Control
choices
Three types of control are possible. Refer to your order acknowledgement
to see which type you have selected:
•On/Off: Cascade control by activation of fan stages.
•Speed control: Fan speed control.
•Mixed: Speed control on stage 1, cascade control for the following
stages.
On/Off control Used for cascade control of fan stages:
The diagram below illustrates this type of control:
Speed control
With a speed drive
(option)
Used to adjust the speed of all the fans.

Mixed control
With a speed drive
(option)
Used to adjust the speed on stage 1. Cascade control is used for the other
fan stages.
The diagram below illustrates this type of control:
Automatic
machine operation
control
Used to remotely authorise or prohibit the operation of the machine.
The machine is on when the contact is closed.
Manual
override
Used to turn on all the fans. The machine is in override mode when the
contact is closed.
Manual override can be activated and deactivated either directly on the unit or
remotely.
Two setpoints Used, for example, for summer/winter or day/night operation. Each circuit can
have up to two control setpoints. These setpoints can be switched via the dry
contact (On/Off), the console or over a BMS.
Stage runtime
balancing
The running time of each fan stage is balanced by a time counter.
Spray
(units with spray
ducts)
Used to increase the efficiency of the AeroConnect by spraying very fine
droplets of water into the ambient air to cool it through evaporation.
Two options:
- Optimised water consumption: the water spray does not start until all the
stages are on and the setpoint is exceeded.
- Optimised electricity consumption: the water spray does not come on until
the outdoor temperature reaches a preset value.

Free cooling During free cooling, the dry cooler is run with a CIAT chiller. Both units are
controlled by the board.
The three-way valve can be controlled by the board provided the maximum
current is 3 A and the maximum voltage is 230 V. Refer to the chiller pump
curve to size the valve.
Link with CIAT
chiller
The following information is exchanged between the dry cooler (DC) or the
condenser (CO) and the chiller (CH):
CH > (DC / CO) (DC / CO) > CH
•Chiller on/off •DC or CO on/off
•Setpoint (CO) •Free cooling
•Pressure value (CO) •Fan stage fault
•Sensor fault
BMS link
With the exception of the language, control type (local, remote),
communication mode and bus number, all the parameters can be accessed
in read and write modes.

Single-pair shielded cable required. Capacitance between wire and shield:
120 pF/m – Resistance of 56 Ω/km.
Examples: Filotex FMA 2P or Filotex IBM 7 362 211.
The shield must be connected at each end to the 0 V line (terminal 3 on J13 or
J12) on the units and the earth to the PLC end. The shielding braid must be as
short as possible (2 cm max.).
The cables must be routed at a distance of at least 30 cm from the power
cables. However, if a power cable intersects with a computer cable, they must
do so at a right angle.
For distances of less than 30 metres, use a shielded cable and keep it at least
30 cm away cm from all lines that could generate interference.
For distances of over 30 metres, install a relay for each input near the board.
Signal output of 0/10 V. Minimum VFD input impedance of 1 kΩ. Shielded cable
connections. Shield connected at both ends to earth. Minimum cross-section of
0.32 mm2(1.5 mm2 max.).
Potential-free dry contacts. Maximum current of 10 A (AC1 load), minimum of
5 mA. Voltage of 12 to 230 V AC. Maximum connection cross-section of
2.5 mm2.
