ACCESS CODE
If you want to prevent non-authorised users from changing settings on your climate computer, you can have
your installer set an access code. An access code consists of a combination of 4 digits. You can have a maximum
of 6 access codes set.
A separate access code can be set for the status screen (see page 24).

ROOM
VENTILATION
ROOM VENTILATION
The main thing to prevent is that too much cold air is drawn in abruptly. That is why the room temperature and
the bandwidth have to be set correctly.
Compensations can cause the
calculated value to differ from the
value setting.
If a measuring fan has been
installed, the ventilation measured is
displayed here.
Room temperature
The temperature at which the room ventilation system controls is also referred to as the room temperature. The
required room temperature depends on several factors.
Bandwidth
The bandwidth determines the 'sensitivity' of the control. A short bandwidth will cause the control to react to a
rise in temperature very quickly. That is why a bandwidth of 4 to 7 °C, depending on the outside temperature, is
to be advised.
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 room.
Current temperature
This line displays the current room temperature.
Current ventilation
If room ventilation is controlled using a measuring fan, the measured and calculated ventilation values will be
shown in this line. If the room does not have a measuring fan or if the measuring fan is defective, the calculated
ventilation will be equal to the “measured” ventilation (with step control the ventilation level is adjusted every
30 seconds instead of immediately).
Capacity/Capacity per animal
The calculated ventilation is expressed here in m3/h. The following line will display the calculated ventilation
capacity per animal in m3/h if the fill ratio option has been activated.

Page 12 of 28
Room ventilation options
Number of animals
To be able to express the ventilation
capacity per animal in m3/h, the
climate computer needs to know how many animals there currently are in
the room. Enter the current number of animals at “Number of animals”.
Maximum
Enter the maximum number of animals for which the ventilation capacity
sh
ould be sufficient under normal conditions here.
Fill ratio
As a rule, less ventilation will be required in a room which is not completely filled with animals. E.g. if the room
is filled for only three quarters, the minimum and maximum ventilation values might be lowered by 25% to still
allow optimum ventilation. The fill ratio is calculated on the basis of the maximum number of animals and the
current number of animals in the room.
Every now and then, more animals have to stay in the room or the animals may have to stay in the room longer
than initially planned. In such cases you can lower the maximum number of animals for which the room was
designed, causing the fill ratio to rise to above 100%. This will result in the minimum and maximum ventilation
being increased without you having to adjust other settings.
Minimum and maximum ventilation
The fill ratio is used to calculate the minimum and maximum ventilation capacities. The capacity is shown in
m3/h. If 100% is exceeded, only the minimum ventilation will be adjusted.
Capacity 1st fan / Start 2nd fan / Status of 2nd fan
If your room ventilation consists of 2 fan circuits, “Capacity 1st fan” will list the ventilation capacity of the
1st fan relative to the total ventilation capacity of the 1st and 2nd fans. The fan capacity is entered by the
installer. You should set the percentage at which the 2nd fan circuit is to be switched on in the “Start 2nd fan”
line. This is followed by the current status of the 2nd fan being displayed.
Example: Capacity of 1st fan circuit 4400m3/h, capacity of 2nd fan circuit 5600m3/h
Proportional
The current ventilation of the controlled ventilation circuit is shown on this line.
Step control
If step control is installed, ”Step” will be followed by the step number that is currently active.
Frost protection
Frost protection to prevent the air inlet flaps from freezing and getting stuck.
Capacity of 1st fan circuit =
4400
x 100% = 44%
4400 + 5600

Page 13 of 28
Start outside temperature
Frost protection is activated if the outside temperature drops to below the temperature setting.
Cycle time
Cycle time for frost protection. Frost protection is activated if the outside temperature has dropped to below the
temperature setting and the cycle time (2x cycle time of the flap) has elapsed. The cycle starts again after this.
When the outside temperature has gone up to a higher temperature than the temperature setting again, the
cycle that was started will be finished first.
Flaps
Maximum flap opening
Maximum flap opening when frost protection is active.

Night setting
You can use the night settings to
create a natural temperature
behaviour between day and night by
changing 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 room temperature has to be increased/decreased during this period. Since the ventilation is linked to
the room temperature, the ventilation will also be adjusted during the night time. You can also increase or
decrease the minimum ventilation by an extra percentage value during the night.

