Anyone here ever work with these PID gizmos?

They don't cost too much..
eBay -

And, they sound very interesting..
PID controller - Wikipedia, the free encyclopedia

I've seen were people are using these for fancy coffee makers, to keep their temperature at +/- 1deg..
I think they were using a digital pulse output to an SSR..

I've been looking at PIDs, wondering if they could be used to control the water temp,
in my boiler, by switching a ASHP off and on, (No digital pulses).

My first impression is, these PIDs are smart and learn when to shut down
early, before over-shoot comes into play.. Anyone up on these things?

Thanks,
Rich
