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.
