MINIMUM VENTILATION SPEED CURVE
The user can define a minimum ventilation curve to adjust the minimum
speed on both variable outputs automatically over a given time period.
Each curve is defined by ten points. Each point specifies the day number
and minimum speed for that day. The herd age value defines the current
day number used by the curve. Once the points are defined, the mini-
mum ventilation curve must be activated. When the minimum ventilation
curve is activated, the controller adjusts the minimum speed every hour
in a linear fashion between two consecutive points.*
Specifying Minimum Ventilation Curve
Set the function to MINIMUM
VENTILATION / CURVE
using the
menu select buttons. The current
minimum speeds and curve on/off
state are displayed.
Press the down-arrow key twice.
The day number and minimum
speed for the first curve point are
displayed.
Press the Edit key as required to adjust each parameter in turn.
When a parameter flashes, it can be adjusted using the arrow keys.
Set the speed to OFF to deactivate an output.
Press the down-arrow key to display and adjust the other points of
the curve.
NOTE: All ten points of the curve must be specified. If you don't need
ten different points, repeat your last minimum speed for each unneces-
sary point of the curve.
* This does not hold if the speed on an output is set to OFF at some points in
the curve. In this case, the speed of the preceding point will be used right up
to OFF point. Similarly, the output will remain deactivated following the OFF
point right up to the next point.
