2.6. Unpacking and checking
a) Carefully take the equipment out of the box.
b) Check the nameplate data and the type for correctness as
shown on the sticker on the box.
c) Check the equipment for damage and completeness.
d) Check whether the appliance is packed with the necessary
documentation and accessories.
2.7. Arrangements
2.7.1. Standard regulation
The BTV-ssst is the standard version with standard control only.
With this standard control, the fan starts ventilating at high speed
as soon as it is switched on and continues until it is switched off by
the (light) switch.
2.7.2. Timer control
The BTV-ssst T and BTV-ssst HT are equipped with a time switch
and are ideal for applications where post-ventilation is required,
such as in toilets. The fan is switched on via the light switch or a
separate switch and continues to run for approximately 10 minutes
after it has been switched off. The so-called follow-up time is set at
approx. 10 minutes on delivery. If required, this time can be
changed by turning the potentiometer.
2.7.3. Hygrostat and timer control
The BTV-ssst HT is equipped with a timer and a humidity control
and is ideal for applications where humidity control and post-
ventilation are required, such as in bathrooms, showers, laundry
rooms and kitchens.
Switching to high mode by the humidity control occurs
automatically if the humidity level in the room exceeds the set
value. The switching point (relative humidity) is adjustable
between 40% and 95% by means of the setting potentiometer.

the fan will continue to run at high speed for the set follow-
up time.
Upon delivery, the humidity control is set to approximately 75%.
2.7.4. Operating the fan
The BTV-ssst is operated using the light switch or a separate
switch. As soon as the switch is turned on, the fan switches on. As
soon as the switch is turned off, the fan also switches off or
continues to run temporarily, depending on the control.
2.8. Recycle
Sustainable materials have been used in the manufacture of this
product. This product must be disposed of responsibly at the end
of its life cycle. The government can provide you with information
about this.
The product packaging is recyclable. These materials must be
disposed of responsibly and in accordance with official regulations.
In order to draw attention to the obligation to separate batteries
from household electrical waste, the product bears the symbol of a
waste bin with a cross through it. This means that the product must
not be disposed of with normal household waste at the end of its
service life. The product must be taken to a specialised waste
collection centre in the municipality or to a point of sale that
provides this service.
The separate disposal of batteries and household appliances avoids
possible negative consequences for the environment and health
caused by inappropriate treatment. It ensures that the materials
that make up the appliance can be recovered to achieve significant
savings in energy and raw materials.
