  • Hello! I've reviewed the technical user guide for SKOV DCT 920-1E and DCT 920-4E fans. This document details how to configure fan speed using the digital input D1, with options for analog signal control or fan stop. I'm ready to answer any questions you have regarding these fan models.
  • How is the fan speed controlled?
    What happens when D1 is connected to GND?

DCT 920 fan configuration of D1 control input.
In a DCT 920-1E and DCT 920-4E fan, the speed control is
activated via a potential-free contact at the digital input D1.
• D1 connected to GND:
The 0 - 10V (E1) analog signal controls the fan speed.
• D1 connected to 24V:
The fan is stopped regardless of the 0 - 10V (E1) analog
signal input.
