Water temperature
In order to prevent air stratification
in the room, and therefore to achieve
improved mixing, it is obligatory not
to supply the fan coil with water at a
Minimum average water temperature
If the fan coil is working in cold
continuous mode inside an environment
where the relative humidity is high,
condensate might form on the air
delivery. 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

The use of water at high temperatures
could cause squeaking due to the
different thermal expansions of the
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 con-
ditions of the air in the room.
The limits mentioned above refer to
operation while the fan is set
to its minimum speed level.
