6.2. Minimum Ventilation
Minimum ventilation cycles are activated
when the room temperature is lower than the
start temperature of the first fan stage. Run-
ning the fans even though ventilation is not
required for reducing 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 can only be used
if at least 1 fan output is enabled in the
Set-up menu (see section 4.4).
Minimum Ventilation Timer 6.2.1.
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 com-
mon to all programs of the controller.

Ventilation Timer
Automatic adjustment of the minimum venti-
lation timer as a function of relative humidity:
The controller can automatically increase the
“On Time”
portion of the minimum ventilation
timer as the humidity level increases. Refer
to section 12.1 for further information about
this RH compensation function.
The controller can automatically extend
the cycle time in order to pre-open the
vents.

The minimum ventilation timer is displayed
along with the

Minimum ventilation
ON TIME
On Time — Set the “On Time” of the minimum
ventilation timer. Note that if the minimum
ventilation ramp is enabled, the controller
automatically defines this value as a function
of the animal age (see section 6.2.2).
Cycle — Set the cycle time of the minimum
ventilation timer. Note that the cycle time
must be longer than the
“On Time” .
Night On — Set the “On Time” of the minimum
ventilation night timer. If the “On Time Ramping”
function is used, the controller automatically
defines this value as a function of animal age.
6.2.2. Min Ventilation Timer Ramp
The controller can automatically adjust the
“On Time” portion of the minimum ventilation
timer with time. The minimum ventilation
ramp is composed of 12 steps and each step
associates an
On Time with an animal age.
Once the ramp is enabled, the controller
changes
“On Time” portion of the minimum
ventilation cycles every hour in a linear fash-
ion between consecutive steps of the ramp.
When it reaches the last step, the controller
keeps using the last
“On Time” until the end
of the flock.
Night Ramp: The minimum ventilation ramp
can be configured differently for nighttime.
Refer to the Set-up menu to enable or disable
the night settings (see section 4.4).
Select: 1.
Main menu
* Minimum Ventilation
Ramping
* A password may be required to access this menu
(see section 4.2.1).
Set the following parameters. 2. *The param-
eters below are common to all programs.
Ramping Status — This is the status of the
minimum ventilation ramp. Select
“On”
to
enable it or select
“Off”
to disable it.
Age — Set the age at which each step starts.
This parameter ranges from -5 to 450 days
(negative values are used to prepare the
house before letting the animals in).
On — Assign a minimum ventilation “On Time”
with each step of the ramp. If you don’t need
12 different steps, repeat the last
“On Time”
for each unnecessary step.
Night On — If a different night ramp is used,
assign a night “On Time” for each step of the
curve. If you don’t need 12 different steps,
repeat the last
“On Time” for each unneces-
sary step. * This parameter is accessible if the
“Night Min. Vent.” option is enabled in the Set-up
menu (see section 4.4).
Minimum Ventilation Fans 6.2.3.
Fan Selection 6.2.3.1.
The minimum ventilation cycles are ensured
by a user-defined selection of fans and/or
tunnel fans. In order to identify a fan/tunnel
fan that is used in minimum ventilation, set
its operating mode to
“Timer” or “Tmr, clo at-
tic” in the “On/Off Settings” menu. Refer to the
lateral or tunnel fan sections of this manual to
assign these fan operating modes (sections
6.5.1 & 6.5.3).
6.2.3.2. Fan Cycling
In minimum ventilation, the controller can
make a rotation of the fans selection between
consecutive cycles. This rotation allows run-
ning the fan motors evenly and regularly. In
order to use fan cycling, you must specify
how many fans must be activated simulta-
neously and specify after how many cycles
they must switch.
Here is an example of fan cycling with 4 fans.
In this example 2 fans are used simultane-
ously and a switch is made every 3 cycles:
