VENTILATION GROUPS
The number of menu options in the “Ventilation groups” menu varies, depending on the type and the number of
ventilation groups.
Please note that the text displayed for the ventilation groups can differ from the text shown in this manual (the
text can be changed by the installer, except the texts for the main ventilation group).
CURRENT VENTILATION CAPACITY
The total calculated ventilation capacity and the ventilation capacity per animal are expressed here in m
3
/h. The
total ventilation capacity of the house consists of the capacity of the auxiliary ventilation group and the total
capacity of the main ventilation group (capacity of the 1
st
, 2
nd
, 3
rd
fan and the step control).
MAIN VENTILATION
The group which controls the “main ventilation” in the house. Compensations can cause the calculated value to
differ from the value setting.
TEMPERATURE SETTING
The temperature on which the main ventilation group controls; this setting is relative to the house temperature.
The calculated temperature on the basis of which the ventilation group controls is shown behind the
temperature setting.
BANDWIDTH
Determines the 'sensitivity' of the fan to react on a temperature change. A short bandwidth will cause the fan to
react to temperature change very quickly. This is not good for the climate in the house (also see 'Automatic
bandwidth compensation' on page 18).
MINIMUM AND MAXIMUM VENTILATION
If compensation depending on the fill ratio has been installed, the minimum and/or maximum ventilation will be
adjusted to the number of animals in the house. In addition, the minimum and maximum ventilation can be
affected by the RH, CO
2
, meteo, night settings and outside temperature.
CURRENT TEMPERATURE
The current house temperature is displayed.
CURRENT VENTILATION
If house ventilation is controlled using a measuring fan, the measured and calculated ventilation values will be
shown in this line. If the fans do not have measuring fans or if a measuring fan is defective, the calculated
ventilation will be equal to the “measured” ventilation.
The current ventilation is calculated on the basis of the bandwidth and the minimum and maximum ventilation
settings.
CAPACITY
The calculated ventilation is expressed here (total and per animal).
MAIN VENTILATION USING GROWTH CURVES
Climate settings, which are calculated in accordance with a curve, are
preceded by the text “Growth curve”.
The behavior of the animals shows the quality of the climate. To avoid
having to continuously adjust the curve settings to the animal’s behavior,
you can increase or decrease the calculated curve settings of the first
column (+0.0°C/+0.0%).
Growth curve temperature:
to increase or decrease the calculated house temperature.
Growth curve minimum:
to increase or decrease the minimum ventilation.
Growth curve maximum:
to increase or decrease the maximum ventilation.
