4. Product description
Brief description
The automatic exhaust valve is an exhaust air device control-
led by an electric external power supply. It is normally closed
or only slightly open to enable a basic volume flow rate. Air is
only extracted at a higher operating volume flow rate when the
corresponding switch contact is closed.
Special features of the ATVC-100
- Heating energy can be saved thanks to targeted ventilation
(basic volume flow rate/operating volume flow rate).
- No high volume flow rate during brief occupation of the
room thanks to the installed start delay.
- Silent opening and closing of exhaust valve.
- Exhaust valve and electro-thermal drive made from proven
components.
- Easy assembly.
- Taking the diversity factor into account,
a smaller roof fan and riser duct
can be selected.
- The exhaust valve can be closed tightly.
- Connection to the normal lighting network 230V 50Hz wit-
hout
additional delay relay (follow-up ventilation) or transformers.
How it works
When the circuit is closed, the electro-thermal drive heats up
and causes the valve disc to open within 2 to 4 minutes (delay
during brief occupation of the room). Air is exhausted through
the opening between the valve housing and the valve disc.
The valve stroke (6 mm) is always the same, i.e. the valve disc
always moves from the minimum setting to the maximum valve
opening. In the minimum setting, the exhaust valve can either
be closed or opened. Since the valve stroke is always the
same, the operating volume flow rate cannot be freely selected,
but is dependent on the minimum setting. The exhaust valve
stays open at the maximum valve stroke for as long as the
circuit is closed. Once the circuit has been interrupted, the
automatic exhaust valve remains open for follow-up ventilati-
on for approx. 5-8 minutes before it starts to move back to its
minimum setting slowly and silently.

6. Installation / commissioning
Device selection
The exhaust valve is determined by the following data:
- Stat. pressure loss ps(Pa)
- Basic volume flow rate (m3/h)
- Operating volume flow rate (m3/h)
Using this data, the stat. pressure loss and only one of the two
volume flow rates can each be freely selected.
The performance diagram (see below) is used to determine the
following:
- Number of rotations
- Residual volume flow rate
- Acoustic data.
Note that, if the minimum setting is selected, then the corre-
sponding operating volume curve must be taken into account.
Performance diagram
Example (as plotted)
Given:
- Stat. pressure drop ps= 40 Pa
- Operating volume flow rate V = 80 m3/h
Solution:
- Rotations for minimum setting 1
- Basic volume flow rate: Vo = 10 m3/h
- Sound power level for:
Basic volume flow rate <25 dB(A)
Operating volume flow rate approx. 38 dB(A)

Setting the basic air volume ow rate V0
The automatic exhaust valve is delivered ex-works in a closed
condition (basic volume flow rate V0 = m3/h). If a basic volume
flow rate is required, this must be set as follows:
1 Valve casing
2 Valve disc
3 Electro-thermal actuator
4 Tappet
5 Knurled nut
Place the exhaust valve on a firm base as shown, e.g. on a
table, and loosen the brass knurled nut "5" by turning it one
rotation in a clockwise direction.
Hold the exhaust valve at the electric drive as shown and, using
one finger of your free hand, open the valve disc "2" by turning
it the required number of rotations in an anticlockwise direction.
Place the exhaust valve on a firm base as shown, e.g. a table,
hold it firmly with one hand against the base and tighten the
knurled screw "5" in an anticlockwise direction up to the tappet
"4".
Note: It is important that the valve disc does not rotate during
this operation.
The exhaust valve is now set.

Assembly
Once the required volume flow rate has been set and the
electric connection has been completed, the automatic exhaust
valve can be inserted into the appropriate opening so that the
casing is flush with the wall. The exhaust valve is held in the
opening by 3 spring elements.
Initial commissioning
Before you start commissioning:
- Check that the air terminal devices are seated correctly.
- Remove protective film.
- Ensure that all air terminal devices are clean and free from
residues and foreign matter.
- Check that electrical connections (if any) have
been correctly made.
- Check that the fixing and connection -
with the air duct is correct.
Volume ow rate balancing
When several diffusers are connected to just one volume flow
controller, it may be necessary to balance the volume flow
rates.
