EFC-1
The EFC-1 is specially designed for use with the Tent-X control system to control the variable speed of the EC fan. The EFC-1 must select the output mode to control the EC fan in PWM or 0-10V.
Each Tent-X can connect a corresponding EFC-1 for extraction (F1) and intake (F2). Each extraction (F1) / intake (F2) line requires one EFC-1.
