4 Calibration
4.1 Calibration of Air Intake and Air Outlet
The controller must be adapted to the winch motor after installation.
Winch motors with feedback must be calibrated by a technician, while winch motors without feedback are cali-
brated automatically once the technician has set up a time for Air inlet time.
During the automatic calibration, the air inlets/air outlets open and close completely for a short time and then re-
turn to the position which the controller calculates.
The change-over switch on the winch motor must be se to AUT.
4.1.1 Winch motor without feedback
Time
Setting of the time of day when the automatic calibration shall run.
Running time
Setting of the time it takes to run from fully open to fully closed.
Runs before recalibra-
tion
Setting of the number of times the inlet flap has to run before it calibrates automati-
cally.
Minimum voltage
Maximum voltage
When the air inlets or air outlets are 0-10 V controlled, the output voltage can be ad-
justed via
Min. voltage
and
Max. voltage.
1. Select the menu
Technical | Calibration | Climate | Side inlets | Calibration
.
2. Select
ON
to start calibration.
3. Check that the correct inlet(s) open(s) and close(s) correctly.
4. Wait until the calibration is finished and the display shows
Calibration ended
again.
Calibration of other air inlets and air outlets are carried out in the same way.
4.2 Calibration of climate sensors
Temperature and humidity
The connected temperature and humidity sensors can be calibrated using an offset.
If, in connection with manual measurements, the current value is measured to a level that differs from the regis-
trations provided by the installed sensors, you can adjust the read-out value so that it corresponds to your ob-
servation.
0-10V sensors
Adapt the controller to the sensors after installation.
When a sensor is 0-10 V controlled, you can adjust the output voltage via
Minimum voltage
and
Maximum volt-
age
.
When
Min. value
and
Max. value
are set, you should also indicate the range within which the sensor can mea-
sure.
4.2.1 Calibration of Weather Station
Rear end offset from north
Set the number of degrees that the geographical location of the live-
stock house deviates from a northerly direction.
Wind direction minimum voltage
Adjust the voltage via Minimum voltage and Maximum voltage.
