+ 5°C to +45°C 110 V 230 V 150 W 300 W 150 W 300 W 150 W 300 W Lampe incandescente Lampe halogène Lampe halogène TBT à transformateur ferromagnétique ou électronique Protection by electronic device: - If there is an overload and it is above the max. operating temperature, the product automatically regulates the power by lowering the lighting. - If there is a short-circuit or a very high overload, the dimmer switches itself off. Once the fault has been eliminated, the product is once again operational. Connection

Factory configuration The first time it is switched on, pressing the ON or OFF keys controls all the lighting points in the “In One by Legrand” installation. Pressing Learn(1) cancels this general control function. (1) Programming or learn key.

Description LEARN indicator lamp Command keys Infrared cell Command keys Communication media PLC => Mains-borne signalling IR => Infrared ID number LEARN key Operation The dimmer switch: - Using its ON and OFF keys it can simultaneously control a set of products (actors) that have been associated with it during the learn phase(1). It is then the Leader of the scenario(2). - Can be controlled by other Leader products. It is then an Actor. As Leader: The dimmer switch can control: - The lighting points that are directly connected to the open phase terminal, using the ON, OFF, + and - keys. - The lighting points associated with it (the actors) using the ON and OFF keys. As Actor: The remote control dimmer can participate in 16 different scenarios, executing the commands from the other Leaders. Locally: The dimmer switch can control: - The lighting points that are directly connected to the open phase terminal, using the ON, OFF, + and - keys. When the remote control dimmer is used in local control, it is possible to record a default light level. Setting the light level of the ON button (excluding learning procedure) : - Set the level using the + and - buttons - Press the + and ON buttons at the same time, for 5 seconds - The load will extinguish and light up again at the ON level The ON level is now saved. To record a light level during the learn phase, step 2 of the “learn scenario” becomes: Press LEARN Press the ON command key which must be associated with the leader Press the + or - command key to set the required lighting level (1) Learn phase: Operation to associate products so that they can be controlled simultaneously from a central point. This association is carried out by applying the learn scenario procedure on page 11. (2) Scenario: Corresponds to the set of products (actors) that are associated with a command key.

Learn scenario Step 1: Start the learn phase (on the LEADER) Press LEARN Press the command key that is to control the scenario Step 2: Add an actor to the scenario (on the ACTOR) Press the command key that is to be associated with the leader Press LEARN Step 3: Record the scenario (on the LEADER) The indicator lamps of all the products go off. The scenario is recorded. Press LEARN Modification of a scenario Step 1: Open the scenario (on the LEADER)

Press LEARN The indicator lamps of all the products in the scenario blink. Press the command key that controls the scenario Step 2 : Modify the state of an actor in the scenario (on the ACTOR)

Press LEARN Press the command key that is to be associated

To remove the product from the scenario, go to step 3 Step 3 : Record the scenario (on the LEADER) The indicator lamps of all the products go off. The scenario is recorded.

Press LEARN Clearing a scenario Clear all the scenarios linked with the command key (on the LEADER) The scenario is cleared Press LEARN Press the command key and hold it down for 10 s

Clear all the scenarios linked to this product (on the LEADER) Return the product to factory configuration Press LEARN Press LEARN and hold down for 10 s

Key The indicator lamp goes off The indicator lamp blinks slowly The indicator lamp blinks quickly
