put a special attribute. Set the mode of each
tunnel fan output as follows (set the mode to
“—” if nothing applies to an output).
Timer —
The
“Timer”
label identifies a
tunnel fan output that is used in minimum
ventilation. A tunnel fan that has this label
runs according to a timer in minimum venti-
lation and runs continuously when the room
temperature reaches its
“On Temperature”
.
Start tunnel —
The
“Start tunnel”
label indi-
cates the moment at which the transition
from lateral to tunnel ventilation begins: the
first tunnel inlet starts being used at the
start-up of that tunnel fan and the sidewall
vent keeps being used.
Close sidewall —
The
“Close sidewall”
label
indicates the moment at which lateral venti-
lation ends. The sidewall vent closes at the
startup of the chosen tunnel fan and the tun-
nel ventilation mode becomes fully effective
at that moment.
St.tun,clo.side —
The
“Start tunnel, close side-
wall”
label indicates the moment at which
the controller switches from lateral to tun-
nel ventilation. With this option, there is no
gradual transition made from one ventilation
mode to the other. The sidewall vents close
and the tunnel inlet start being used at the
startup of the chosen tunnel fan.
Start tunnel 2 —
The second tunnel inlet
starts being used at the startup of the se-
lected tunnel fan output.
Fan Shutoff Column:
Fan Shutoff —
The controller can disable
some lateral fans at the startup of chosen
tunnel fan outputs. Select the moment at
which each lateral fan must stop (if appli-
cable). Note that when a fan is stopped, it
will not restart until the controller re-enters
in lateral ventilation.
If you want the selected fan to run when

a particular time clock output is on, select
the
“Follow Clock”
tab with the menu selec-
tors and then set parameters below.

tab is only accessible if the controller is used in a
breeder facility.

Follow clock —
Select during the operation
of which time clock output you want the
selected tunnel fan to run.
Low stop T° —
The selected tunnel fan will
stop following the time clock output if the
room temperature gets too low. Set this se-
curity limit to the desired value.
Tunnel Inlets
6.5.4.
The controller can control the opening of
2 tunnel inlets. These inlets either operate as
a function of the static pressure level or as a
function of temperature. Refer to the Set-up
menu in section 4.4 to enable the tunnel inlets
and to choose their operating mode.
If 2 tunnel inlets are used, they both follows
the same movements. However, both tunnel
inlets do not start being used at the same time.
The 1
st
inlet starts being used at the beginning
of tunnel ventilation and the 2
nd
inlet starts at
the startup of another user-defined tunnel fan
output. Refer to the previous section of this
manual to set the moment at which the 2
nd
tunnel inlet starts being used.
6.5.4.1.
Temperature-based Tun-
nel Inlet
When using temperature-based tunnel inlets,
the user must associate an actuator position
with the startup of each tunnel fan. This
way, when a fan/tunnel fan starts, the inlet
opens accordingly. The tunnel inlet starts
opening this way at the beginning of tunnel
ventilation. The graph below shows how the
tunnel inlet opens. Refer to Set-up menu in
section 4.4 to enable a temperature-based
tunnel inlet.
Pre-opening of the Tunnel Inlet:
At the be-
ginning of tunnel ventilation, the controller
waits for the tunnel inlet to reach half of
its programmed position before activating
the fans (or waits 30 seconds, whichever
is shorter).

* * Tunnel Opening
* 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’s
operating mode is set to “T°” in the Set-up menu
(see section 4.4).

Tun #x Opening —
Associate a tunnel inlet
opening (in %) with the startup of each tun-
nel fan.
If a tunnel fan is used in lateral ventila-
tion, set its tunnel inlet opening to 0% if
you don’t want the tunnel inlet to open
in lateral ventilation!
Total opening time —
Specify the exact time
that is required to reach the actuator’s maxi-
mum limit switch. The controller will limit the
opening of the inlet according to this value.
*
This parameter is common to all programs.
6.5.4.2.
Pressure-based
Tunnel Inlets
Opening of the Tunnel Inlet:
If the tunnel inlets are controlled by static
pressure, the first inlet start moving accord-
ing to the fluctuations in the pressure level
when the controller enters in tunnel ventila-
tion. It open when the pressure level exceeds
the high pressure limit and closes when the
pressure level gets lower than the low pres-
