Energy Efficient Products

Which energy efficiency class is to be indicated; the one for medium temperature applications or for low temperature applications?

According to the regulations, a reference to the seasonal space heating energy efficiency class under average climate conditions for that model shall be included in advertisement and technical promotional material. 

Since the medium temperature applications is the most common one, it is the intention of the legislation that for this application the energy class should be displayed in advertisements and technical promotional material. Also both classes may be indicated if it is clearly indicated which class belongs to which temperature application.
