Title: Not reliable to shut off
Product review: I've gone through two of the WIN100's, to turn an exhaust fan on in my small greenhouse at 90 degrees, and both units will often not turn the fan off if the temperature gets over 100. That causes the fan to keep running into the night, bringing cold evening air in, which I definitely do not want! (Mostly orchids in the greenhouse). Since I can't always be around to be sure the WIN100 turned the fan off at 89 degrees, I have replace this with something reliable.In the winter I used this unit to turn a heater on when the temp gets below 58, and it seems to work properly at these lower temps, but it fails with temps over 100. (And I'm in Sacramento... 100 in the shade, outside, is not unusual). It's top set point is 90 degrees, and it fails at just 10 degrees above that?! I tried setting at 89 and 88, but same result; this is a thermostat that can't take the heat.
