Explanation control functions
OptiSec = Optimum Setpoint Control
The control computer uses a neutral zone, with minimum ventilation and no heating. This lowers energy costs.
The neutral zone is the area between control value heating and start temperature ventilation. If OptiSec is not
used, the control value heating is lower than setpoint house temperature. With very young animals the actual
house temperature can be lower than the setpoint house temperature.
Figure 7: Example OptiSec: The control computer has brought the setpoint heating (was 20°C) closer to the
setpoint house temperature (22°C)
The figure shows that the control computer brings the setpoint heating (was 20°C) closer to the setpoint house
temperature (22°C).
OptiSec brings the control value heating closer ( ) to the setpoint house temperature, if the actual house
temperature is lower than setpoint house temperature. This means the heating will activate earlier and the
difference between the actual and required house temperature will be smaller.
The control computer regularly checks the house temperature. If this is below the setpoint house temperature, the
offset heating will be gradually lowered. At the same time it increases the Offset start ventilation. This shifts the
neutral zone.
The control computer can increase the setpoint heating until this equals the setpoint house temperature. The
maximum correction can be limited using Band, (tab page OptiSec).
If the actual house temperature rises above the setpoint house temperature, the OptiSec-correction will be
gradually decreased. This means that setpoint heating and Start temperature ventilation will return to their original
settings. These setpoints will not drop any further. The control computer does not use the OptiSec-settings in
reverse — the offset Start temperature ventilation will not be decreased further than the original value.
