On DD f/w side, this should just be a simple pump controller. States should be Off and On (control to commanded Qsub). There is no flow sensor for feedback control, so assuming this is open loop similar to UF pump.
GenDialysate mode will have an HDF sub-state that signals this controller from Off to On and would also call separate controller for heater and separate (Switches) monitor for door sensors.
