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.
