2.2.2.1.3.8 Dimmer
The light control function permits making use of the two buttons in the box to send orders
to a light dimmer, either through a binary object or through a 4-bit object. Moreover, the
box will permanently display the current value of the dimming status object (“[Ci] Light –
Dimming Indicator”), which needs to be linked to the analogous object from the dimmer
(as it does not get automatically updated on button presses).
Figure 84. 2-Buttons Control - Dimmer
The parameters available are:
Maximum Dimming Step on Long Press [100% / 50% / 25% / 12.5% / 6.25%
/ 3.1% / 1.5%]: sets the increase or decrease in the light level that will be
requested, via object “[Ci] Light – Dimming”, from the dimmer with each long
press on the top or bottom button respectively.
After a short press on the top button the value “1” will be sent through the “[Ci]
Light - On/Off” binary object, while a short press on the bottom button will trigger
the sending of the value “0”.
Show Percentage Indicator [disabled/enabled]: enables or disables the shutter
status indicator in the box.
Note: most light dimmers implement light step dimming progressively (i.e., sending a
dimmer a step order of 25% typically does not imply that the light level is suddenly
incremented/decremented by 25%, but a progressive increment or decrement of the light
level by 25% which is in fact interrupted if a stop order arrives (such order is sent by Z70
v2 when the user releases the button). Due to this behaviour, it is advised to parameterise
dimming steps of 100%, so that the user can perform a complete dimming (from totally off
to totally on, or vice versa) or a partial dimming by simply holding the button and then
