Environmental conditions and operating limits

• Permissible maximum temperature of air medium + 40 °C.
• The air supply to the home must be set up so that virtually no air can flow into the living areas from the kitchen, bathroom or WC.
• A room from which the air is to be extracted must be fitted with a non-closable, free supply air cross section of at least 150 cm², e.g. with MLK door ventilation grille.
• ER EC/ER EC 2.1 units have resistance to interference in line with EN 55014-2 (depending on pulse type and an energy component of 1000 to 4000 V). These values can be exceeded when operating with fluorescent tubes. In this case, additional interference suppression measures (L, C or RC modules, protection diodes, varistors) are required.
