the corresponding button. If the shutter was already in movement, these
orders are interpreted by the actuator as a stop order.
h) Lighting control
The lighting control function permits making use of the two buttons in the box to
send orders to a light dimmer, either though a binary object or through a 4-bit
object. Moreover, the box will permanently display the current value of the
dimming status object, which needs to be linked to the analogous object from
the dimmer (as it does not get automatically updated on button presses).

The available parameters are:
 Action: sets which of the two buttons will send the “turn on” orders and
which the “turn off” orders. Options are “Left Off, Right On” (default) and
“Left On, Right Off”.
 Dimming step: sets the increase or decrease in the light level (in terms of
percentage) the dimmer must perform with every step order. How step
dimming works is detailed below.
Setting up a box as a dimming control brings up the objects [Pn][Bi] Light
indicator (1 byte), [Pn][Bi] Light On/Off (1 bit) and [Pn][Bi] Light dimming (4
bits). The former acts as the dimming status object, which is required to be
linked to the analogous object from the dimmer and whose value, in
percentage, will be permanently reflected in the box. On their side, control
orders will be sent through one of the two remaining objects:
 After a short press on the “turn on” button, the value “1” will be sent
through the [Pn][Bi] Light On/Off binary object, while a short press on the
“turn off” button will trigger the sending of the value “0”.
