Installation and Operation Instructions
UK
Electrical connections:
- Terminal N / L:
The supply voltage of 230 V is connected permanently to terminal N/L.
- Terminal 1:
Input with optional two functions!
Switching on terminal 1 offers two options depending on the setting of dip
switch S1-6, delayed start and overrun or deactivation of the humidity control
- see sections 2. and 3. below.
Terminal 2:
Switching on terminal 2 is to switch the second speed on/off manually (see
wiring diagram SS-919). This action does not affect the two options offered
by terminal 1 and/or the humidity control, i.e. during activated humidity con-
trol and/or time function (terminal 1), the terminal 2 is inactive.
1. Functional description of the automatic humidity control:
With normal increase of the humidity the fan starts automatically when the set
point is reached. With fast increase of the humidity the ventilation starts be-
fore the actual selected set point of 60-70-80-90 % relative humidity (factory
setting: 70 % relative humidity). The fan switches off automatically when the
humidity is reduced to 10 % below the set point. If the relative humidity in the
room decreases little within certain time, the fan changes into a defined inter-
val operation. The fan switches off automatically when the humidity is redu-
ced to 10 % below the set point. Possible reasons that the relative humidity
in the room decreases little within certain time may be high humidity ambient
air (summertime) or intense humidity supply in the room over several hours.
2. Operation mode N = Terminal 1, DIP-switch S1- 6 set to off (factory
setting)
Delayed start and adjustable overrun. Switched on with delayed start or
push-button switch (operation with push-button switch without start delay).
Delayed start (0 or 45 sec.)
When switching on the terminal 1, the fan starts after the set delayed start ti-
me. Thus a room can be entered and left within a short time without starting
the fan (e.g.via double-pole light switch) Delayed start factory setting approx.
45 sec.
DIP-switch S1.1 wiring diagram SS-941: No 1. : Off = deactivated, ON = 45
sec.
Operation with short power on
The fan can be run for the selected run on time using a short power on from
a switch or a push button switch providing a short pulse of current (minimum
pulse 0.5 seconds). The DIP-switch setting SI-1 must be set to off and a cho-
sen run on time -. DIP-switch setting SI-2 & 3 (see wiring diagram SS-941)
After switching off terminal 1, the fan keeps running and switches off after the
run on time automatically. Factory setting approx. 6 min. This operation has
priority over the humidity control.
or
3. Operation mode Deactivation of humidity control
= Terminal 1, DIP 6
set to on. Switched with push-button switch
With a short
power on from a switch or a push button switch providing a
short pulse of current (minimum pulse 0.5 seconds) the humidity control is
switched off for 1 hour. All memory states are deleted. When the switch is
operated within the 1 hour the 1 hour deactivation period restarts. The deac-
tivation has no influence on the manual operation (terminal 1).
4. Changing the factory setting
The DIP-switch settings shown on wiring diagram SS-941can be changed to
achieve the required operation. Isolate the unit from the mains electric supply!
5. Room lighting
In connection with the room lighting (terminal 1 or 2), a double-pole switch
must be used.
6. Wiring in parallel
IMPORTANT:
Wiring in parallel of several fans is not permitted.
7. Jumper settings wiring diagram SS-940
Depending on the jumper setting, the fan runs with 75 or 90 m³/h (Type
M1/100 F) or 150 or 170 m³/h (Type M1/120 F) .
Jumper 1
Position A – Factory setting
Kl. 1 = 75 or 150 m³/h, activated via time function or determined by humidity
Kl. 2 = 90 or 170 m³/h, manually activated without additional options
Position B
Kl.1 = 90 or 170 m³/h, activated via time function or determined by humidity
Kl.2 = 75 or 150 m³/h, manually activated without additional options
8. Test mode and calibration at initial start-up
When applying the supply voltage the fan is in the test mode for 1 minute (Re-
quirement: Factory setting of DIP-switch, see wiring diagram SS-941). In this
case the delayed start and the overrun function is deactivated within the first
minute, or for a switching cycle. The humidity sensor needs approx. 1 hour
to calibrate itself at initial start-up (switch on mains supply). Within the cali-
bration time the fan may switch itself on, dependent on the environmental
conditions.
