of the first
lateral fan
Startup of the
tunnel fan labeled
“Start Tunnel”
(see sec. 6.5.3).
Startup of the
tunnel fan labeled
“Close sidewall”
(see sec. 6.5.3).
In minimum ventilation, the fans that are
used to ensure a minimum ventilation run in
timer mode and the vents (sidewall and/or
attic) slightly open prior to each activation
of the fans.
In lateral mode, ventilation is provided by
chosen sidewall fans and the air intake is
provided by the sidewall and/or attic vents.
In tunnel mode, ventilation is provided by
chosen tunnel fans and the air intake is
exclusively provided by the tunnel inlet (the
sidewall vents are closed). The controller
starts measuring the average temperature
according to the tunnel sensors and starts
using the tunnel inlet static pressure limits
and alarm limits.
As the room temperature rises, the control-
ler can start opening the tunnel inlet before
closing the sidewall vents in order to create
a smooth transition between lateral & tunnel
ventilation. This transition is optional.

In minimum ventilation, the fans that are

of the fans. This ventilation mode is optional
in a turkey facilty.
In lateral mode, ventilation is provided by
chosen sidewall fans and the air intake is
provided by the sidewall and/or attic vents.
This ventilation mode is optional in a turkey
facilty.
In tunnel mode, ventilation is provided by
chosen tunnel fans and the air intake is
exclusively provided by the tunnel inlet (the
sidewall vents & natural curtains are closed).
The controller starts measuring the average
temperature according to the tunnel sensors
and starts using the tunnel inlet static pres-
sure limits and alarm limits. This ventilation
mode is optional in a turkey facilty.
In natural ventilation, no fan is running and
the air intake is provided by the natural ven-
tilation curtain and by the tunnel inlet (if a
tunnel inlet is used).
