Anyone know of a design for one of these with a display for turning on/off pumps and other filter stuff ?

I guess more of a programmable timer to operate some relays for turning on and off 220v pumps, 110v ozone and others for a hot tub.

TIA
 
What's your level of experiance?

A microcontroller would be the best option?

You could consider a PLC if you don't want to do any soldering.
 
I did some research on in-line heaters a few years ago and ran across a number of commercial controller packages. My guess is that they were micro-controller based. Sorry I can't help - except to suggest that someone probably does make them. Not sure if that's what you wanted. If you found the stuff you might look at info to see what features they provide - as a way of helping you define what you want.
