2 channel thermal diff controller [RE-wrenches]

[Kelly Keilwitz]

Thermal Wrenches,
Does anyone know of a differential controller that will do 2 (or more)
channels? It would be nice to control not only the solar circulator, but
also multi-tank recirculation (and/or diversion) with the same controller,
based on differential temperatures. Or, is it just as easy to use multiple
controllers?
Thanks,
-Kelly
