Heating demo

This on-line visualization project enables you to clearly display real-time data of the heating process in the building of the GEOVAP company. The main visualization window consists of three parts – the boiler room, spaces to heat, and exterior spaces. The boiler room is controlled by a Tecomat NS 946 PLC which provides data to the Reliance system. The building is heated in winter only.



Starting the demo

By clicking on the Desktop Demo button (file with a .jnpl extension), the program files are automatically downloaded to the computer. When you run this file (manually or automatically), the visualization project is opened in the Web client's standalone window.


By clicking on the Mobile Demo button, the visualization project is automatically run in a new window of your smartphone's or tablet's Web browser. You can also use a QR code reader to run the mobile demo.


By clicking on the Reliance Server button, Reliance Server's Web page is opened in a new window of the Web browser.

Description of the visualized process

The main visualization window clearly displays how the building of the GEOVAP company is heated. It consists of three parts – the boiler room, spaces to heat, and exterior spaces. The boiler room is controlled by a Tecomat NS 946 PLC which provides data to the Reliance system.


The Boiler Room visualization window displays three gas boilers, boiler pumps, and circulator pumps. The temperatures of the boiler circuit's backflow water and outlet water are measured by temperature sensors. Preheated water from the boiler circuit flows into the west and east side hot water pipes and heats individual rooms where the water temperature is also measured by temperature sensors. In addition, there are two temperature sensors attached to the west side and east side of the building to measure the outside temperature.


By clicking on the Process button, the description of the boiler room processes can be displayed.


If you click on the Temp. Trends button, three real-time trends will be displayed. These trends represent the temperature of:


  • outlet water in the boiler circuit
  • inlet water flowing into the west and east side hot water pipes
  • temperature of outside air
