Frequently Asked Questions - 845 26 LEGRAND

How to install the LEGRAND 845 26 switch?

Installation must be carried out by a qualified electrician. Cut off the power before any intervention. Connect the wires according to the diagram provided: phase to L, neutral to N, and the shutter control wires to the designated terminals. Minimum recessing depth: 40 mm.

How to program a scenario with this switch?

To create a scenario, press the Learn button on the leader, then press the associated control key (Up/Stop/Down). Next, on each actor, press Learn then the key to associate. Finish by pressing Learn on the leader. The indicators turn off to confirm.

How to delete an existing scenario?

To delete a scenario linked to a specific key, press Learn on the leader, then hold the corresponding control key for 10 seconds. To delete all scenarios of the product, press Learn, then hold Learn again for 10 seconds.

Does this switch work with roller shutters of any brand?

The LEGRAND 845 26 is designed for the In One by Legrand range. It can control shutters equipped with a power line carrier compatible motor (EN 50065). For other brands, check compatibility.

What to do if the switch does not respond?

First check the power supply (power outage, circuit breaker). Ensure connections are correct. If the problem persists, reset the device by holding the Learn button for 10 seconds (factory reset).

Can I control multiple shutters with a single switch?

Yes, in Leader mode, the switch can simultaneously control other associated receivers (actors) via learning. The Up/Stop/Down keys will then act on the entire group.

What is the range of infrared signals?

The infrared range is typically 10 meters in free space, but may vary depending on obstacles. The switch receives signals to control its scenarios or other products in the installation.

How to replace the LEGRAND 845 26 switch?

To replace it, cut off the power, disassemble the old device, note the connections, then install the new one. Use a recessing box with a minimum depth of 40 mm. If unsure, call a professional.

The indicator blinks rapidly, what does it mean?

A rapid blink indicates that the product is in learning or programming mode. A slow blink means the scenario is open. An off indicator confirms the end of learning. Refer to the legend in the manual.

Is this switch compatible with an old electrical installation?

It operates on a voltage of 100-240 V~, 50-60 Hz, so compatible with most installations. However, it requires a neutral wire. Check for a neutral wire in your panel. If in doubt, consult an electrician.

Description

Operation

The individual shutter controller:

• 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 in the scenario.

As Leader:

The individual shutter controller can control the following using its Up - Stop - Down keys:

• The opening that is connected to its terminals
• The openings that are connected to the terminals of the other products associated with it (the actors).

Note: It is only necessary to learn the Up key. The Stop and Down keys are learned automatically.

As Actor:

The individual shutter controller can participate in 16 different scenarios, locally executing the Up - Stop - Down commands from the other Leaders.

It has an interface for the infrared signals that is used to control its scenarios and/or other products in the installation.

(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.
