The Amazon Supplier shipped the wrong product. I bought the correct product at Home Depot for a dollar more than the Amazon Supplier. This Supplierhas poor Quality Control in it's shipping department. Will Not buy from that supplier Again!

Perfect replacement for my attic fan thermostat. Installed myself and rewired it into the fan. It has been working all summer. No problems.

While the switch works, it is not at all accurate. I have my switch set to 80° and it's been known to kick on well above 85° and not shutoff until as low as 72°. I just suffer it to be so, just be aware.

Used this to wire up my exhaust fans in my shop. It works well. It's pretty hot here in Florida so the fans probably runs more than the average unit- depending on what region you're in I suppose. If you don't know what you're doing around electricity, I would suggest getting an electrician to wire it up for you.
