Water temperature
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
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. This
condensate could drip onto the floor and onto
any underlying objects. To prevent condensation
phenomena on the external structure of the

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.
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).
