off and will be completely switched off after 30 seconds. Operating
the push button while the lamp is on will restart the timer.
2 or *A
Dimmer
A short press will turn on the lamp to full intensity. A short press
while the lamp is on will switch off the lamp. A long press will dim the
lamp until the maximum or the minimum is reached. A next
operation will reverse the dimming direction. After the set time (see
‘TIME’ rotary switch) has elapsed, the lamp will turn off.
3 or *B
Dimmer with memory function
A short press will turn on the lamp at the intensity which was last
used. A short press while the lamp is on will switch off the lamp. A

reached. A next operation will reverse the dimming direction. After
the set time (see ‘TIME’ rotary switch) has elapsed, the lamp will
turn off.
4 or *C
Multi-position dimmer
Operating the push button will turn on the lamp to full intensity. Each
time the push button is pressed within 5 seconds after the previous
operation the light intensity will modify with 25%. If the lamp is on
and the previous operation happened more than 5 seconds ago, the
lamp will turn off. After the set time (see ‘TIME’ rotary switch) has
elapsed, the lamp will turn off.
5 or *D
Slow-on dimmer
Operating the push button will turn on the lamp gradually. The time
needed for the lamp to burn at full intensity depends on the rotating
switch used to determine the time setting (see ‘TIME’ rotary switch).
Operating the push button while the lamp is on will switch off the
lamp immediately.
6 or *E
Slow-off dimmer
Operating the push button will turn on the immediately to full
intensity. Operating the push button while the lamp is burning at full
intensity will turn off the lamp gradually. The time needed for the
lamp to turn off completely depends on the rotating switch used to
determine the time setting (see ‘TIME’ rotary switch). Operating the
push button while the lamp turns off gradually will immediately turn
on the lamp to full intensity.
7 or *F
Slow on/off dimmer
Operating the push button will turn on the lamp gradually. Operating
the push button while the lamp is on will turn off the lamp gradually.
The time needed for the lamp to turn on or off depends on the
rotating switch used to determine the time setting (see ‘TIME’ rotary
switch).

Remarks:
The set mode is only applicable on push buttons connected to the direct push button input and to
push buttons connected via the Velbus® which were attributed the mode function in the learning mode (see
learning mode). If the TIME rotary switch is set on 0, the dimmer module will always operate in moment
control, regardless of the set operating mode. In other words: the light bulb will burn as long as the push button
is being pressed. If the TIME rotary switch is set on F, the dimmer module will not automatically deactivate or
the dimming speed will be at its peak if the module is set in slow on, slow off or slow on/off mode.
