Integrated in an electrical panel, this board performs the following functions:
• temperature or pressure control,
• operation parameter monitoring,
• communication with CIAT chillers,
• diagnostics and fault storage,
• communication with the remote control console, ancillary boards,
and customer BMS (bus).
Ambient air:
During operation: min./max. temperatures = -25°C/40°C
Stored: min./max. temperatures = -40°C/80°C
Single-phase fluid: min./max. adjustment temperature = 5/90°C (up to 150°C
optional)
Refrigerant: min./max. set pressure: 5/45 bar
Board supply voltage: 230 V
The AeroConnect board is used to control the dry coolers and air-cooled
condensers

Control
choices
On/Off control
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.
Used for cascade control of fan stages:

Spray
(units with spray
ducts)
Used to remotely authorise or prohibit the operation of the machine.
The machine is on when the contact is closed.
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.
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.
The running time of each fan stage is balanced by a time counter.
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.

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 mm
