data signals from a local controller component of the HWS comprising information selected from the group consisting of image, video, energy usage, water usage, and video feed data to the user.

6. The remotely located controller component of claim 1 structured to receive sensor signals from, and/or send control signals to, the local controller via the internet using at least in part a method selected from the group consisting of wifi, Bluetooth®

, satellite, and a cellular telephone network.

7. The remotely located controller component of claim 6 wherein the remote controller component is structured to receive sensor signals from and/or send control signals to one or more device selected from the group consisting of:

an alarm system, a refrigerator, an air conditioner, a heating system, a door lock, and structural lighting.

8. The remotely located controller component of claim 1 wherein said one or more HWS components are selected from the group consisting of a water flow sensor, a water line pressure sensor, a manual valve, an automated valve, a water temperature sensor, a pump status sensor, a local controller, a sound detector, a camera, a video camera, a pump flow rate sensor, a hot water source status sensor, a hot water source thermostat, a moisture detector, a time of day indicator, a day of week indicator, and a timer status detector.

9. The remotely located controller component of claim 1 structured to accept user input and transmit a control signal based thereon directly or indirectly to said one or more HWS component.

10. The remotely located controller component of claim 1 structured to receive sensor signals from said local controller component indicating an event selected from the group consisting of a loss of water pressure, a loss of water flow, or a lack of hot water in the hot water line and, if such event is detected, to send control signals to said local controller component to cause the pump to turn on for a predetermined circulation time period.

11. The remotely located controller component of claim 1, structured to determine patterns of pump activity, water presence or flow, water pressure, temperature, period of pump activity or inactivity, period of hot water source activity or inactivity.

12. The remotely controlled component of claim 1 comprising a software application configured to wirelessly transmit sensor data from said local controller component and/or control signals to said local controller component.
