Functional description M1/100/120 N / C

With integrated, interval control, which enables automatic fan operation in preset intervals. The fan can be activated
with an external switch (possibly connected to light) with approx. 45 sec. activation delay and approx. 6 minute over-
run (time input)). This resets the interval time, which starts again after the overrun time. Manual control (on/off) in par-
allel is also possible via a switch, but the function input has priority over this.
Setting options / factory settings*:
- Activation delay: 0, 45 sec*., 90 sec., 120 sec.
- Overrun: 6*, 10, 15, 21 min.
- Instead of the activation delay, a push-button switch can also be connected (switch impulse min. 0.5 sec.), which
activates the fan for the set overrun time when switched
- Interval operation: 0 hrs, 8 hrs, 12 hrs, 24 hrs; lower stage, higher stage
- Manual control (switch): Lower stage, higher stage
The settings may only be changed by an authorised electrician!
The following functions are implemented:
Activation delay
After activation, the fan will start after the set activation delay. Thus, a room can be entered in case of activation/de
activation together with the light (via 2-pole switch), without the fan going into operation.
Overrun
After deactivation, the fan will continue to run and deactivate after a set time.
Interval operation
The fan can be put in adjustable time intervals into operation automatically. After the adjusted run on time the fan swit-
ches off automatically.
The interval time starts after the last switch off process on terminal 1 (time input), also with
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.
In delivered condition the interval operation is deactivated.
Test mode
When there is no voltage present (power failure, fuse, etc.), the fan is in the test mode for 1 minute (Requirement: unit
with factory setting. In this case the activation delay and the overrun function is deactivated within the first minute, or
for a switching cycle.
