4.0 Functional description M1/150 N / C
1. Activation delay
The fan only activates after the set delay time (0, 45, 90, 120 sec.). Thus a room can be entered in case of activation
together with the light, without the fan going into operation. The activation delay is only implemented when the fan is at
a standstill. When switching between running stages, the applicable activation delay is ignored. In case of the simulta
neous activation of both stages, the activation delay will also be ignored.
2. Push-button operation
If an activation delay is not activated, both fan stages can be controlled with a push-button. For this purpose, the time
function must be activated on the respective stage.
The push-button must be pressed for longer than 0.5 sec. If a stage has been activated with the push-button, the
corresponding stage will automatically deactivate after the overrun time.
3. Overrun
After the deactivation of the respective stage, the fan will deactivate after the set overrun time. The length of the over-
run time is adjustable (6, 10, 15, 21 minutes).
When switching between the stages, the overrun time is ignored. With regard to the simultaneous deactivation of both
stages, the overrun time will only be considered if the time function is activated on both stages.
4. Interval operation
The fan can be automatically operated in adjustable intervals. The intervals can be adjusted (0, 8, 12, 24 hours). In
interval mode, the set overrun time corresponds to the running time. Interval operation starts after the last switch-off
process. The required ventilation is superordinate to interval operation. In case of intermediate required ventilation, the
started interval time will be reset and restarted after deactivation.
