Title: Themostat is useless
Review: Everything about this fan is fine except the thermostat. It limit-cycles. That means, when the temperature is near the set point, it switches on and off continuously every couple seconds. This is way less efficient electrically, and annoying to listen to. Instead, a control loop needs to implement hysteresis, preventing this from happening. (This is elementary -- did they take an 8th grade science project for the design?)The cheaper model doesn't have the thermostat but everything else is the same. Buy that one. You're going to use this one in that mode anyway.
