Performance values refer to the following con-
ditions:
- at the maximum motor speed;
Cooling:
- room air temperature 27 °C B.S., 19 °C B.U.;
• maximum speed:
- water inlet temperature 7 °C; Δt water 5 °C.
Water temperature
In order to prevent air stratification in the
room, and therefore to achieve improved
mixing, we recommend that the fan coil
Minimum average water temperature
If the fan coil is working in cold continuous
mode inside an environment where the
relative humidity is high, condensate might
form on the air delivery. This condensate
might be deposited on the floor and on any
objects underneath the unit.
To avoid condensate forming on the exter-
nal structure of the apparatus while the

cause damage to the unit if the maximum
operating temperature is not exceeded.
for a prolonged period of time, with cold
water passing through the coil, conden-
sate may form on the external case of the
unit. As a result, we recommend including
the three way valve accessory.
