4.0 Electrical connection
All work must be carried out with the equipment fully isolated from the power supply. The electrical connection
is to be carried out in accordance with the relevant wiring diagram and are only to be done by a certified
electrician. The fans may not be operated with transformer controllers.
All relevant safety regulation, national standards and norms are to be adhered to.
4.1 Electronic control board
The electronic control board allows the operation with 2 speeds (75/90 m
3
hr) for QT100T and (150/170 m
3
hr) for
QT120T. The control board is fitted into a splash-proof casing.
EMV regulation
Important indication for the electromagnetic compatibility
Interference resistance according to DIN EN 55014-2 depending upon impulse form and energy rate of 1000 V to
4000 V. With operation with fluorescent tubes, switch power supplies, electronically regulated halogen bulbs etc. these
values can be exceeded.
In this case additional suppression shielding activities are necessary (L -, C or RC elements, protection diodes,
resistors).
5.0 Cleaning and maintenance
- Before cleaning, ensure that the fan is isolated from the power supply.
- Prevent unintentional restart !
- Clean device only with a damp cloth.
- The device is maintenance-free.
5.1 Dismantling of fascia
Procedure:
1. Isolate the device from the power supply and prevent unintentional restart!
2. Remove the fascia (1) by using the correct tool (e.g. screw driver) and applying light pressure on the spring catches
left and right of the fascia (Fig.10).
3. Unfasten the screws of the control board cover (2) (Fig.11).
6.0 Troubleshooting
- If the thermal protection trips this could be the result of dirt build-up, a hard running impeller and/or bearings.
Too high winding temperature through insufficient motor cooling, or too high air flow temperature could be the cause
of disturbance.
- Abnormal noises can mean worn out bearings.
- Vibrations can originate from an unbalanced or dirty impeller or due to the installation.
- Extreme performance reduction can occur if the fan must work against too high resistance of the ventilation system
or if there is a lack of sufficient supply air (causing also higher sound level).

Electrical connection:
- Terminal N / L:
The supply voltage of 230 V is connected permanently to
terminal N/L
- Terminal 1:
The time functions are activated via terminal 1.
The following functions are implemented:
1. Start delay (0 sec, 45 sec, 90 sec, 120 sec)
DIP-switch S1-2
(see wiring diagram SS-920.2)
After switching on terminal 1, the fan starts first after the adjusted
delayed time. Thus a room can be entered for a short time (via
two-pole switch) e.g. during combined on/off switching with the
light without the fan being started for operation. Factory setting
approx. 120 sec.
2. Operation with push-button switch
During start delay the fan can be switched on via terminal 1 with a
push-button switch at deactivated start delay (sampling pulse min.
0,5 sec.).
3. Run on time (6 min., 10 min., 15 min., 21 min.)
DIP-switch S3+4
(see wiring diagram SS-920.2)
After switching off terminal 1, the fan keeps running and switches
off after the adjusted time automatically. Factory setting approx.
15 min.
4. Interval operation (0 hrs., 8 hrs., 12 hrs., 24 hrs.)
DIP-switch S5+6
(see wiring diagram SS-920.2)
The fan can be put in adjustable time intervals into operation auto-
matically. After the adjusted run on time the fan switches off auto-
matically. The interval time starts after the last switch off process
on terminal 1 (time input), also with manual operation in the mean-
time (terminal 2). The manual operation does not have influence on
the interval operation. The turn-on time in the interval operation
corresponds to the adjusted run on time. Factory setting approx. 0
hrs.
In delivered condition the interval operation is deactivated. The DIP
switches have to be adjusted according to the table for a desired
interval.
5. Changing the factory setting
DIP-switch (see wiring diagram SS-920.2). Isolate the unit from the
mains electric supply !
- Terminal 2:
The continuous operation is activated via terminal 2 (see wiring
diagram SS-917). With activated time function, the manual stage
(terminal 2) is inactive.
Room lighting
In connection with the room lighting (terminal 1 or 2), a two-pole
switch must be used.

Important: Wiring in parallel
Wiring in parallel of several fans is not permitted.
- Jumper
Depending on the jumper setting, the fan QT100T runs with 75 or 90 m³/h or rather the fan
QT120T with 150 or 170 m³/h.
Jumper 1 (see wiring diagram SS-931)
QT100T / QT 120T
Position A – Factory setting
Kl. 1 = 75 m³/h / 150 m³/h, activation via time function
Kl.2 = 90 m³/h / 170 m³/h, manual on
Position B
Kl.1 = 90 m³/h / 170 m³/h, activation via time function
Kl.2 = 75 m³/h / 150 m³/h, manual on
Operation test – Test mode:
When applying the supply voltage the fan is in the test mode for 1 minute.
(Requirement: Factory setting of DIP-switch, see wiring diagram SS-920.2)
In this case the delayed start and the overrun function is deactivated within the first
minute, or for a switching cycle.
