Detailed functional description

1 . Automatic humidity control system
Connection: Mains supply 230 V to terminal N/L, terminal 1 and 2 remain free (SS-948)
Depending on the speed at which the humidity increases, the fan will start automatically. If the increase of
humidity is very fast, the ventilation starts before the actual selected set point of 60, 70, 80, 90 % RH (factory
setting 70 % RH). Depending on the reset point, the fan will automatically deactivate. The reset point is 10 %
RH below the set activation point.
If the relative humidity in the room does not decrease or only decreases slightly within a set period, the fan
will go into defined interval operation (see Chapter 4 Runtime limiter). Once the reset point of 10 % RH below
the activation point is reached, the fan will deactivate. A reason for not reaching the deactivation point may
be that the supply air is too humid (in summer) or intensive humidity supply in the room over several hours.
Function test Automatic humidity control system:
If the humidity required for the initial commissioning is not available, then the activation behaviour of the M1/100
F or M1/120 F can be checked as follows:
If a damp cloth is held below the facade, the humidity sensor will detect a rapid humidity increase and it will
activate the fan after approx. 180 seconds.
Switching threshold RH in % (70/60, 90/80, 80/70, 60/50), DIP switch S4+5 (see SS-941)
2 . Automatic humidity control system and time function
Connection: Mains supply 230 V to terminal N/L, switched phase via switch or button to terminal 1,
terminal 2 remains free (SS-1219)
Automatic humidity control system like in 1. "Automatic humidity control system", but the fan can also be
activated for a set period via a switch or button with a delayed start.
DIP switch S6: off (see SS-941)
Delayed start (0 or 45 sec.)
After the activation of terminal 1, the ventilation will only begin after the set delay period. Thus a room can be
entered with joint activation/deactivation with the room lighting (via 2 pol. switch) for a short time, without the
fan running. Factory setting approx. 45 seconds.
DIP switch S1.1 SS-941: No.1: off = deactivated, on = 45 sec. (see SS-941)
Button operation
If the delayed start is deactivated, the fan can be activated on terminal 1 with a button (button impulse at
least 0.5 sec.).
Overrun time (6 min, 12 min, 18 min, 24 min), DIP switch S1.2+3 (see SS-941)
After the deactivation of terminal 1, the fan will continue to run and will automatically deactivate after a set
period. Factory setting approx. 6 minutes.
The operation with time function will override the humidity control system.
