Everybodymakes a good point and coming from a 20 year career in the HVAC trade dealing with mix matched electronics my point is this, there is entirely too much electronic bling available for us to throw at our birds,
shy of being an engineer in electronics the more stuff you throw at your bird the more the likelyhood you'll have solid state incompatability problems bear this in mind
I have had to teach myself sometimes the expensive way which controls will mesh and which ones won't and this is no different there are alot of factors to be considered
when throwing an assemblage of electronic parts together and absolutely no mfgr can possibly cover all of the possible scenarios of all the available combinations that may be encountered.
My advice is to thoroughly read an understand in intimate detail the voltages, amperages, compatibility issues and anything else you can learn and if you have a question call the 800# in the back of the book and ASK detailed questions explaining your exact setup.
being a licensed maser technician I cannot even begin to lay claim to thinking I know it all, however the best source for info is and always will be just that "the source, the people who made it and developed it and tested it" if you can verbally give them a ladder diagram with figures in and out
often times they will arm you with all the info you need to make a very educated decision on your particular setup.
The only dumb question is the one you ask yourself when you take the walk of shame
