Thermodynamic Wisdom...FWIW  :-)
Rusty, My logic is that a thermostat stabilizes the temps and helps warm up
in winter conditions.  I will use one until I prove to myself that it
somehow hinders cooling and that I don't need a thermostat.
I made some interesting temp readings that I will post in a few minutes.
