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 underneath
and on the floor.

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
conditions of the air in the room.

In the event of prolonged fan inactivity
and with cold water passing through
the coil, condensate may form on the
external case of the unit. As a result,
we recommend including the 3-way
valve accessory.
