5.15.2 Setting the Minimum Ventilation Curve
Fans' On-Time, in minimum ventilation, can automatically be adjusted
over a given period of time, by using the minimum ventilation curve.
The On-Time changes using 10 steps. Each step specifies a day number and
an On-Time value for that day. The animal age defines the current day
number used by the curve. Once the 10 steps are defined, the curve must
then be activated. The controller changes the On-Time, in minimum
ventilation, every hour in a linear fashion between consecutive steps of the
ramping curve. When the last step is reached, the fans' On-Time for that
day is maintained until the animal age is set back to Off.
NOTES:
i) All ten points of the curve must be specified. If ten points are not
needed, repeat the last On-Time value for each unnecessary point.
ii) Certain restrictions apply to reduce the risk of errors:
- The highest possible day number is 450.
- Decreasing day numbers are not allowed.
- Decreasing On-Times are not allowed.
