This ventilator has been developed for continuous operation to ensure the
necessary basic ventilation in buildings. Boost ventilation can be activated
manually (this requires a second, switched „L1“ phase) or via a humidity
sensor (a permanent „L“ phase is sufficient here) as needed.
Please read these installation instructions completely before starting work.
Caution
Ensure that all electric power is turned off before carrying out any work. The
electrical connections may only be conducted by a suitably qualified person
and must comply with the locally applicable regulations. If a fireplace with
chimney is used, care must be taken that sufficient air can enter the room being
ventilated.

Use the control panel to start-up and adjust the ventilator.
As soon as the ventilator is reconnected to the power supply, the two
buttons flash (12.1) and (12.2) for max. 15 minutes.
If you now press, for example, the button (12.1), the factory setting
„Boost ventilation/small bathroom“ is activated and flashes (12.4).
Set the house switch for manual boost ventilation to OFF (no power to „L1“) and
switch the main circuit breaker back on.

Remove the cover by turning counterclockwise, loosen the 3 holding
screws and carefully open the cover with the control panel.
Install an air duct with internal diameter of 100 mm in the wall or
ceiling. For wall installation make sure the duct runs to the outside with
a slight gradient. For ceiling installation you must insulate the air duct if
it passes through unheated areas.
The power cable should be sited with a spacing of X = 65 mm from the
centre of the air duct. You will need a switched „L1“ phase in addition
to the continuous „L“ phase for manual activation of the „boost ventila-
tion“ function.
Feed the power cable through the provided opening (A) and screw the
unit to the wall or ceiling with four screws. Ensure 2 positioning arrows
are pointing upwards when installing in wall application.
Strip the cable as shown in (B) and connect according to the circuit
diagram. The ventilator is double insulated and does not require a
protective earth conductor. If the house has an earth conductor, this
can be „parked“ at the terminal (C). Secure the connected cable with
the cord grip (D).
Then reclose the cover with the control panel and screw it down.
Attach a safety guard to the air duct outlet on the outside.
