● Optimised water consumption (A113 = WATER):
The water misting does not start until all the stages are on and the measurement is above the value of parameter A200.
With On/Off or Mixed control
In this case, misting is controlled as an additional control stage.
When the drycooler is at 100% power and the fluid temperature continues
to increase to the value of parameter A200, misting is activated.

During On/Off control, misting is stopped when the fluid measurement
is equal to the corresponding value at 50% of the operating range of
the last fan stage.
During mixed control 1, misting is stopped when the fan output signal
is equal to 6V.
With variable speed control
From version V07 it is possible to activate misting before being
at 100% on the drycooler by modifying the value of parameter
A113.1.

● Electrical optimisation
Water misting is activated when the outdoor temperature reaches
the value of parameter A199 and at least one control stage is
activated.
