Water preconditioner system

A water preconditioner system comprising:

• a user interface for manually or automatically receiving inputs from the user;
• a mixing assembly connected between hot and cold water supply lines, the mixing assembly including a first control valve coupled to the hot water supply line and a second control valve coupled to the cold water supply line, with each of said first and second control valves operable in a closed position and an open position and in at least one partially open position defined between the closed and open position;
• and
• a controller in communication with the plurality of control valves and the user interface for controlling the operation of the system, wherein the controller is configured to:
• receive a first user input from the user interface indicative of a desired preset water dispensing temperature of water flowing through the mixing assembly;
• determine a water temperature of water flowing through the mixing assembly;
• operate in a first mode in response to the first user input from the user interface to heat the water flowing through the mixing assembly from the determined water temperature to a target temperature when the determined water temperature is less than the desired preset water dispensing temperature, the target temperature being less than the desired preset water dispensing temperature by a predetermined number of degrees;
• operate in a second mode in response to the first user input from the user interface to heat the water flowing through the mixing assembly from the target temperature to the desired preset water dispensing temperature;
• operate in a third mode in response to the first user input from the user interface to precool the water flowing through the mixing assembly from the determined water temperature to a target temperature when the determined water temperature is greater than the desired preset water dispensing temperature;
• operate in a maintain mode to maintain the temperature of the water flowing through the mixing assembly at the desired preset water dispensing temperature;
• and
• operate in a water dispensing mode to regulate the water flow from the mixing assembly to the user at the desired preset water dispensing temperature;
• wherein in the water dispensing mode, the controller toggles a fluid control valve in the open position to regulate the water flow from the mixing assembly to the user at the preset temperature, and
• wherein the fluid control valve is in a bypass position in the first, second, third and maintain modes to recirculate the water.
