power mains.
The fan is designed for continuous operation always connected
to power mains.
Air flow direction in the system must match the pointer direction
on the fan casing.

The fan is rated for operation at the ambient temperature rang-
ing from +1 °C up to +45 °C.
The fan requires no grounding.

WARNING!
The timer circuit is under mains voltage. Disconnect the fan
from power mains prior to any adjustment operations. The fan
delivery set includes a specially designed plastic screwdriver
for fan settings adjustments. Use the screwdriver to change the
turn-off delay time or the humidity set point (Fig.3.3).
Do not use a metal screwdriver, knife, etc. for adjustment opera-
tions not to damage the circuit board.
Electronic operating logic
Fan is equipped with an electronic processor (ТН) with perma-
nent humidity level monitoring function that prevents conden-
sate generation. The fan switches automatically on as the rela-
tive humidity in the premise reaches the preset set point value
adjustable from 60 to 90% and continues operating within 2 to
30 minutes according to the timer setting until the humidity level
will not reach set point.
To adjust the humidity set point turn the control knob of H regu-
lator clockwise to increase the humidity sensor set point and
counterclockwise to decrease it (Fig.3.3).
The fan may operate in timer mode if it is connected to power
mains through the light switch. After the light is off the fan oper-
ates within the set time period, from 2 to 30 minutes.
To adjust the turn-on delay time turn the control knob of the
regulator clockwise to increase the set point and counterclock-
wise to decrease it (Fig.3.3).
Maintenance
The fan maintenance periodicity is at least once per 6 months.
Maintenance sequence is shown in Fig.4.
WARNING!
Avoid water dripping on the electric components.
