Basic Ventilation Time Functions Regulated Ventilation
* The time functions Interval operation and Run-on time are always carried out at the set regulated ventilation level (DIP switches
6 and 7).
The characteristic curve of the level 60 m³/h is part of the DIBt approval Z-51.1-215 and can be taken from it. The characteristic
curve is also summarized with all other characteristic curves in a separate document that can be downloaded from
www.lunos.de.
The fans of the Silvento ec series can be configured in combination with the circuit boards listed above and the volume flow can
be calibrated. Instructions can also be found at www.lunos.de.
The volume flows specified in the accompanying documents refer to the installed condition, taking into account correct design/
planning and corresponding installation.

Additional installations and electrical components in the ventilation unit are not permitted!
Connection diagrams for further fan functions available on request!
Caution! Any installation work on the ventilation unit may only be carried out with the mains
voltage disconnected! The ventilation unit is insulated in accordance with protection class II, a
protective conductor connection is not required.
Make sure all connection lines are de-energized before connecting the ventilation unit to the
power supply! (Disconnection from power supply with at least 3 mm contact opening, e.g.
fuse)
Each circuit connected to the ventilation system must be fitted with residual current protection
(e.g. RCD switch)!
Electrical connections must be carried out by qualified staff only!
6.1 Automatic operation with humidity control according to DIP switch position of the
control board.
Comfort control: Humidity controlled operation
Basic control: Interval switching possible
6.2 With remote control (0 - 10 V)
The remote control input is divided into two ranges. In the range of 0-5 V the level is
set absolutely, i.e. with highest priority (corresponds to DIP 6,7 with switched L1 ). In the
range of 6-10 V only the base load is set (corresponds to DIP 1,2). In the range of
0-0.4 V the fan operates autonomously.
6.3 Depending on the control board, DIP switch position and module:
With run-on time (basic control): Deactivation of the run-on functions (L2), conti-
nuous operation basic ventilation or OFF according to DIP switches 1 and 2 swit-
chable to regulated ventilation (L1) according to DIP switches 6 and 7
With humidity control (comfort control): Humidity control can be deactivated (L2),
switchable to regulated ventilation (L1)
Note: No light coupling possible with VDE-compliant installation
((R) Bridge)
6.4 Depending on control board, DIP switch position and module:
Single-stage operation, switchable to regulated ventilation
Continuous operation basic ventilation and run-on time-controlled regulated ventila-
tion
Humidity control, switchable to regulated ventilation
Run-on time-controlled regulated ventilation
Note: Use a two-pole switch to switch the room lighting simultaneously with the
regulated ventilation!

3. Reassemble in reverse order
The following DIP switch positions with the following functions are available:
Using DIP switches 1, 2, 6 and 7, you can set the air volume flows for basic and regulated ventilation,
and DIP switches 3, 4 and 5 can be used to configure the delay time functions.

Fans equipped with the comfort board 5/EC-FK have an independent humidity control with a stan-
dard control range of 50 - 70 % r.h. controlling between the set basic ventilation stage (DIP switches
1, 2) and the regulated ventilation stage (DIP switches 6, 7). This ensures that the exhaust air volu-
me flow is constantly adjusted to the room air humidity and room temperature, thus achieving an
optimum level of comfort. There is only as much ventilation as necessary, but also only as little as
possible, which saves energy, prevents over-humidification of the apartment and avoids structural
damage and mould.
The control is carried out in a virtually stageless and "intelligent" manner, differentiating between
permanently high relative humidity or rapid increase (e.g. due to showers).
If the relative humidity cannot be significantly reduced within a period of two hours (e.g. in summer),
the fan will be switched to basic ventilation mode.
If the relative humidity increases by more than 5% within one hour during reduced operation mode,
the reduced operation mode will be terminated. If the relative humidity falls below the lower switching
threshold and the basic ventilation level is set to OFF, the fan will be switched off.
If the fan is set to the basic ventilation level OFF, it will run once per hour for 3 minutes at the level of
15 m³/h (sniff mode). If a relative humidity above the set switching threshold, e.g. 50 % RH at 22°C,
is measured during this time, humidity control will be activated.
If the measured relative humidity is lower than the switching threshold, the fan will be switched off
again after these three minutes.
Notes:
 If voltage is applied to L2, all special functions, switch-on delay, run-on time, interval operation and
humidity control (5/EC-FK only) will be deactivated.
 Within the first two hours after connection to the mains, the fan runs at the level corresponding to
the relative humidity value currently measured .

7.1 The LED lights up continuously when the filter is dirty.
Remove the front cover, remove the filter. Insert a new or cleaned filter. The filter can be
cleaned e.g. using a dishwasher.
Press the button (S) with a tool, e.g. a pen, for 3 seconds; the LED goes out.
Put the front cover back in place.
Never operate the unit without a filter!
When necessary, wipe the front cover and grille frame using a dry soft cloth.
Filter change and cleaning must not be carried out by children or persons who are not able to
operate the unit safely on account of their physical, sensory or mental capacity or due to their
inexperience or lack of skills.
