Abstract

A method for operating a multi-family/commercial plumbing system includes sensing an event and recording for each sensed event at least one parameter selected from the group consisting of date, day of the week, start time, duration of the event, water flow, water temperature, and humidity. The parameters are analyzed to determine a pattern and thereafter water flow, circulation, water temperature, and water use are controlled in accordance with the determined pattern.

Claims

1. Method for operating a multi family/commercial plumbing system, the method comprising:

sensing an event, said event comprising at least one of a group consisting of measurement of water temperature in water flow between a storage tank and boiler;

measurement of water flow in and out of said boiler;

detection of water leaking in hot and cold water lines, measurement of water temperature in hot water flow from a hot water heater;

measurement of moisture in walls and floors;

detection of activation of dampers;

measurement of room temperature in each of a plurality of rooms;

detection of operation of a water circulating pump;

recording for each sensed events at least one parameter selected from a group consisting of date, day of the week, start time, duration of the event, water flow, with temperature and humidity;

analyzing the searched parameters to determine patters; and

controlling water flow, circulation, water temperature, and water use in accordance with the determined pattern.

2. The method according to claim 1 further comprises reiterating the steps of sensing, recording, analyzing, and activating.

3. The method according to claim 1 further comprising analyzing the determined patterns for potential problems and reporting therein.

4. The method according to claim 3 wherein the potential problem is excessive running of the pump.

5. The method according to claim 3 wherein the potential problem is a non-seasonal change in a relationship between hot and cold water use.

6. The method according to claim 2 further comprising analyzing the determined patterns for potential problems and reporting therein.

7. The method according to claim 6 wherein the potential problem is excessive running of the pump.

8. The method according to claim 7 wherein the potential problem is a non-seasonal change in a relationship between hot and cold water use.
