In addition to the ventilation control which controls on the basis of temperature, the further functionality of the
poultry computer includes the possibility of controlling the ventilation/flap position on the basis of relative
humidity or CO
2
. This means that the ventilation effort will be increased if the result measured is higher than the
“compensation start” setting.
Δ
RH * RH compensation factor
Δ
RH = current RH – RH-compensation start.
If 0.0 is set, this means that RH compensation
does not affect the ventilation and/or the flap
position. If 9.9 is set, RH compensation has a
maximum effect on the ventilation and/or the
flap position.
The corrected ventilation is limited by the pre-set
maximum.
RH-compensation Compensation ventilation/flap position
Absolute
Compensation = (current RH – RH-compensation start) * RH-compensation factor
Relative
Compensation = (current RH – RH-compensation start) * RH-compensation factor *
(calculated ventilation / 100)

Fan control:
10+12 = 22%
10+1.2=11.2%
CO

compensation is calculated in accordance with the RH compensation (considering that 100ppm is equal to
1.0% ventilation change).
If both RH compensation and CO
2
compensation are active, the highest compensation value is used for
ventilation correction.
Before cleaning the room, remove the HR sensor and CO2 sensor and screw
the protection cap onto the extension cables.
