CHAPTER 7
FUNCTION
M1/100/120 N / C
WARNING
- 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-920.1)
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. 45 sec.
2. Operation with push-button switch
During start delay the fan can be switched on via terminal 1 with a push-but-
ton 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-920.1)
After switching off terminal 1, the fan keeps running and switches off after the
adjusted time automatically. Factory setting approx. 6 min.
4. Interval operation (0 hrs., 8 hrs., 12 hrs., 24 hrs.)
DIP-switch S5+6 (see wiring diagram SS-920.1)
The fan can be put in adjustable time intervals into operation automatically.
After the adjusted run on time the fan switches off automatically. The interval
time starts after the last switch off process on terminal 1 (time input), also with
manual operation in the meantime (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.
The interval operation can be deactivated with DIP switch S5-6, set to "off".

Electrical connection:
5. Changing the factory setting
DIP-switch (see wiring diagram SS-920.1). Isolate the unit from the mains el-
ectric 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 M1/100 N / C runs with 75 or 90 m³/h
or rather the fan M1/120 N / C with 150 or 170 m³/h.
Jumper 1 (see wiring diagram SS-931)
– M1/100 N / C
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
– M1/120 N / C
Position A – Factory setting
Kl. 1 = 150 m³/h, activation via time function
Kl.2 = 170 m³/h, manual on
Position B
Kl.1 = 170 m³/h, activation via time function
Kl.2 = 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-920.1)
In this case the delayed start and the overrun function is deactivated within
the first minute, or for a switching cycle.
