excessive dust, temperature in excess of 40 °C or long periods at standstill (not running), please contact your local
dealer for advice. This also applies for special technical and electrical applications. The complete fan corresponds to
protection IP 45 (jet water-protected) , protection class II and is suitable for use in zone 1 of bathrooms.
The fan may only be used for its intended purpose !
1.7 Performance
The unit must be installed correctly to achieve the optimum performance. This applies to the installation of the unit, the
ducting and the replacement air supply.
If installing in a room where the fan can affect a fuel burning device (e.g. a gas boiler) which has a balanced flue, it is the
installer’s responsibility to ensure that there is sufficient replacement air to prevent fumes being drawn down the flue
when the fan is operating at maximum extract rate.
The catalogue noise levels stated are A-rated sound power levels LWA (to DIN 45635 T.1). The A-rated sound pressu-
re level LPA depends on the acoustic condition in the room in which it is installed. These affect considerably the adju-
sting noise.

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 elec-
trician. The fan 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 m3hr). 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).

Wiring diagram overview
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 (without or 2 minutes.)
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. 2 minutes.
DIP-switch S1-1 wiring diagram SS-920: No.1: off = deactiva-
ted, on = 2 minutes.
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., 12 min., 15 min., 21 min.)
After switching off terminal 1, the fan keeps running and switches
off after the adjusted time automatically. Factory setting approx.
15 min.
DIP-switch S1-2+3 (see wiring diagram SS-920)
4. Interval operation - Auto Refresh
Interval operation (4hrs., 8 hrs., 12 hrs., 24 hrs.)
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. 4
hrs.
DIP-switch S1-4+5 (see wiring diagram SS-920)
The interval operation can be deactivated with DIP switch S1-6,
set to “on”.
5. Changing the factory setting
DIP-switch (see wiring diagram SS-920). 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.
SS-931
Important: Wiring in parallel
Wiring in parallel of several fans is not permitted.
- Jumper
Depending on the jumper setting, the fan runs with 75 or 90 m³/h.
Jumper 1 (see wiring diagram SS-931)
Position A – Factory setting
Kl. 1 = 75 m³/h, activation via time function
Kl.2 = 90 m³/h, manual on
Position B
Kl.1 = 90 m³/h, activation via time function
Kl.2 = 75 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)
In this case the delayed start and the overrun function is deactivated within the first
minute, or for a switching cycle.
