Minimum average water temperature
If the fan coil is working in continuous
cooling mode in an environment where
the relative humidity is high, condensate
might form on the air delivery and on the
outside of the device. This condensate
might be deposited on any objects

To avoid condensate on the external
structure of the device while the fan is
functioning, the average temperature of
the water must not be lower than the
limits shown in the table below, that
depend on the thermo-hygrometric
