6.1.4. Min Ventilation Curve

A curve is made of 10 steps. Each step speci-
fies a day number and a minimum ventilation
speed for that day (the day number refers to
the animal age). When the curve is activated,
the controller changes the minimum ventila-
tion speed every hour in a linear fashion
between consecutive steps of the curve.
When the last step is reached, the controller
keeps using the speed associated to that day.

Notes: Certain restrictions apply to reduce
the risk of errors:
1. The highest possible day number is 365.
2. Decreasing day numbers are not allowed
3. Decreasing min speeds are not allowed.
4. All ten steps must be specified. If you
don't need 10 different steps, repeat the
last speed for each unnecessary step.
Refer to section 4.2 on page 10
to set the current day number.

Curve status — Select "Yes" to enable
the curve (or "No" to disable it). Once the
curve is on, the controller automatically
adjusts the set point between consecu-
tive points of the curve; for this reason,
curve steps cannot be modified while the
curve is running.
If all curves are disabled (Min.Vent,
Set Point & 0-10V Heat curves), the
controller will automatically set the day
number back to 1 day when a curve
is being activated.
The parameters below can only be
modified while the curve is off.
Day numbers — Set the day at which each
curve step starts.
Min Spd — Assign a minimum speed to each
step of the curve.
