CONNECTION
ll work must be carried out with the equipment fully isolated from the power supply. The electrical connection
W RNING
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
PCB with automatic humidity control and timer. The control board is fitted into a splash-proof casing.

NOTE
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).

Cleaning and maintenance
CLE NING ND
- Before cleaning, ensure that the fan is isolated from the power supply.
M INTEN NCE
- 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).

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
TROUBLESHOOTING
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).

Terminal N/L:
A permanent supply voltage of 230v/1Ph/50-60 Hz should be
connected to terminals N and L, for ALL installations. The unit is double
insulated and does not require an earth. (drawing SS-919)
You need an additional switched live to Terminal 1 OR/AND Terminal 2
to give your fan its functionality.
Terminal 1 Functionality
Factory set 2 minute delay start,15 minute timer overrun and humidity
sensor is also live and active. (drawing SS-919)
Terminal 2 Functionality
Fan performs at a second speed by way of a second switch . (drawing
SS-919)
TERMIN L 1 ND TERMIN L 2 FUNCTION LITY
The fan functions as outlined in Terminal 1 above, when Terminal 1 timer
delay or run on timer or humidity is not activated, then a separate switch
wired to Terminal 2 enables you to use the second speed. . (drawing
SS-919)
See also notes 1, 2 and 3 below for more detail
1. Standard functionality out of the box with Terminal 1 ONLY used
This option activates a 2 minute delayed start and timer overrun and
makes the humidity function live.
Delayed start 2 minutes
This energy saving function enables a short visit without the fan turning
on. A useful facility, particularly at night.
Run on Timer
When the fan has been activated by a switch, the 15 minute run on timer
is also activated when the switch has been turned off.
utomatic Humidity Control
With a progressive increase in humidity the fan will start when the pre-
set value (factory setting 70% RH) is reached. However, when the
sensor detects a rapid increase in humidity the fan will start
automatically before the pre-set value has been reached so that
preventive ventilation commences.
The fan switches off automatically when the humidity is reduced to 10%
below the set point.
Note: It is possible that a high level of humidity is present within the room
for a longer period of time due to generally high humidity in the ambient
air (summertime) or a build up of high humidity over several hours
(stream rooms/sauna etc)
2. Standard functionality out of the box with Terminal 2 ONLY live
Fan operates by a remote switch at the speed set in terminal 2.
3. Standard functionality out of the box with Terminal 1 ND 2 live
This option gives you all the functionality of terminal 1 as outlined above
and the functionality of terminal 2 as outlined above. However terminal 2
only functions when none of the functions of terminal 1 are active.
Test mode and calibration at initial start-up
When applying the supply voltage the fan is in the test mode for 1
minute (Note: Factory DIP switch settings must be in accordance with
wiring diagram SS-941.2). In this mode the delayed start and the overrun
timer functions are deactivated within the first minute.

The humidity sensor needs approximately 1 hour to calibrate itself at initial start-up (from switch
on of mains supply). During the calibration period the fan may switch itself on, depending on
the prevailing environmental conditions.
DDITION L FUNCTION LITY
De-activating the Humidity sensor temporarily
When a short switch on and off (minimum pulse 0.5 seconds) is supplied the humidity control
is switched off for 1 hour.
In this mode all other settings are by-passed. When the switch is operated again within 1 hour
the deactivation period is reset back to 1 hour.
Deactivation of humidity has no effect on the manual operation settings of terminal 2
CH NGING TERMIN L SPEEDS
The standard speed for terminal 1 is 75m³ and terminal 2 90m³. These can be changed
around so that Terminal 1 is 90m³ and Terminal 2 is 75m³
Please see drawing SS-931 and jumper configuration.

Changing the factory setting
The DIP switch settings shown on wiring diagram SS-941.2 can be changed to select alternative
functionality . The additional functionality are: disable 2 minute time delay, adjust the run on
time, adjust the humidity levels at which the fan is activated disable the run on timer and disable
the humidity function.
Always isolate the unit from the mains electric supply before commencing any work.
Room lighting
When connecting the fan to the light switch (terminal 1 or 2), a double-pole switch must be
used.
Wiring in parallel
IMPORTANT: Wiring in series of more than one fan is not permitted.
