TECHNICAL DATA AND OPERATING LIMITS
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.
The limits mentioned above refer to
operation while the fan is set to its
minimum speed level.
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.
Water temperature
In order to prevent air stratification in
the room, and therefore to achieve
improved mixing, it is advisable not
to supply the fan coil with water at a
temperature over 65°C.
The use of water at high temperatures could
cause squeaking due to the different
thermal expansions of the elements
(plastic and metal), this does not however
cause damage to the unit if the maximum
operating temperature is not exceeded.

Performance values refer to the following conditions:
- at the maximum motor speed;
- the total input power is determined by adding the input power
for the unit and the input power for the accessories connected
and declared in the corresponding manuals.