Room temperature compensation
The temperature may consist of

the room temperature,

or the outside temperature,

or the inlet temperature, the inlet temperature is measured with
a separate temperature sensor.
The purpose of this compensation is to prevent rapid temperature decreases in a room. The “Maximum
temperature compensation” is used to limit the room temperature corrected by the climate computer. Instead of
the room temperature you can also use the inlet or outside temperatures as the basis for temperature
compensation.
Room ventilation compensation
Bandwidth compensation
This setting is used to adjust the
bandwidth to the current outside
temperature if the outside temperature exceeds the value setting.
Minimum ventilation compensation
The percentage by which the minimum ventilation should be corrected per
°C of change in outside temperature is set in the
“Compens. minimum
ventilation” line (the compensation of the minimum ventilation is a relative
compensation).
Manual mode
You can also set the ventilation percentages for Cleaning and Not in use in
screen “1113 Manual control” in advance. The relevant
settings are copied
as soon as the
Cleaning or Not in use modes become effective for the
room.
Setting the room status to “
Cleaning” and “Not in use” enables you to
manually enter the desired ventilation percentage when cleaning the room
at “Manual contro
l” (percentage setting and calculated percentage are
equal). If the room has determined that the KL
-
61 is on manual operation,
the current status of the room is set to "cleaning" and the potentiometer
position of the KL
-61 is taken over as the calculated m
anual operation (set
value and calculated value are not equal).
Note! The MANUAL CONTROL mode (cleaning) influences the alarm system, only use
this mode if there are NO ANIMALS in the room.
Room ventilation using growth curves
To ensure that the c
limate in the house develops along with the growth of
your animals, the climate computer has growth curves. Depending on the
current day number, the current setting is determined from the curve (if
the curve is
on). A growth curve can consist of a maximum of 7
breakpoints.
Climate settings which are calculated in accordance with a curve are
preceded by the text “Growth curve”. To avoid having to continuously
adjust the curve settings to the animals' behaviour, you can increase or
decrease the calculated cu
rve settings.
Growth curve temperature: this enables you to increase or decrease the calculated room temperature.
Growth curve minimum: this enables you to increase or decrease the minimum ventilation.
Growth curve maximum: this enables you to increase or decrease the maximum ventilation.

Page 15 of 28
Pressing the confirmation key while the cursor is on Growth curve temperature, Growth curve minimum or
Growth curve maximum will display the curve for the relevant settings. You may change the curve settings or
switch off the curve. Press the cancel key to return to the previous window. If you have switched off the curve,
the text 'growth curve' will be replaced by the standard text and you can no longer access the relevant curve
settings from this window (the curve is off).
AIR INLET FLAP 1 / 2
The air inlet flap controls on the basis of the calculated room ventilation.
As soon as the room ventilation exceeds the calculated setting, the air
inlet flap will open on the basis of the temperature, according to the
bandwidth setting.
Example
Room temperature setting 18.0ºC The air inlet flap keeps its preset minimum opening position
of 15% until the room temperature exceeds 21°C (18°C +
3.0°C).
The air inlet flap will be completely open when the room
temperature is 25°C (18°C + 3°C + 4°C).
Air inlet flap temperature setting +3.0ºC
Bandwidth 4.0ºC
Minimum flap opening 15%
Maximum flap opening 100%
Minimum and maximum flap opening
If desired, you can restrict the minimum and maximum flap positions by changing the minimum or maximum
flap opening values.
Current flap opening
This line displays the current flap position.
AIR INLET FLAP 1 / 2 USING GROWTH CURVE
Pressing the confirmation key while the cursor is on
Growth curve
minimum
or Growth curve maximum will display the curve for the
relevant settings. You may change the curve settings or switch off the
curve. Press the cancel key to return to the previous window. If you have
switched off the curve, the text 'growth curve' will be replaced by the
stand
ard text and you can no longer access the relevant curve settings
from this window (the curve is off).
Settings which are calculated in accordance with a curve are preceded by
the “Growth curve” text.
In case of an air inlet flap controlling on the basis of temperature, only the curve settings tell whether the air
inlet flap is controlling on the basis of the room temperature (curve setting less than 10.0ºC) or on the basis of
absolute curve settings (curve setting is 10.0ºC or higher then).

