OPERATION MODES
Functionality by control of EXTA LIFE system transmitters.
• Lighting luminous flux intensity adjustment is possible only in case the dimmer's load is
switched off.
• Brightening the lighting level from the minimum to the maximum is realised according to the
adjusted 'brightening time'.
• Dimming the lighting level from the maximum to the minimum is realised according to the ad-
justed 'dimming time'.
• Brightening and dimming times can be configured in the range from 1 to 30 seconds by means
of a mobile application in coordination with the EXTA LIFE controller. Default time is 1 second.
• The RDP-21 dimmer is equipped with level memory – the adjusted luminous flux intensity is
remembered by the dimmer, after it has been switched off (in a typical configuration, it does not
refer to a switch off due to a power supply failure).
• Particular push-buttons of extalife radio transmitters can be assigned to operate in four modes
(see Programming push-buttons of EXTA LIFE radio transmitters):
2 PUSH-BUTTON MODE
Two push-buttons of a transmitter are always used in the 2 push-button mode to control a dimmer.
Short pressing of one push-button always realises the "switch on" function, and short pressing of the
second one always realises the "switch off" function. The lighting luminous flux intensity adjustment
is realised by a longer pressing of an appropriate transmitter's push-button:
• longer (>2s) pressing of the "switch on" push-button realises the brightening function up to the
maximum level
• longer (>2s) pressing of the "switch off" push-button realizes the dimming function up to the
minimum level.
CAUTION: The 2 push-button mode is recommended to control a larger number of dimmers
by means of one dimmer.
1 PUSH-BUTTON MODE
Only one push-button of a transmitter is used in the 1 push-button mode to control a dimmer. Short
pressing of the push-button always realises the "switch on" and "switch off" functions, based on
a cyclical change of the dimmer's output mode. The lighting luminous flux intensity adjustment is
realised by a longer (>2 s) pressing of the transmitter's push-button. After the dimmer is switched
on, pressing the push-button for a longer time realises the brightening function to the maximum. If,
after reaching a certain lighting level, the push-button is released, then another longer pressing the
push-button will realise the dimming function to the minimum level. If the transmitter's push-button
is pressed all the time, then the lighting luminous intensity adjustment is carried out continuously in
a brightening sequence to the maximum level - in a dimming sequence to the minimum level, etc.
CAUTION: 1 push-button mode enables an independent control of a larger number of re-
ceivers by means of one transmitter (e.g. by means P-457/4 remote control, it is possible to
control four RDP-21 dimmers maximum).
In the 1 push-button mode, it is not recommended to assign the same push-button to few dimmers.
During operation in such a configuration, a jitter may occur.
