The earth leakage current of several devic-
es 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.

MINIMUM AVERAGE WATER TEMPERATURE (Tw) [°C]
If the fan coil runs continuously in cooling
mode in an environment with high relative
humidity, condensate may form on the air
flow. 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 tem-
perature 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).
In order to prevent air stratification in the
environment and thus, have better mixing,
the fan coil should not be supplied with
water that is hotter than 65 °C. Using water
at a very high temperature can cause creak-
ing due to the heat expansion of the ele-
ments (plastic and metal). However, this does
not cause damage to the unit unless the
maximum operating temperature is exceed-
ed.
