MCHXXX potentiometer models having either two or single 200 Ohm pots are configured to directly
control Danfoss variable pumps with electrical displacement controls (EDCs). Whether two or single pots,
both require the same electrical connection to the EDC and only one of the dual coils needs to be
connected to achieve forward and reverse pump flow.
