Installation and operating instructions
Hygrostat (optional)
Figure 7: Front view of hygrostat
The hygrostat is a two-position controller for detecting and controlling the relative humidity
indoors. The measuring element is a hygroscopic fabric tape which undergoes a measurable
change in length via absorption of water. A micro-switch converts the changes into ON/OFF
signals.
The range of relative humidity (RH) can be continuously adjusted between 35% and 95% via a
set-point rotary control on the hygrostat's casing.

Functions
The aV100 extract air system is used for removing spent air from a room.
The Avio N 100 (N = run-on function) extractor fan is used in the aV100 extract air system. The
aV100 extract air system operates without heat recovery and runs on alternating current.
The Avio N 100 has a run-on function. Optionally, a hygrostat can be connected to control the
fan depending on the relative air humidity.
The run-on time determines how long the fan continues to run after switch-off. With activation
of the run-on time (switch-off is via a control element), the Avio N 100 continues to run until
the end of the set run-on time and then turns off automatically. This ensures an optimal air
exchange.
The run-on time is factory set at 15 minutes. It can be altered via the integrated potentiometer
within a range of 5 – 30 minutes.
The Avio N 100 extractor fan can be combined with an existing light switch or operated sepa-
rately via a switch/pushbutton.

Combination with a light switch:
The Avio N 100 is switched on simultaneously with the activation of the room lighting. When
the room lighting is switched off, the run-on time is activated; the extractor fan runs until the
end of the run-on time and then switches itself off.
