Good day thisandthat,
Douglas tends to be very, very protective of their info and devices and so very little hands on tech info exists outside of Douglas and their distributors/installers. In fact Douglas will not even quote you on any of their devices except for their relays and perhaps switches unless you provide full disclosure as to who the end customer is, etc.
Consequently, I do not think that you will find any publicly available info on setup, commissioning, etc of their devices. If you do find anything, please post up.
Cheers,
Sam
