Not heated or made warm.

Unwarmed → It is formed from "un-" (meaning not) and "warm" (from Old English "wearm", meaning having a moderate degree of heat). The word "unwarmed" means not having been heated or made warm.
Think of 'not' ('un-') having 'heat' ('warm') — that's why unwarmed means something that hasn't been heated.
