6.1.
Minimum Ventilation
6.1.1. Principle of Operation
Definition:
Minimum ventilation cycles are
activated when the room temperature is
lower than the start temperature of the first
fan/tunnel fan group. Running the fans even
though ventilation is not required for reduc-
ing the room temperature is useful to reduce
humidity levels and supply oxygen to the
room. It also prevents the fans from freezing
in winter.
Minimum Ventilation Timer:
The minimum
ventilation timer is composed of an
“On Time”
and of a
“Cycle Time”
. The fans run during
the
“On Time”
and then stop until the end of
the
“Cycle Time”
. This timer is common to all
programs of the controller.

The controller can extract the warm air
from the attic by increasing the operating
time of the fans in minimum ventilation.
