On this topic I have
a real winner "Shade Guy" send this to me, once... And when a say
winner, I mean
full-blown retard! I asked a GC to get me a spec +/or cut-sheet for some shades at a job, as "Motorized shade" is just not enough on a set of plans... He calls the guy, and 3 days later he sends this...
He sent a pdf file named
Stay out of trouble for electricians . The GC reads it over, and contiplated for 2 more days while trying to get this dope to understand what "Specification" meant... (never-mind "cut-sheet") Frustrated with me hounding him as this place was about to rock - gives it to me.... And we both died laughing - its a page out a training manual that Jeff Spiccoli could have written. (And goes to show what that company thinks of Electricians.)
Bottom line is you need to know what manufacturer you are going to be dealing with in very least. (BTW the company listed on that sheet was not what was installed....
Nor was it wired that way.) And you will need to know the model# and how many motors will be used. They are all pretty different... Sivoia QED is set up with a remote transformer that is operated by key-pads, or other automation. Others will have just a 3-wire from a 3-way switch, some will have double motors large enough for a circuit each... and have a DPDT, and others will need momentary switches. And the list can can go on as they are not standardized.
And a great way for a "Shade Guy" not to get smacked around a job-site is to provide you with a spec or cut-sheet...
