Canuckwoods,
You have the wrong regulator. That link is to a solid state voltage regulator but with that type of controller you need to use a solid state relay. This should be the right one (bonus, it's cheaper):

I agree with SW, I have a DSPR400 with an external heat sink on the SSR. I have no trouble running 5500w at 240v for hours and the heat sink is never too hot to touch. No fans mean less noise and one less moving part to fail.
I know it's come up on other threads but most of the components can be wired up with light gauge wire. I used 18 gauge to hook up the controller and meter. Just make sure the complete circuit from the wall->SSR->heating element is all heavy enough to handle your load plus a bit.
i'm sure you've read this elsewhere, you don't need a meter, but it is nice to have. I find myself looking at it when I first start things up and things are too quiet. It's a quick confirmation that yes, things are working.
Not sure how you're switched now, but I have found a switch on the output invaluable so you can power up the controller and do any setup while not sending any power out, then switch on the element.
Hope that helps.
