01 Introduction
Congratulations on your DucoBox Silent,
the quietest box in Europe! The
DucoBox Silent performs two functions
in a Duco Demand-Controlled Natural
Ventilation System:
On the one hand it is the extractor fan
that exhausts stale air with excessive CO
content or humidity�
On the other it is the system 'master'
or brain which receives and interprets
signals from slave components (meas-
urements from sensors or manual input),
on the basis of which it controls the
ventilation system�
It is inadvisable to connect the DucoBox
(via a duct or directly) to an extractor
hood, regardless of type� This usually
causes excessive fouling in the DucoBox,
which affects its operation or has a more
direct effect on output�
