Values of CTRL/FlwSpeed

The value is given in (m)Volts

The following values can appear:

  • 0 ( no sensor connected)
  • 0,5V (sensor connected ; fan off ; no pressure difference)
  • >0,6V and less then 4,5V -a fan active and sensor working.

The sensor works as follows: 0,5V is zero pressure. Every additional volt=75 PA pressure drop. Total range of sensor is 300 PA. (4,5V)

The pressure drop will rise with: fan speed and with filter dirt and voltage of power-supply.

To give any idea about the values:

M-unit with clean filter:

  • speed-1=0,67V
  • speed-2=0,82V
  • speed-3=0,94V
  • speed-4=1,28V

L-unit with clean filter:

  • speed-1=0,74V
  • speed-2=0,90V
  • speed-3=1,04V
  • speed-4=1,37V
