Temperature Curve Program 1
Use to navigate
The following parameters can only be
modified while the curve is off.
If the curve is running, it is still possible
to adjust the set point value of all curve
steps simultaneously with the curve
offset parameter (see sec. 5.3.3).
2. Set the following parameters:
Current day —
This is the current age of the
animals. This value may be changed to move
backward or forward on the curve. A change
in the current day also changes the animal
age in the “Age & mortality” menu.
Set point —
The day set point is displayed.
Day numbers —
Set the day at which each
step starts. The day number refers to the
animal age. It is adjustable from -5 to 450
days. Negative values are used to prepare
the house before letting the animals enter.
*
This parameter can only be modified while the
curve is disabled.
Temperature set points —
Assign a temperature
set point to each step of the curve. *
This param-
eter can only be modified while the curve is disabled or
with the curve offset function (sec. 5.3.3).
Status —
Select
“Yes”
to activate the curve.
Once the curve is on, the controller auto-
matically adjusts the set point automatically
between consecutive points of the curve; for
this reason, curve steps cannot be modified
while the curve is running.
5.3. Temperature Curve
5.3.1. Principle of Operation
A curve is composed of 10 steps. Each step
specifies a day number and a temperature set
point for that day (the day number refers to
the animal age). Once the curve is activated,
the controller changes the set point every
hour in a linear fashion between consecutive
steps of the curve. When the last step is
reached, the controller keeps using the tem-
perature set point associated to that day.

Notes
Certain restrictions apply to reduce the
risk of errors:
1. The highest possible day number is 450.
2. Decreasing day numbers is not allowed.
3. All ten steps must be specified. If you don’t
need ten different steps, repeat the last tem-
perature for each unnecessary step.
5.3.3. Modifying Curve Points
You can adjust the temperature set point as-
sociated to all curve points while the curve
is running.

Temperature curve offset —
Select the

curve (+/- 10°F). *
This parameter is accessible if
the temperature curve is currently running.
