Product review (5 stars): Great equipment and at Great price
This does just what I wanted for an attic fan ventilation system. I is very accurate and remembers the settings
during power failers. Easy  to progam if you read the instructions. So much fun to play with I got one to control
the temp in my outside cat house. I put a 70 ft extension on the probe and didn't have to make any adjustments
to the temp reading.
