Tunnel Ventilation 6.5.
6.5.1. Principle of Operation
The tunnel ventilation mode begins at the
startup of a chosen tunnel fan output. If the
lateral ventilation mode preceeds the tunnel
ventilation mode, the controller can make a
smooth transition between both modes by
opening the tunnel inlet prior to closing the
sidewall vents. Refer to the following sec-
tion of this manual to specify the moment at
which the transition begins and the moment
at which tunnel ventilation is fully enabled.
Temperature Sensors in Tunnel Ventilation:
When it is in tunnel ventilation, the controller
measures the room temperature according
to the temperature sensors that are associ-
ated with the tunnel fan output in use. The
sensors that are being used in tunnel ventila-
tion are specially defined to compensate for
changes in airflow patterns that can distort
the room temperature. Refer to section 4.5
to select the temperature sensors used in
tunnel ventilation.
Air Intake in Tunnel Ventilation: In tunnel ven-
tilation, the air intake is exclusively provided
by the tunnel inlets (the sidewall vent, attic
vents and natural curtains are closed). Up to
2 tunnel inlets can operate as a function of
the static pressure level or as a function of
the room temperature. Refer to section 4.4
of this manual to enable the tunnel inlets and
to choose their operating mode.
Low Static Pressure Alarm Limit: If the low
pressure alarm condition is used, the pressure
limit at which the alarm occurs changes when
the controller enters in tunnel ventilation. Re-
fer to section 13.2.2 to set the low pressure
limit used in tunnel ventilation.
Refer to the previous section to see how
the transition is made between natural
to tunnel ventilation.
6.5.2. Tunnel Ventilation in
Standby
The controller allows putting tunnel ventila-
tion on standby at any moment. This is useful
to prevent the tunnel inlet from opening when
the animals are too young or when it is too
cold outside for instance. If the tunnel mode
is on standby and the room temperature is
suitable for tunnel ventilation, the controller
will not switch to tunnel ventilation and will
keep using the highest level of ventilation.

* * Tunnel settings
* This menu is accessible if at least 1 inlet is enabled
in the Set-up menu (see section 4.4). A password may
also be required to access it (see section 4.2.1).
* * This menu is accessible if the tunnel inlet is en-
abled in the Set-up menu (see section 4.4).

To modify use
Set the following parameters: 2.
Allow Tunnel — Select “Yes” to allow tunnel
ventilation or select “No” to put this ventila-
tion mode on standby.
6.5.3. Tunnel Fans
A tunnel fan output starts running when the
room temperature reaches the output’s
“On
Temperature”
; likewise, it stops when the room
temperature falls to its
“Off Temperature”
.
The temperatures at which a tunnel fan starts
and stops are related to the temperature
set point. This mean they are automatically
adjusted when the temperature set point
changes.

Tunnel Fans Following Time Clocks: In the
breeder mode, it is possible for a tunnel fan
output to start running each time a particular
time clock is on. Refer to the “Follow clock”
parameter below to use this function.
