Water temperature
In order to avoid air stratification and there-
fore achieve better mixing it is advised not
supply the fan coil unit with water hotter
than 65°C.
Minimum average water temperature
If the fan coil unit operates continuously
in cooling mode in a room with high
relative humidity, condensate might form
on the air discharge and unit casing. This
condensate might be deposited on the
floor and on any objects underneath. To
prevent the formation of condensation
on the exterior of the unit while the fan
is operating, the average water tempera-
ture should not drop below the operating

necessary to split the installation into
several circuits, each having its own
circuit breaker.
The use of very hot water could cause creak-
ing due to the thermal expansion of the
different components (plastics and metals).
This does not cause damage to the unit if
the maximum operating temperature is not
limits shown in the table below, deter-
mined by the room ambient conditions.
These limits refer to unit operation with
fan at minimum speed.
In the case of prolonged periods with the
fan switched off and cold water passing
through the coil the formation of con-
densate on the unit casing is possible.
