Narrowed the new 'stat search down to 2 models: Robertshaw 7700 or 9610. However, I cannot seem to find any good information on the 7700, not even on their website.

Does anyone have specs on the 7700 other than what I can read on the package? It seems to be a newer model than the 9610 (judging by the shape of the thermostat case, etc), but Im not sure if it will work in my situation whereas I *know* the 9610 will.
