Review on RANCO ETC-111000 Digital Cold Temperature Control: Versatile New Solution by Richard Rob

This controller is very well built and designed for use in harsh environments including marine applications. It's easy to install and the versatile design means you can use the same part. for 110V AC, 220V AC, 24V DC, 12V DC and many other electrical installations. I used it to replace a failed 16 year old controller. The entire installation, including removing the old block and programming the new block for my application, took less than 15 minutes. I highly recommend this item.
