DESCRIPTION OF THE UNIT

AIM OF THE UNIT
The fan coil is a room air treatment terminal unit for both winter and summer operation.
Omnia UL_N version
A fan coil with cabinet, for universal installation and fitted with a multifunction electronic thermostat. It can be installed as an
autonomous unit or within a network: it can, in fact, manage a network of a further 5 fan coils*.
* The fan coils within a network must be pre-arranged models, or equipped with the special accessories.
AVAILABLE SIZES
The Omnia UL_N fan coils are available in 4 sizes.

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.
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

- 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.
The use of water at high temperatures
could cause squeaking due to the different

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
