Thanks to all that replied on and off list . A Friend that lives close called telling me, he has a new RC-2800-P controller that  I could use to do my testing ..

##  Which version of the M2  controller, do you have ?   The latest version
is called a RC2800PXAZ..and uses a switching supply...good  from
88-264 vac.

##  Does your controller have a MOV  on the 120 vac  input ?   Mine doesnt,
thats most of your problem  right there.  The  130 vac rated mov can  installed 
inside
the  controller, between hot  120 leg...and  chassis.  For the price of the 
controller box,
you would have thought they woulda  spent the extra  1  dollar, to install a HD 
MOV
across the  incoming 120  vac.

##  Ideally,  you want MOVS right at the main  200A  entrance panel.  Typ they  
will use
a  2 pole breaker installed into a spare slot in main panel.... then cabled 
over to  commercial
MOV box.   MOV box will  consist of  2 x   130 Vac  MOVS, one from each hot 
leg..to neutral.

##  Then, everything in the home is protected.   Otherwise, you could easily 
get a repeat performance.
make sure the  GH box  has a MOV across the  incoming 120 vac line too.
