HOT WATER HEATER SYSTEMS AND METHODS FOR CONTROLLING ELECTRONIC MIXING VALVES

摘要

Hot water heater systems and methods for controlling electronic mixing valves of hot water heater systems are disclosed. An electronic mixing valve provides a flow of water in a mixed output line. A method includes determining a temperature value inside a hot water tank of the hot water heater, and comparing the hot water tank temperature value to a setpoint temperature value. The method further includes comparing a temperature value for water in the mixed output line to a lower setpoint threshold value when the hot water tank temperature value is greater than the setpoint temperature value, wherein the lower setpoint threshold value is less than the setpoint temperature, and setting the electronic mixing valve to a safe position wherein the electronic mixing valve is less than fully open when the temperature value for water in the mixed output line is less than the lower setpoint threshold value.

1. A method for controlling an electronic mixing valve for a hot water heater, the electronic mixing valve providing a flow of water in a mixed output line, the method comprising:
determining a temperature value inside a hot water tank of the hot water heater; comparing the hot water tank temperature value to a setpoint temperature value; and comparing a temperature value for water in the mixed output line to a lower setpoint threshold value when the hot water tank temperature value is greater than the setpoint temperature value, wherein the lower setpoint threshold value is less than the setpoint temperature; and setting the electronic mixing valve to a safe position wherein the electronic mixing valve is less than fully open when the temperature value for water in the mixed output line is less than the lower setpoint threshold value.
