BRIEF DESCRIPTION

The unit described herein is an axial fan for exhaust ventilation of small to medium-sized premises heated during winter.

The fan is made of white plastic. The fan design can also include a backdraft damper to prevent back ﬂow when the fan is

switched oﬀ. The fan ﬁts 100 mm air ducts.

OPERATION GUIDELINES

The fan is rated for connection to single-phase AC 230 V/50 Hz or 230 V/60 Hz power mains. Air motion direction in the

system must match the pointer on the fan casing.

Ingress protection rating against access to hazardous parts and water ingress is IP45.

The fan is rated for operation at the ambient temperature ranging from +1 °C up to +45 °C.

The unit is rated as a Class II electrical appliance.

INSTALLATION AND SETUP

The fan is designed for wall or ceiling mounting with direct air exhaust to the ventilation shaft or into the round air duct of

matching diameter (Fig. 2).

Fan installation sequence:

Step 1. Cut oﬀ power supply and make sure electricity has been turned oﬀ (Fig. 4).

Step 2. Run the power cable to the vent hole (Fig. 5).

Step 3. Remove the front panel from the fan. Then remove the terminal block cover (Fig. 6).

Step 4. Mark and drill holes for mounting the fan and then install the fan (Fig. 7-9).

Step 5. Connect the fan to power mains according to the wiring diagram (Fig. 13-16).

Step 6. Install the terminal block cover (Fig. 10) and the front panel on the fan casing (Fig. 11).

Step 7. Supply power voltage to the fan (Fig. 12).

FAN SETUP

on — interval timer turning on and adjustment is performed with the potentiometer Ton. To turn the interval timer oﬀ

set the potentiometer Ton into the leftmost position. Rotation of the potentiometer for 1/3 clockwise sets the interval timer

operation for 6 hours, rotation of the potentiometer for 2/3 clockwise sets the interval timer operation for 12 hours, and

rotation of the potentiometer clockwise in the rightmost position sets the interval timer operation for 24 hours.

oﬀ — To adjust the fan turn-oﬀ delay time, turn the control knob To clockwise to increase and counter-clockwise to

decrease the turn-oﬀ delay time respectively, adjustable from 2 up to 30 minutes.

— To adjust the humidity set point turn the control knob H clockwise to increase and counter-clockwise to decrease the

humidity sensor set point, adjustable from 60 % up to 90 %.

WARNING! If the switch is turned o or the indoor humidity falls below the set point within 60 seconds after

activation of the switch or the humidity sensor, the fan continues operation at low speed.

Terminal designations on wiring diagrams:

L — phase

N — 0

S — external switch

QF — automatic circuit breaker

CAUTION! The fans rated for 12 V power voltage (stated on the packing box and on the fan casing) connect to

12 V power mains only!

DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT

OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD.

the turn-on and turn-oﬀ delay time and the humidity set

point.

ELECTRONICS OPERATION ALGORITHM

The fan with the timerT — the fan is started after actuation of the external switch, e.g. the light switch. The control voltage

is supplied to the input terminal LT (ST). After the control voltage is oﬀ the fan continues to operate within the set time

period adjustable from 2 to 30 minutes by the timer.

The VT model is turned on and oﬀ by the pull-cord switch.

The fan with the timer T1 — after turning on the switch, for example, a light switch, the fan is switched on in a set turn-on

delay time period, adjustable from 0 to 2 minutes. After the switch is turned oﬀ the fan keeps operating for a set turn-oﬀ

delay time period, adjustable from 2 to 30 minutes.

The fan with the timer and the humidity sensor TH — the fan starts after the control voltage is supplied to the input

terminal S or if indoor humidity level Hexceeds the set point adjustable from ~60 % to ~90 %. After the control voltage is oﬀ

or the humidity level has decreased the fan will keep running within the time set by the timer ranging from 2 to 30 minutes.

To set the maximum humidity setpoint 90 % set the potentiometer to H max position.

To adjust the fan turn-on delay time, turn the control knob T clockwise to increase and counter-clockwise to decrease the

turn-on delay time respectively. To adjust the humidity set point turn the control knob Hclockwise to increase and counter-

clockwise to decrease the humidity sensor set point.

CAUTION!The timer circuit is live! 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 it to change

the turn-on and turn-o delay time and the humidity set point.

DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT

OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD.
