Hi parroty40:
Sorry, I guess we miss some posts. I can't speak for
Sadoun as I'm not affiliated with him, at least not with his business concerns. We all try to answer all posts but some fall through the cracks. Yours was one of them.

ops:
Anyway, I have the
HH100 motor and it works fine in all weather extremes even in Toronto winters, which I suspect are a bit milder than Indiana winters; however my answer to your question is --
HH motors are not affected by cold temperatures. I'm talking about the
STAB kind made in Italy -- not sure about the other brands.
What are your other concerns? I see only two posts under your nick.
