If the valves are not installed, there could be abundant con-
densation, especially if the unit is not operated for long pe-
riods of time.
During wintertime periods of quiescence, drain water from the
system, to prevent ice from forming. If anti-freeze solutions are
used, check for their freezing point using the table below.

Electrical connections

Make the electrical connections whilst the power supply is
disconnected, in accordance with current safety regulations,
carefully following the wiring diagram and its legend.
Check that the mains electricity supply is compatible with the
voltage shown on the unit rating plate.
The electrical connections indicated must be made by the
installer.
For each fan coil a switch (IL) should be mounted on the power
supply, with opening contacts at a distance of at least 3 mm and
a suitable protection fuse (F).
For the electrical connections of the controls, follow the dia-
grams in the figures from:.
WARNING: The power supply to the pump-float switch de-
vice must never be interrupted.
Galletti control dedicated (TED - EVO - MyComfort)
Galletti controls implement a logic that makes it possible to set
a fixed speed (shown in the figure with analog signal 3, 6, 8 V)
or automatic speed modulation, that takes full advantage of the
BLDC motor.
The automatic logic varies the analog signal to the motor be-
tween 2 and 10 V, based on the distance from the set-point, in
order to accelerate the implementation phases and then settle
at a very low holding speed.

To optimise performance, it is advisable to make the following
connections on the exchanger:
Ū Unit outlet: connection below.
Ū Unit return: connection above.
WARNING: While making the connections, hold the water
connections of the unit tightly in place with a hexagonal
wrench or make sure that they do not rotate, in order to pre-
vent the pipes inside the unit from being damaged.
Ū Carefully insulate the inlet and outlet water pipes as well as
the devices installed in the network (on/off valves...). Use a
material that is suitable for the operating conditions and wa-
ter temperature.
Ū Bleed air from the exchanger by means of the air vent valves
located next to the water connections of the coil. Depending
on the installation, it may be necessary to place other vent
valves on the hydraulic system.
