IMPORTANT
NOTES CONCERNING THE ALARM SYSTEM
Where climatic control is used in livestock buildings, breakdowns, malfunctions or faulty settings may cause
substantial damage and financial losses. It is therefore essential to install a separate, independent alarm system
which monitors the house concurrently with the climate and production controller. According to EU directives
98/58/EU an alarm system must be installed in any house that is mechanically ventilated.
Please note that the product liability clause of SKOV A/S’ general terms and conditions of sale and delivery
specifies that an alarm system must be installed.
In case of operating error or improper use, ventilation systems can result in production loss or
cause loss of lives among animals.
SKOV A/S recommend that ventilation systems should be mounted, operated and serviced only
by trained staff and that a separate emergency opening unit and an alarm system be installed as
well as maintained and tested at regular intervals, according to SKOV A/S’ terms and conditions
of sale and delivery.
Qualified personnel must perform installation, service and fault-finding of all electrical
equipment in accordance with the applicable national and international standard EN 60204-1 and
any other EU standards that are applicable in Europe.
The installation of a power supply isolator is required for each motor and power supply to
facilitate voltage-free work on the electrical equipment. SKOV A/S does not supply the power
supply isolator.

Natural Ventilation
2.1 Pure Natural Ventilation
Using Natural ventilation, the air change happens when air currents move between the adjustable air inlet and
the air outlet without any assistance of fans. Curtain openings on the sides of the livestock house are typically
used as both air inlet and the air outlet. You can also use tunnel opening, open flap in exhaust unit or ridge
opening as air outlet. The mechanical regulation is solely opening and closing of the inlets and outlets. Since no
exhaustion takes place by means of fans, an energy saving is achieved and the noise level in the livestock house
is reduced.
Figure 1: Example of a naturally ventilated livestock house with curtain openings on the sides of the house and
ridge opening in the roof
2.2 Natural Ventilation in Combination
Natural ventilation can be combined with other ventilation principles (LPV, Tunnel and heat recovery)
depending on how the ventilation system is constructed. When the required climate can no longer be sustained
using natural ventilation, the ventilation system switches to a different ventilation principle, for instance based
on too high or low outside temperature, too high CO2level in the livestock house or too high wind velocities.

Minimum ventilation
natural
Setting in per cent of air inlet and air outlet opening. Lower limit for how little opening
you can have in Natural ventilation mode.
When Minimum ventilation natural is set to a value exceeding zero, the air inlet and air
outlet cannot close completely.
At batch production, the value follows a batch curve (Operation/ Batch curves/ Climate).
See the user manual supplied with the controller for a description of batch curves and
user offset.
Climate/ Ventilation/ Minimum ventilation setpoints / Reduced minimum ventilation
The function is intended for houses that require a better indoor temperature at the cost of accepting a slightly
poorer air quality. This may be necessary when it is extremely cold outside and the heating system cannot
provide sufficient heating.
Start at outside
temperature
Setting the outside temperature that will activate a reduction of the minimum
ventilation.
Max reduction at
outside temperature
Setting the outside temperature where the minimum ventilation is not further reduced.
See also section 9.
This function is an alternative to reducing the minimum ventilation via a CO2 sensor. However, this function
will take precedence if CO2 minimum ventilation is also used.

Example 1: Natural ventilation is active dependent on the current outside temperature
Outside temp. Temp. setpoint
High outside
temperature offset
Setting of a number of degrees added to the temperature setpoint to establish an upper
limit for the outside temperature. When outside temperature is above limit, ventilation
switches from Natural ventilation.
By changing this offset, you change the high temperature which starts and stops Natural
ventilation. Make the setting higher to switch to Natural ventilation at a higher
temperature.
High outside
temperature:hysteresis
Setting of a number of degrees which postpones the switch to Natural ventilation at
decreasing temperature. This makes regulation more stable so it does not constantly
switch between the various ventilation principles.
Low outside
temperature offset
Setting of a number of degrees subtracted from the temperature setpoint to establish a
lower limit for the outside temperature. When outside temperature is below limit,
ventilation switches from Natural ventilation. Make the setting higher to switch from
Natural ventilation at a lower temperature.
