Title. We keep ours at 75F, parents do 77F, and in laws 68F. It made me curious what everyone else keeps theirs at?

Mine growing up used a bit of mercury in a sealed vial mounted to that bimetallic strip.

    any idea what the mercury was for? something about getting the heat in and out of the strip faster maybe?

    The Mercury is in a glass tube with two wires and the tube is attached to the bimetallic strip in such a way that the motion of the Mercury due to gravity as the strip moves will close the circuit between the two wires. The Mercury is just being used a liquid conductor.
