Minimum average water temperature
If the fan coil runs continuously in cooling
mode in an environment with high
relative humidity, condensate may form
on the air flow outside the appliance.
This condensate could drip onto the
floor and onto any underlying objects.
To prevent condensation phenomena on
the external structure of the appliance
with the fan running, the average water
temperature must not drop below
the limits indicated in the table. These
limits depend on the temperature and
humidity conditions of the room air.
These limits refer to operation with the fan
running at minimum speed.
Condensation may form in the event the
fan is off for a prolonged period and cold
water flows in the coil;
therefore, we
recommend installing the 3-way valve
(accessory).
OPERATING LIMITS
Water temperature
In order to prevent air stratification in
the environment and thus have a better
mixture, the fan coil should not be
supplied with water that is hotter than
65°C.
Using water at a very high temperature
can cause creaking due to the heat
expansion of the elements (plastic and
metal), however, this does not cause
damage to the unit unless the maximum
operating temperature is exceeded.

The earth leakage current of several
devices placed under the same circuit
breaker is summed, therefore we
recommend paying attention to the
calibration value of the circuit breaker and,
if necessary, consider splitting the
installation in more circuits, each of which
protected by its own circuit breaker.
