I found a "how-to" article here on the forums on doing the installation. Basically, you're bypassing the slider temp controller and letting the PID do the work. You need a PID, an SSR, a heat sink, a K-type TC and a few miscellaneous parts. Auber sells most of everything you need.
Sounds like a lot of work but it wasn't all that difficult and compared to spending nearly $200 for a dual proble plug-n-play the cost is quite appealing.
