Before installing and commissioning the Aura 14, read the safety instructions, provisions and conditions carefully.
This paragraph contains a number of general safety instructions. The installation of the device and remedying of
any malfunctions should be performed by a certified electrical installer according to the applicable norms. The
guarantee does not apply if this product is installed in any other way than is indicated by Fancom and if the
product's motor has been opened and changes have been made to the product.
Disconnect power before installation or before carrying out any maintenance to the control computer.
You must be able to switch off the device using a bipolar main switch.
Take precautions against electrostatic discharge (ESD) when working on the control computer. Ensure
the workplace is clean and dry.
Use the wiring/cables indicated on the connection diagrams and follow all. Only apply power after the
wiring has been connected correctly. Incorrect connections can cause permanent damage. Before a
new fuse is placed, the cause of the defect should be remedied by an authorized installer. Only replace
a defective fuse by a fuse of the same type (see connection diagram).
Inspect the control computer regularly for any damage. Report any damage to your installer
immediately. A damaged control computer is dangerous! Do not use running water (high pressure
cleaners) to clean your control computer. The control computer is water resistant, but not waterproof!
Do not switch off the computer when houses are unoccupied; otherwise there is the risk of
condensation in the computer.
The installation, of which this product is a part, must be equipped with a reliable, independent alarm
system, for example, a minimum/maximum thermostat. We advise you to test the alarm system every
day for proper functioning.
If the product is part of a climate control system, the oxygen levels in the areas being controlled must
always be maintained under all circumstances - even in emergency situations. We advise you to use an
emergency system (emergency power supply unit, emergency opening systems, option for manual
operation) to guarantee the oxygen levels. This system must be regularly tested for proper functioning.
The control computer is a piece of electronic apparatus. There is always a risk of a malfunction
occurring. Fancom has made every effort to ensure that an alarm is given in the event of an emergency.
Unfortunately, a 100% guaranteed cannot be provided as not all circumstances are under Fancom
control. Fancom cannot be held liable for any damage caused by incorrect settings and/or non or partial
functioning of the entire installation. Ask your installer if the alarm outputs of each control computer
have been connected to a separate alarm circuit.
Connect each Fancom device according to the applicable legislation/regulations of the local energy
provider.
Check that the mains voltage and frequency, for which this computer is suitable, correspond to the
mains voltage and frequency on site.
Low-voltage and high-voltage wires may not be placed parallel to each other but may cross each other.
When using metal ducts, Fancom advises grounding the ducts at the ends and at as many other places
as possible.
Connect the computers to one group, from the main distributor.
Keep signal and power cables as short as possible.

This chapter describes the main parts and the operation of the Aura 14.
The Aura 14 can be operated on the touch screen.
1. Touch screen
The Aura 14 screens are divided in three sections:
1. Title bar: Displays the name of the selected screen (e.g. Overview), the actual day number (based on the
curve), the date and time and provides access to right fly-over menu (installation and user menu).
2. Working area: Displays the data of user or installation settings of the control computer.
3. Menu selection and alarm bar: Provides buttons to navigate through available menus (e.g. curve) and an
alarm indicator to navigate to more details.

With daily management you can set the temperature and ventilation settings manually. If a curve is used, the daily
management overwrites the settings temporary.
The left dial displays the actual temperature. The right dial displays the actual ventilation. In both dials the actual
control value is displayed as a red marker. The highlighted green area displays the lower boundary comfort zone
(related to setpoint heating) and the upper boundary comfort zone (related to max diff alarm). The actual status
will light up:
: Heating active
: Thermal control (used as cooling)
: Number of additional fans in use
Use the dials as follows:
1. Tap the dial you want to set. A pop up of the dial appears:
2. Set the value by tapping :
Tap to increase or decrease the value step by step.
Hold the to quickly increase or decrease the value.
3. Tap to confirm or to cancel all the settings in the popup window.

The day number is a counter increased by the controller each day at midnight by one up to a maximum
of 999. If the day number is 0 it will not change. The Aura 14 then controls without the curve, even if the
bending points have been set.
If a curve is used, the day number is the basis used to calculate the setpoints from the relevant curve. If
a negative day number is set, the Aura 14 will control without using the curve, until the day number is a
positive number. A negative day number is also increased at midnight by one, except the jump from day
–1 to day +1 (a jump of 2).
There are 10 bending points. At a bending point start by entering the day number; the settings at this bending
point apply to this day number.

