OPERATION RULES
The fan is designed for connection to single phase AC 220...240 V / 50 Hz power mains and is rated for continuous
operation always connected to power mains.
Air flow direction in the system must match the pointer in the fan casing.
The fan is rated for operation at the ambient temperature ranging from +1°C до +45°C.
The fan is double insulated and requires no grounding.
The fan complies with the requirements according to the EU norms and directives, to the relevant EU Low Voltage
Equipment Directives, EU Directives on Electromagnetic Compatibility.
We hereby declare that the following product complies with the essential protection requirements of Electromagnetic
Council Directive 2004/108/EC, 89/336/EEC and Low Voltage Directive 2006/95/EC, 73/23/EEC and CE marking
Directive 93/68/EEC on the approximation of the laws of the Member States relating to electromagnetic compatibility.
This certificate is issued following test carried out on samples of the product referred to above.
Assessment of compliance of the product with the requirements relating to electromagnetic compatibility was based
on the following standards
ELECTRONICS CONTROL LOGIC
The fan with timer is turned on after control voltage is supplied to the input terminal LT by the external switch, i.e.
light switch. After the control voltage is off the fan continues to operate within the set time period adjusted from 2 to 30 minutes.
The VT model is switched on/off with a pull cord switch.
The fan with timer and humidity sensor is turned on after control voltage is supplied to the input terminal LT or in case
of exceeding the humidity threshold value regulated from ~60% до ~90%. After the control voltage is off or if the humidity
threshold value H drops the fan continues to operate within the set time period adjusted from 2 to 30 minutes.
To adjust the turn off delay time rotate the potentiometer T control knob clockwise to increase and counter clockwise to
decrease the turn off delay time. To adjust the humidity threshold value turn the potentiometer H control knob clockwise
to increase and counter clockwise to decrease the humidity threshold value respectively (fig. 13).
To adjust the maximum humidity threshold rotate the control knob of the potentiometer H to H max position.
The fan with timer and motion sensor s turned on after registration of motion in the distance from 1 to 4 m from the
motion sensor with the horizontal viewing angle 100°. After no motion is registered more, the fan the fan continues to
operate within the set time period adjusted from 2 to 30 minutes. To adjust the humidity threshold value turn the
potentiometer H control knob clockwise to increase and counter clockwise to decrease the humidity threshold value
respectively (fig. 13).
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 alter the turn off delay time or the
humidity threshold. Do not use a metal screwdriver, knife, etc. for adjustment operations not to damage the circuit board.
