Steve,

I doubt you'll be able to answer that question until the units are 
installed.  RFI is such a tricky thing to predict, and equally tricky to get 
rid of.  I suppose you could take the brute force approach of putting 
torroids on any and all control lines going into and out of the house, but 
even then you could still have trouble if a stray signal gets into some 
piece of electronics in the system.
