Abstract
A thermostatic valve is controlled by a motor that receives signals from an electronic control module (ECM). The ECM sends an electric signal corresponding to a desired outlet stream temperature to the motor, which turns the thermostatic valve to a location corresponding to the desired temperature. The ECM also adapts the thermostatic valve capacity to outlet flow demands by restricting and opening inlet valves, ensuring that the thermostatic valve can maintain an equilibrium temperature for both high and low outlet flow applications.
