Preparing VELUX® wall remote control

This chapter explains how to prepare a VELUX® wall remote control before connecting it to E-VLXESP32.

E-VLXESP32 is compatible only with the following VELUX® wall remote models:

  • KLI311
  • KLI312
  • KLI313

Important

Connecting an incompatible VELUX® remote control may permanently damage both the remote and the E-VLXESP32.

Before you start

Ensure that your VELUX® wall remote control is correctly paired with your VELUX® motorized skylight window.

Note

Follow the official VELUX® remote control manual to pair a new remote with the skylight window.

Before proceeding, verify that you can open, close, and stop the skylight window using the wall remote buttons.

Required tool

You will need a small flat-head screwdriver.

Step 2 – Remove the batteries

Remove any batteries from the remote control.

Leaving batteries installed may damage the E-VLXESP32.

Note

Batteries are no longer required.
The E-VLXESP32 powers the VELUX® remote via pogo pins.

Step 3 – Remove the battery holder

Carefully remove the battery holder from the back of the front cover. Use the screwdriver to gently release the snap-fit mechanism.

Caution

Do not damage the snap-fit mechanism.

Danger

If the snap-fit mechanism is damaged, do not connect the VELUX® remote to E-VLXESP32. Misaligned pogo pins may cause electrical damage or malfunction.

Step 4 – Verify PCB compatibility

Ensure that the PCB on the back of your VELUX® remote matches the image below. All gold-plated pads must be in the same position.

Danger

If the PCB layout does not match, do not connect the remote to E-VLXESP32.

Step 5 – Verify Mechanical compatibility

The plastic enclosure of E-VLXESP32 is only mechanically compatible with the new VELUX® remote cover KLI311, KLI312, KLI313. As shown in the image below, make sure that the snap-fit mechanism indicated by the purple arrows matches the one on your VELUX® remote.

Note

Some older KL313 units may have been manufactured with a different internal mechanical design than the one shown above. E-VLXESP32 is not mechanical compatible with older KL313 VELUX remote.

Important

Do not attempt to install E-VLXESP32 in an incompatible remote. This may cause irreversible damage to both the E-VLXESP32 and the incompatible VELUX® remote.

Completion

Congratulations!
Your VELUX® wall remote control is now ready to be connected to E-VLXESP32.
