Networked Boilers and Control Method

A control system for an appliance comprising:

• a controller;
• a first circuit for using hot-water provided by the appliance;
• the first pump system configured to pump hot-water provided by the appliance through the first circuit;
• a first valving assembly configured to selectively provide hot water to the first circuit;
• a first sensor configured to send a signal to the controller associated with a demand for hot water in the first circuit;
• a second circuit for using hot water provided by the appliance;
• a second pump system configured to pump hot-water provided by the appliance through the first circuit;
• a second valving assembly configured to selectively provide hot water to the second circuit;
• a second sensor configured to send a signal to the controller associated with a demand for hot-water in the second circuit;
• and
• a communication system configured to operatively connect the controller to the first pump system, the first valving assembly, the first sensor, the second pump system, and the second valving assembly, and the second sensor,
• wherein the controller is configured to prioritize which circuit to send hot-water to win receiving signals from both the first and second sensor requesting hot-water and control the appliance to provide hot water at either a first or second temperature.

A method of operating an appliance comprising:

• receiving a first signal from a first remote sensor;
• processing the signal to determine a need for hot water for a first circuit;
• receiving a second signal from a second remote sensor;
• and
• processing the signal to determine a need for not water for a second circuit,
• wherein the signals may either be calls for hot water at the same temperature or signals for hot water at different temperatures.
