Okay so critical has different levels! I mean more along the lines of a boiler plant or chiller plant. Still not what the industrial world would call critical.
I guess what I was looking at is based on cost, which obviously varies based on who's buying and selling, a Spyder and a JACE can be competitively priced. As a building owner, why would I want the Spyder instead of the JACE? I'm not using this JACE as the front end, just simply an equipment controller.
