I swear I've searched, but I can't find any reference to the correct t-stat for an east coast U.S M110, 73 280.
79 or 87?
It has a 79 and seems to be running on the cool side. And winter is coming too. Thoughts?

They come in 3 versions
71/79/87.

You want a 87 for winter climates, and you should be able to run that year round, but I am Old School and would change back to the 79 in Summer . specially if your car has A/C.................

Gotcha, the 87 was my guess, and what I ordered. The thing just feels too cool running this time of year to me.
