Good to know!! And back ups only prevent over heating right? Say the main stat failes and doesn't put out any power. Will the back up kick in then?
I wouldn't think so. But I'm not positive that's why I ask.
No. If your helix fails and puts out full power, the ranco will regulate it, and keep it to a max of 96. If your helix fails and puts out NO power, the ranco will put out full power, but none of that power will reach the heat source.
