AUX switch as multi-way with White Series dimmer?

I just had my electrician install a bunch of white series dimmers. I expected the AUX switches to act like 3-way and 4-way pairs. But he’s having trouble knowing what to do with them. The AUX switches seem to need pairing with the “main” switches instead of being wired to them. Which I get, easier to deal with.

My issue is I can’t find any instructions on how to pair the AUX switch with the white series dimmer. The instructions i found were for the Red, Blue and Black series.

Any help would be greatly appreciated!

You don’t “pair” them, you connect them to the to the main switch. The Aux switches use a traveler/signal wire from the main switch from the Traveler terminal, and are also connected to a Neutral wire when the switch is also wired to a neutral or the Line wire for that circuit when the switch is wired without a neutral. Refer to the Wiring Instructions

You then need to make sure the Switch configuration is set to Multi-way Aux (Link to instructions for manual method) for the Aux switches to work correctly.
