Compliance and transparency made simple.
The Danish Safety Technology Authority has introduced stricter requirements for consumer information about heat distribution meters. The new executive order replaces the previous control system with a mandatory control manual. As a landlord, administrator, or housing association, you must therefore provide residents with access to detailed information—from radiator brand and size to scale factors and meter types.
With ista's digital control manual, all necessary information is gathered online. This ensures that data is always accurate, up to date, and fully compliant with legislation.
The smart shortcut to full compliance.

Full compliance without the administrative burden.
We take care of the practicalities so that you don't have to keep track of which, or when, meters need checking. All meters are checked at an accredited metrology institute and replaced if necessary.
The checks are carried out in full compliance with legislation, including the Danish Safety Technology Authority's regulations on metrological control of heat consumption meters. The result is that your meters always comply with current legal requirements.
Good to know: Consumer protection is guaranteed by law. Therefore, control systems and control manuals remain mandatory for both non-rotary water meters (cold and hot water) and heat energy meters, regardless of the replacement method.
