초록 ▼

A water heater controller including hot water supply temperature sensor, a return water temperature sensor, a cold water flow sensor, a recirculation loop ambient temperature sensor, and a processor and control unit for controlling the heating of water and the circulation of water. The processor and control unit controlling the water heater to permit the hot water supply temperature to decrease to within a first supply setback temperature range defined by a calculated first setback temperature during non-use of hot water that is within a historically indicated hot water use period, (2) selectively controlling the water heater and recirculation apparatus to permit the hot water supply temperature to decrease to within a second supply setback temperature range defined by a second setback temperature and to permit the return water temperature to decrease to within a return setback temperature range during hot water non-use that is within a historically indicated hot water non-use period, and (3) controlling the water heater and recirculating means during hot water use so that the hot water supply temperature is controlled relative to a predetermined maximum temperature. The first setback temperature is calculated relative to system heat loss and a minimum return water temperature.

대표청구항 ▼

A controller for a hot water heater system having a heater for heating water, a hot water outlet for supplying hot water, a cold water inlet for receiving cold water, and a return line for returning non-used supplied hot water for reheating, the controller comprising: recirculating means for circulating the supplied hot water to points of usage and back to the heater via the return line; means coupled to the hot water outlet for sensing the temperature of the hot water supply and providing hot water supply temperature data; means coupled to the return line for sensing the temperature of the return water and providing return water temperature data; means for sensing use and non-use of hot water; means for storing historical data indicative of time periods of hot water use and non-use; and control means responsive to said hot water supply temperature sensing means, said return temperature sensing means, and said use sensing means for (a) calculating a first setback temperature, (b) controlling the heater to permit the hot water supply temperature to decease to and remain within a first supply setback temperature range based on said calculated setback temperature during sensed non-use that is within a historically indicated hot water use period based on said historical use and non-use data, (c) selectively controlling the heater and said recirculating means to permit the hot water supply temperature to decrease to and remain within a second supply setback temperature range based on a second setback temperature that is lower than said first setback temperature and to permit the return water temperature to decrease to within a return setback temperature range based on said second setback temperature during non-use that occurs within a historically indicate non-use period based on said historical non-use data, (d) controlling the water heater and said recirculating means during sensed use of hot water so that the hot water supply temperature is controlled relative to a predetermined maximum temperature which is greater than said first setback temperature.
