HL 620 Domestic Heating System Control Training Panel Show data sheet (pdf file) Print page
Technical Description
The training panel clearly demonstrates the function of a heating controller. The electronic controller, room thermostat and mixer valve are real components. The water, indoor and outdoor temperatures are set using potentiometers. Lights indicate the function of the pumps and the boiler. The components are clearly laid out on the system diagram to show their relationships. The system reacts rapidly because the temperature parameters are manually set by potentiometers.
The HL 100 Universal Stand is a recommended accessory.