Page 16 of 28
HEATIN
G ROOM HEATING
If there is unnecessarily much
ventilation in an animal house,
unnecessarily much additional
heating will be required as well.
Ensure that the minimum ventilation
setting is not too high and that the
difference between the room
temper
ature and the temperature at
which the heating is switched on is
sufficient.
Temperature setting
The temperature at which the room heating controls is relative to the room temperature, see page 11. You can
set the difference in temperature to the room temperature in this line.
Bandwidth
The bandwidth determines the 'sensitivity' of the heating. The heating is controlled from minimum to maximum
within the bandwidth. A short bandwidth will cause the heating to react to a fall or a rise in temperature very
quickly. This is not good for the climate in the house since it will result in too many ventilation fluctuations.
Maximum heating
You can use the "Maximum heating" setting to limit the maximum level of the controlled heating to a maximum
percentage.
Current temperature
A maximum of 4 temperature sensors can be assigned to the heating control. The current temperature is the
average of these temperature sensors. If a sensor is defective it will be left out of the average calculation and
the heating will continue to control on the basis of the remaining temperature sensors.
Current heating
This line shows the current heating status, On or Off. This line shows also the calculated current status/heating
capacity of the controlled heating. If -0% is calculated for the current heating, the drive signal generated will be
0V instead of the minimum voltage setting. This line is only shown with 0-10V controlled heating.
Growth curve
Pressing the confirmation key while the cursor is on Growth curve temperature will display the room heating
curve. You may change the curve settings or switch off the curve. Press the cancel key to return to the previous
window. If you have switched off the curve, the text 'growth curve' will be replaced by the standard text and
you can no longer access the relevant curve settings from this window (the curve is off).
Running hours
If you change the setting “Clear
running hours” to “yes”, the running
hours of the room heating of the
selected room number will be
cleared.
If the heating is an on/off controlled (not modulating) heating, you can get an overview of the running hours
(heating on time). Beside today's running hours, running hours of the last 7 days and the total number of hours
are shown.

MI
SCELLANEOUS COOLING (ON/OFF)
Setting the cooling is identical to
setting the room heating. To prevent
the humidity in the room from
becoming too high due to cooling,
the RH can switch off the cooling.
If the relative humidity rises to above the preset value + hysteresis, the cooling will be switched off. If the RH
falls to below the preset value afterwards, the cooling will be switched on again. The default hysteresis setting is
2%.
You can use the “Soaking” function when the room status is “out of operation” or “cleaning”. The cooling system
will then be run at full capacity (100%) for the “Period ON” time. As soon as the room status changes, “Soaking”
will be switched “OFF” to prevent the soaking starting immediately after you put the room “out of operation”.
Soaking
Options
Compensation maximum
ventilation
If the current cooling is “on”
(switched on), you can have the
maximum room ventilation lowered
by the percentage set for “Compens.
maximum vent.” to increase the
cooling effect.
TEMPERATURE MONITORING
The temperature monitoring function is activated by your installer.
The current measurement of each sensor is compared with the
measurement of one minute ago.
If the temperature increase in that minute is equal to or greater tha
n the
relative alarm limit, an alarm is given. If the measurement is within the
limits, the previous measurement is made equal to the current
measurement and a new measurement is started.
If the temperature measured by the sensor increases to above the
ab
solute limit, an alarm is given as well.
The temperature monitoring alarm is only given if a positive difference is
detected.
SENSORS
Selecting a sensor displays a table
with the minimum and maximum
sensor temperatures for the past
week. The table also states the times
when the minimum and maximum
temperatures occurred on the
various days.
Your installer can change the sensor names to any name of a maximum of 15 characters.

GROWTH CURVES
You determine the climate settings on the basis of the number of animals
in the room and the animal weight. You set these settings in a curve. The
required temperature will automatically decrease a little then and the
ventilation will automatically increase then after some time. If you remove
a number of a
nimals from a room, while other animals remain behind in
the room, you should not forget to adjust the fill ratio. Otherwise the
minimum ventilation will lead to unnecessary heating and/or too low a
room temperature.
Several curves are available to gradua
lly decrease the target values. A
curve can consist of a maximum of 7 breakpoints.
Growth curves on/off
You can use this setting to switch all curves on or off simultaneously.
Note!

Settings in growth curves of below 10.0ºC are also relative to the room temperature setting.
Do not switch from a relative to an absolute setting within the curve (all settings are below
10.0ºC or all settings are +10.0ºC or higher).
The day numbers in the curve have to be consecutive numbers (see example).
If the day number of the first breakpoint is greater than 1, the setting for the first breakpoint
will be maintained until the preset day number.
If the curve of the setting you want to change is active, you can only change the relevant
setting by changing the setting of the curve.
The settings obtained from a growth curve are recalculated every hour to achieve a more
gradual development of the setting.
Changing the day number clears the room temperature compensation.

ROOM VENTILATION
Room temperature
When changing the room temperature curve you have to consider that some of the curves may be related to the
room temperature.
Copy curve from room
If the climate computer has been set as the main station or if the climate computer forms part of a
communication loop, you can copy the curve of any random room to the current room. The copying may take a
couple of minutes, depending on the number of rooms in the communication loop. If the curve has been copied
successfully, the curve settings, except the On/Off status, will be adjusted automatically. If copying is not
successful, Copying failed will be displayed. You can only copy growth curves of climate computers in the KL-