Request the alarm overview using the alarm button .
There are two buttons:
1. Alarm overview to readout the status.
2. Alarm settings to change the alarm settings.
Types of alarm
There are two types of alarm:
1. LOUD: A loud alarm means a report is shown on the screen and a siren is sounded (if connected). Take
action immediately.
2. SILENT: With a silent alarm (warning), a report will appear on the screen. This type of alarm is usually less
serious. An active process can be stopped, if required.
With both types an alarm message will appear on the screen.
Alarms can be set to LOUD or SILENT, if required. For nearly all the alarms the user decides the limits outside
which alarms must be given.
Status
Readout / setting the alarm status:
Alarm stand by: no alarm (stand by mode).
Alarm test: test the alarm and after reset the status will be changed to Alarm
stand by.
Alarm recovered: there was an alarm which has been recovered. The controller
switches off the alarm, but the alarm status remains visible.
Silent alarm: alarm message shown on display only.
Alarm temp. off: switch off the current alarm. When the alarm situation has been
cancelled, this status will automatically become Alarm stand by. Always check
that the status has reverted to Alarm stand by.
Alarm disabled: switch off the alarm entirely. Only do this when houses are
unoccupied. Do not forget to reset the status to Alarm stand by.
Alarm: the type of alarm is shown on the display.

An alarm will occur if a temperature becomes higher than the maximum
alarm limit: 20 + 4 + 3 = 27°C.
On hot summer days the temperature in a section can be very high. This
can result in a maximum alarm or the difference alarm will have to be set
high. This is not desirable with lower temperatures; the maximum alarm
limit would then be unnecessarily high. In order to provide effective alarms
(max. difference alarm as small as possible) the computer increases the
alarm limit parallel to the outside temperature, as soon as this is higher than
the point at which ventilation is maximum.

Setting of the time length (hours and minutes) after which the control computer can
give an alarm. During this period of time the control computer cannot give an alarm
e.g. to prevent an alarm is giving during the warming up period.
Warming up the section. A section has to be warmed up from 10ºC to
20ºC. This should take approximately five hours. Set the temperature
required and the time to 05:00 hours. After five hours, when the section
should have reached the correct temperature, the alarm will automatically
become active.
Large temperature jump in a farrowing pen. In a farrowing pen the
temperature has to increase from 19ºC to 24ºC. This should take about two
hours, so the time is set to 02:00.
Temperature sensor faulty
Measurements from connected sensors (except the outside sensor) are reliable as long as measurements are
between -99.9ºC and +99.9ºC. Outside these limits, the measurements are unreliable. The control computer will
give an alarm. This can mean that the temperature sensor has not been correctly connected or is defective. The
screen displays # at the temperature readout.

Connect the Aura 14 as follows:
1. Open the cover.
2. Connect the Aura 14 to the manual switch.
3. Connect the manual switch to the main supply (be sure power is disconnected).
4. Connect other (signal wires) to the Aura 14, see chapter Technical specifications.
5. Close the cover.
Always use the cable swivels when connecting the Aura 14. Use the sealing discs supplied to seal off
any unused swivels. Use a sealant to seal all swivels, after the computer has been connected, to
prevent the entry of moisture, dust and/or aggressive gasses.
Check that the mains voltage and frequency, for which this computer is suitable, correspond to the
mains voltage and frequency on site.
Be sure that the Aura 14 is properly grounded. When using metal cable trays, grounding at one point of
the tray is recommended.
The Aura 14 should be possible to shut down with a double pole switch.
Connect the Aura 14 to a group from the main distributor and mount in separate cable trays.
Limit the length of the signal wires much as possible; avoid crossing high/low voltage wires.
To protect against lightning, place an over voltage protection device in the power supply of the Aura 14.
Condensation should never occur in the control computer.

Use of the terminal resistor depends on the location of the control computer in FNet. Control computers or end
stations at the beginning of the network require a terminal resistor. Depending on the device type a 120 Ohm
resistance, a jumper or a dipswitch is used to terminate the control computer.
Example: Setting the terminal resistor FNet
Four control computers connected using FNet.
Control computers 1 and 4 are at the end of the network. These control computers must be terminated.
Control computers 2 and 3 are looped. These looped control computers do not require a terminal
resistor.
The Fancom Greenlink cable (UTP 1x2x0.8mm, unshielded twisted pair) used to wire the FNET and I/O
net. Maximum cable length = 1200 meters.
