TEMPERATURE SET- 5.
TINGS
5.1. Temperature Set Point
The set point is a target temperature in
the room. The activation of most outputs
of the controller is based on this reference
temperature.

Set the following parameters: 2.
Set point settings are common to all
programs of the controller.
Current set point — This is the current tem-
perature set point in use. This value cannot
be changed; to modify the set point, change
the day or night set points below.
Day set point — Set the temperature set point
that is used during the day (this set point is
used all day long if the night set point is not
enabled). The controller can also change the
day set point automatically over time by us-
ing a curve (see section 5.2). *
This parameter
can only be modified while the temperature curve is
inactive (sec. 5.2).
Night set point — A different temperature
set point can be used at night. The night set
point can be used to lower the target room
temperature for instance. The night set point
is relative to the day set point, which means
that it is automatically adjusted when the day
set point changes. Set the night set point to
the desired value. *
Accessible if the night set point
is enabled (see section 4.10).
Clean mode set point — Select what is the
target room temperature while the controller
operates in clean mode.
Outside set point — The controller can adjust
the moving speed of natural ventilation cur-
tains as a function of outside temperature.
When this function is used, the controller
refers to the outside temperature set point
to control the moving speed. Set the outside
temperature to the desired value. *
Accessible if
the outside temperature sensor is enabled in section
4.7.1 and if the curtain compensation is enabled in
the Installation Setup (section 4.5).
5.2. Temperature Curve
Principle of Operation 5.2.1.
The controller can automatically adjust the
target room temperature (day set point) over
time by using a curve.
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.

Decreasing day numbers is not allowed. 4.
All ten steps must be specified. If you don’t 5.
need ten different steps, repeat the last tem-
perature for each unnecessary step.

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. 5.2.3).
Set the following parameters: 2.
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
by using the curve offset function (sec. 6.1.3).
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.
