It operates using an internal heating element that senses outlet conditions and adjusts the proportion of incoming flows to maintain a stable setpoint. In HVAC systems, it is used in boiler and water heater setups to ensure safe and consistent water temperature. It is typically connected at the water distribution point and supports system safety, improved comfort, and consistent thermal control.
