Water Heater Control Using External Temperature Sensor

摘要

A system and method for controlling a water heater that operates according to a voltage supply includes a temperature sensor, mounted on at least one of a temperature and pressure (T&P) valve of the water heater and a hot water line of the water heater, that generates a temperature signal corresponding to a first temperature of the at least one of the T&P valve and the hot water line. A control module mounted on the water heater includes a switching module that receives the voltage supply and outputs the voltage supply to the water heater. The voltage supply passes at least one of through and adjacent to the control module. The control module determines a second temperature of water within the water heater based on the temperature signal and selectively actuates the switching module to turn on and turn off the voltage supply to the water heater based on the second temperature.

1. A method for controlling a water heater that operates according to a voltage supply, the method comprising:
mounting a temperature sensor on at least one of a temperature and pressure (T&P) valve of the water heater and a hot water line of the water heater; generating a temperature signal corresponding to a first temperature of the at least one of the T&P valve and the hot water line; mounting a control module on the water heater, the control module including a switching module that receives the voltage supply and outputs the voltage supply to the water heater, wherein the voltage supply passes at least one of through and adjacent to the control module; and using the control module,
determining a second temperature of water within the water heater based on the temperature signal, andselectively actuating the switching module to turn on and turn off the voltage supply to the water heater based on the second temperature.
