Hayden, Inc. 3647 Cooling Fan Control

Worked great, description matches what the unit does. Easy to install and replaced a faulty FlexLite unit. The only thing missing is the ability to have a manual switch to turn the unit on. I got around this by installing a second relay that bypasses this automatic unit.

This item is 100% better than the old one. The price I paid was not the cheapest nore the most expensive. The control is just what I needed.
