It's designed to regulate the fan's variable speed, and you can select either PWM or 0-10V output modes to control it. For each Tent-X, you'll need a corresponding EFC-1 for both Exhaust (F1) and Intake (F2) lines. That means one EFC-1 is required for each Exhaust (F1) or Intake (F2) line. KEY VALUES LCD Display for PWN 0-10V Mode Addressing Seamless Connection with Tent-X Main Controller and EC Fan Plug & Play
