Retrofitting an exhaust hood that uses variable voltage AC to control the exterior remote fan motor (attached line diagram - remote blower cable).
I am upgrading the fan motor to an ECM motor that has an RTC FS-1 controller (see attached manual). The controller permits remote control via a 0 to 10 volt dc input.
As the hood and control are already installed and would require significant work to remove, retrofit or replace. How would it be easiest to convert the current variable AC output used by the current motor to a 0 to 10 volt DC output? I plan to run a new, independent power supply to the upgraded fan so as an option the existing power wiring may be used for control when safely isolated from the power side.
