A friend of mine worked on this porject and just wanted to share it with you all.
Here is the finished installation of my waterfall freeze protection project.
I found a GREAT box for the installation at Home Depot (top box in first pic). It is a sprinkler
timer cabinet made by Orbit (model #57095). It is lockable, weather resistant, and it has an internal GFI to provide power to everything. It was $30 - a bargain. The Ranco probe wire is coiled behind the mounting plate and exits the bottom of the Orbit box.
I have the Ranco unit setpoint at 37 degrees F, with a 3 degree differential - when the temperature reaches 34 degrees (37-3) it provides contact closure for an I/O module. The I/O module then sends a link to six waterfall relay switches, and doesn't turn them on again until the ambient warms to 37. I may need to play with setpoint and differential a bit, but I think this will be fine.
It works great, and the Orbit box was the perfect solution for the installation.
Tomorrow I'll be attempting the pool valve control.
