I have a number of older Leviton switches, DZS15-1BL (I think that’s the suffix). They’re the style with just tap on tap off on the bottom of the switch, no upper rocker. I installed them some time ago, and paired them all up. Now, I need to re-pair two of them, and I can’t figure out how to get them in pairing mode. The directions tell you how to do a factory reset, but unless I’m completely blind they don’t say how to pair them. I’d appreciate any help I can get.
