Yes. Regulation (EU) 2024/1103 regulates the placing on the market of separate related controls, namely controls intended to be used with local space heaters in scope of this Regulation but placed on the market separately. Manufacturers are allowed to place on the market local space heaters without control and claim the corresponding correction factors making the product compliant with the Ecodesign requirements.
However, the product has to be equipped with all necessary components to be able to use these function(s). Offering these functions only as options to be purchased separately and installed by the customer is not sufficient for applying those correction factors.
