TIMER OPERATION LOGIC
Fan with timer option switches on as control voltage is
supplied to L clamp. After voltage is off the fan continues
operating within the set time period adjustable between
2 and 30 min. The time is regulated by turning the
potentiometer T clockwise to increase and counter-clockwise
to decrease the running-out time, fig. 52.
Fan with timer and humidity sensor switches on as control
voltage is supplied to L clamp or when the humidity level
adjustable between 60% and 90% is exceeded.
After voltage is off or the humidity level H decreases the fan
continues operating within the set time period adjustable
between 2 and 30 min. The time T and humidity H values are
regulated by turning the appropriate potentiometers T and H
clockwise to increase and counter-clockwise to decrease
the running-out time and humidity level respectively.
To set the maximum humidity level set the potentiometer to
H max 90% position, fig. 52.
Warning! The timer diagram is under mains voltage.
Any regulations are allowed when the fan is disconnected
from power supply only. The fans are designed for continuous
peration with permanent power supply. Air flow direction
in the system must match the pointer direction on the fan
casing.The fans are designed for the operation temperature
0
in the range between 0 Ñ and 45 Ñ.
Store the fan in the original manufacturer's packing box
in a ventilated premise at the temperature from +5°Ñ to + 40°Ñ
and relative humidity not exceeding 80% (at +25°Ñ).
Installation, connection, adjustment and repair works shall
be performed only after the fan is disconnected from power
supply network.
Only the qualified electrical engineers authorized for
independent execution of the electrical works for the
electrical installations with the voltage up to 1000 V are
allowed for servicing and mounting after reading this manual.

device must be in compliance with the acting norms and
standards.
The fixed wiring system shall be equipped with automatic
circuit breaker.
The fan is to be connected through the switch integrated
into fixed wiring system. Keep the clearance between the
dead contacts not less than 3 mm for all poles.
Before connecting the fan to power supply network,
please make sure that the fan impeller, casing and grille
are free of any visible damages and that the casing has no
foreign objects inside that can damage the blades.
