I am trying to install a three-way dimmer for the lights. I mistakenly installed the residential switch for the master (WS12A) and the pro version for the slave (XPSS). Obviously it is not working correctly. My question is: which version is better - Pro or residential? Should I replace the master with the XPD3 or replace the slave with WS14A. The WS12A feels a bit flimsy; is the pro version more solid?
Thanks
