6.3. Lateral Ventilation
Lateral ventilation can only be used if
at least 1 fan output is enabled in the
Set-up menu (see section 4.4).
Lateral Ventilation Fans
6.3.1.
Lateral ventilation begins at the startup of
the first fan stage and ends at the startup of
the ventilation mode that follows (i.e natural
or tunnel ventilation).
A fan output starts running when the room
temperature reaches its
“On Temperature”
;
likewise, it stops when the room temperature
falls to its
“Off Temperature”
.
The temperatures at which a fan starts and
stops are related to the temperature set point.
This mean they are automatically adjusted
when the temperature set point changes.

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

Main menu
* On / Off Settings
* A password may be required to access this menu
(see section 4.2.1).
Use the arrow keys to scroll down and select

the desired fan output.
* These outputs are avail-
able if they have previously been enabled in the Set-up
menu (see section 4.4).

Set the following parameters:

On & Off Columns:
Temperatures —
Set the room temperature
at which each fan starts and below which it
stops. Note that the first fan to start signals
the end of minimum ventilation and the begin-
ning of lateral ventilation. *
Note that the “On
Temperature” of a fan must be greater than its “Off
Temperature”.
Mode Column:
This column tells the controller to execute
a particular function at the startup of a fan
output or allows giving the output a special
attribute. Set the mode of each fan output
as follows (set the mode to “—” if nothing
applies to an output).
Timer —
The
“Timer”
label identifies a fan
output that is used in minimum ventilation.
A fan output that is labeled
“Timer”
runs
according to a timer in minimum ventilation
and runs continuously when the room tem-
perature reaches its
“On Temperature”
.
Close Attic —
The controller can close the at-
tic vent at the startup of a certain fan output.
Assign the
“Close attic”
label to the fan output
at which the attic must close (if applicable).
*
This option is available if the attic vent is enabled
in the Set-up menu (see section 4.4).
Timer, Close Attic —
Use this label to identify
a fan that is used in minimum ventilation and
whose startup asks for the attic vent to close.
*
This option is available if the attic vent is enabled
in the Set-up menu (see section 4.4).
If you want the selected fan to run when
4.
a particular time clock output is on, select
the
“Follow Clock”
tab with the menu selec-
tors and then set parameters below.
*This
tab is only accessible if the controller is used in a
breeder facility.

selected fan to run.
Low stop T° —
If the room temperature gets
too low, the fan stops following the time
clock output. Set this security limit to the
desired value.
Air Intake in Lateral Vent.
6.3.2.
Two vent outputs can be used in lateral ven-
tilation: a sidewall vent and an attic vent.
Both of these vents move according to the
variations in the static pressure level: they
opens when the pressure level exceeds the
sidewall vent’s Hi pressure limit and close
when the pressure level gets lower than the
sidewall vent’s Lo pressure limit.
Automatic adjustment of the pressure limits
as a function of the outside temperature:
If an outside temperature sensor is used,
the controller can automatically adjust the
static pressure limits used by sidewall vents
according to the outside temperature. Using
higher pressure limits in cold weather allows
reducing the cold air intake since the pressure
level has to be higher before the vents start
opening. Likewise, using lower pressure limits
in warm weather allows the vents to move
with fewer restrictions.
