Night setting
You can use the night settings to create natural temperature behaviour between day and night by reducing the
temperature setting by a couple of degrees during the night.
In addition to the period when the night setting has to be active, you can also set the number of degrees by
which the house temperature has to be increased/decreased during this period. Since the ventilation is linked to
the house temperature, the ventilation will also be adjusted during the night. You can also set the percentage by
which the minimum ventilation is to be increased/decreased during the night. Note! The compensation of the
minimum ventilation is a percentage of the minimum ventilation.
Night setting house temperature: 20.0°C
-1.0
= 19.0°C
Night setting minimum ventilation:
-20%
of 10% = -2% => 10%-2% = 8%
Temperature
The animals may fall ill due to rapid temperature drops, which usually occur in the spring and autumn. To
prevent these rapid temperature drops you must activate the temperature compensation. Temperature
compensation will limit the house temperature corrected by the control. The ‘Reduce temp. compensation’
setting determines the speed at which the corrected house temperature is controlled down to the preset house
temperature in the event of a drop in temperature. If the user has set a maximum temperature compensation of
0.0 ºC, the temperature compensation is switched off.
Example
:
Temperature exceeded
= Current house temperature - (House temperature s bandwidth)
= 28.1 ºC - (20 ºC + 4.0 ºC) = 4.1 ºC
However, the temperature correction can never be more than the
maximum temperature compensation. This means that in the above
example it can never be more than 3.0ºC (maximum setting)
instead of 4.1 ºC (calculated excess value). The corrected
temperature setting becomes equal to: house temperature s
temperature correction = 20.0 ºC + 3.0 ºC = 23.0 ºC.
In this example, the time in which the house temperature is
controlled back to the temperature setting is:
(House temperature correction / max. temperature compensation) x
1 hour => (3.0ºC / 0.2 ºC) x 1 hour = 15 hours.
Ventilation
As a rule, less ventilation will be required in a house which is not completely filled with animals. E.g. if the house
is filled for only 95%, the minimum and maximum ventilation values might be lowered by 5% (of the preset
value) to still allow optimum ventilation. The fill ratio is calculated on the basis of the maximum number of
animals in the house and the current number of animals in the house.
