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

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
