The leakage current to earth of several
devices placed under the same circuit
breaker is summed, so attention should
be paid to the calibration of the circuit
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
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 the floor and on any
objects underneath.
To avoid condensate on the external

the coil, condensate may form on the
external case of the unit. As a result,
we recommend including the 3-way
