Got a simpler solution? I want the 3 temps so I can make the most energy
efficient decisions when I'm in heat mode (so pull warmer air into the
attic whenever it's warmer outside), or cool mode (pull cooler air into
the attic whenever it's cooler outside). Seems a shame to not take
advantage of the large daily temp differences enjoyed in this area.
