Prioritized Production, or processing of any kind can possibly benefit by using a controller to automate which "jobs" are placed into sequence. In this application, the processing is limited, filling in low priority "jobs" even as higher priority "on demand job processing" is most profitable. The circuit for the Inductive Load Center can be applied to control automated gates to a conveyor system...

Prioritized Zonal Heating seems a perfect second application for the circuit that prevents concurrent switching of inductive loads..

Prioritization can restrict power to manage slab heat, circulating glycol where needed. Winter heating of the insulated garage can be minimal, low priority. A basement, and two other areas can be prioritized. Using one circulating pump, valves can be controlled to save energy.

The Zonal Heating application application would use the same circuit, easily configured for different delays.

An interesting possibility could be explored in programming, considering the temperature differential between the desired value, and actual. Controller response might vary with deviation from settings to put actual temperature back within tolerances. This would only be possible if adequate heat source is available. Software can expand on prioritization, to provide improvement. If this the Zonal Heating application can be improved with programming, it may be easier to find additional applications, approaching them similarly.
