Open fireplace mode

In apartments using controlled room ventilation, the external ventilation

equipment must often be switched to a special operating mode (open fireplace

mode) when the open fireplace is used, thus preventing underpressure and,

therefore, the risk of harmful emissions.

Open fireplace mode of the ventilation equipment can be displayed on the

central apartment unit by closing the respective input.

State whether a contact for open fireplace mode is installed and from where

the central apartment unit receives its state.
