Input settings
The ventilation unit has three inputs: one analog and two digital inputs. The functions listed in the table below can be selected for these inputs. Digital control can be operated using either a press button or a rocker switch. Both digital inputs recognize the type of the switch automatically.
Possible uses of the analog and digital outlets include boost requests coming from the cooker hood or the central vacuum cleaner, and a button located next to the fireplace that can be used to turn the Fireplace mode on or off.
Press button functions are activated when the button is in the up position. The press button function can be cancelled by pressing the button for five seconds. The operation of the rocker switch, on the other hand, is based on the status of the switch. When the switch is in the ON position, the function is activated. When the switch is in the OFF position, the function is deactivated. The rocker switch function can be cancelled by pressing the switch for five seconds.
When the rocker switch is turned to the ON position for the first time, the rocker switch function is activated after five seconds. After that, the function will always be activated immediately.
The press button function can also be activated by keeping the rocker switch in the ON position for less than five seconds. The press button function can be cancelled by keeping the rocker switch in the ON position for over five seconds.
The latest change made from any user interface will remain valid.
The settings of three inputs can be edited from the Input settings menu.
