Frequently asked questions
What does the EC2 Controller do?
The EC2 is an active controller that controls intake and outtake EC fans thermostatically. You set maximum and minimum speeds for the outtake fan and the intake follows.
How do I set negative pressure with the EC2 Controller?
The built-in fan balancer lets you fine-tune the difference in speed between the intake and outtake fans, so you can set the negative pressure you want.
Does the EC2 Controller need its own power supply?
No, it is powered from your fan so no power pack is required. It plugs directly into all of Systemair's EC fan range.
