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.
After the relative humidity has fallen to the setpoint,
