Hello,
has anyone here experience with the decentralized venting system Vent 2000 D from Bosch/Junkers?
Especially about the control interface?
I read that the control panel (CV 40 H) is connected with 12V/GND/PWM lines to the venting units.
Does anyone know the frequency of the PWM or how the direction of the ventilation is controlled? E.g. <50% duty cycle one direction and >50% duty cycle the other direction?
Thanks for any hints!
