4.1.1 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: p. 23.
WARNING!
Cassette is predisposed for standard control MY-
COMFORT, for TED2T disconnect the gray wire of the float
from terminal 4 and connect to free terminal 8, remove the
blue bridge between terminals n and 4, then complete the
connections of the TED2T to the terminal board as in the
wiring diagrams:
Ū p. 25 for ACQVARIA 10-20;
Ū p. 26 for ACQVARIA 40-50-60;
CASSETTE
is predisposed for standard control MYCOM-
FORT, for TED4T disconnect the gray wire of the float from
terminal 4 and connect it through a flying terminal to ter-
minal 3 of the TED4T, remove the blue bridge between ter-
minals n and 4, then complete the connections of the TED4T
to the terminal board as in the wiring diagrams:
Ū p. 27 for ACQVARIA 10-20;
Ū p. 28 for ACQVARIA 40-50-60;
WARNING:
The power supply to the pump-float switch de-
vice must never be interrupted.
4.1.2 Galletti control dedicated (EVO - TED - MY
COMFORT)
Galletti controls implement a logic that makes it possible to set
a fixed speed between minumum, medium and maximum, or
automatic speed modulation.
The automatic logic varies the analog signal to the motor be-
tween minimum, medium and maximum speed, based on the
distance from the set-point, in order to accelerate the imple-
mentation phases.

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.
4.1.3.1 Condensate drain connection
Connect a rigid PVC pipe to the end of the hose and secure it
with a clamp
Correctly insulate the pipe with polyethylene foam.
Ū Be careful of the risk of freezing in winter in suspended ceil-
ings.
Ū If necessary, the condensate pipe can be routed immediately
after the unit's outlet. Maximum height: 900 mm (FIGuRE 1).
Ū Make sure that the drainpipe has a slight slope in the direc-
tion of flow and that it does not form a siphon (FIGuRE 1).
Ū The piping must have several supports (FIGuRE 2).
Ū Do not install an air vent (FIGuRE 3) in the wrong position.
