6.1.4. Min Ventilation Curve

A curve is composed of 10 steps. Each step
specifi es a day number and a minimum ven-
tilation speed for that day (the day number
refers to the animal age). When the curve is
activated, the controller changes the mini-
mum ventilation 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 450.
2. Decreasing day numbers are not allowed
3. All ten steps must be specifi ed. If you
don't need 10 different steps, repeat the last
speed for each unnecessary step.
Note that the minimum ventilation curve
must be turned off to adjust the curve
steps (fan speed & days). Use the down-
arrow key to scroll each point of the
curve. The curve status fl ashes on the
display. Press the Edit key then press the
down-arrow key to turn it Off.
