I imagine that if we bought identically sized springs with a lower spring rate that would effectively lower the opening temperature. I'll bet mcmaster.com would sell the springs. We'd just have to find out how to measure the spring strength. I'd be willing to bet that we'd have far fewer temp related limps if the thing would open at 200 instead of 240-250.
