The benefit of the Paragon controller is that it is plug-and-play. It is self-contained. You plug the power from the furnace into the controller, insert the controller thermocouple ( may need a new hole), turn the existing furnace controller all the way up, and then run off the new digi controller. The thing I like about the Paragon digicontrol is that it can be a full keypad instead of those agrravating two-key scroll controllers. I'll always like direct entry.
That said, I think in this case Robert, given the cost due to the large-amperage furnaces you have, I agree that it would be of most benefit to spring the little difference and just get a new Evenheat. Even if it doesn't have the multi-key controller. They're nice units; I like mine. (I'd like my Paragon better than the Evenheat if it was digital, though!)
OT, so, these guys got a Nobel for playing with their Bucky-balls??
Sorry, somebody had to say it.....
