Electrical Connections; Rotating The Coil - AERMEC FCX ACT Bedienungs- Und Installationsanleitung

ELECTRICAL CONNECTIONS

WARNING: check that the power supply is disconnected
before performing operations on the unit.
WARNING: the electrical connections, the installation of the
fan coils and relevant accessories should be performed by a
technician who has the necessary technical and professional
expertise to install, modify, extend and maintain systems, and
who is able to check the systems for the purposes of safety
and correct operation.
CONNECTION CABLES SPECIFICATIONS
Use H05V-K or N07V-K type cables with 300/500 V insulation,
piped or ducted.
All the cables must be piped or ducted until they are inside
the fan coil.
The cables coming out of the pipe or duct must not be subject
to stretch or twisting. They must be protected from weather
AUTOTEST
IT IS necessary to activate the Autotest function to
verify the operation of the fan, the valves and the
resistance.
The Autotest sequence is as follows:
1) Selector (B) in central position.
2) Selector (A) set to OFF.
3) Use the selector (A) to carry out the following
sequence quickly:
AUTO → OFF → V1 → OFF → V2 → OFF → V3
→ OFF.
Now, you enter in AUTOTEST mode, the FUCHSIA
LED flashes.
4) With the selector (A) set to AUTO, the valve
turns on.

ROTATING THE COIL

If hydraulic connections require the rotation of the coil, remove
the mobile section and proceed as follows:
– disconnect the electrical wirings from the control board,
remove the circuit card from the panel on the right;
– undo the screws and remove the coil case;
– remove the screws securing the coil, then remove the coil;
– remove the push-outs on the right-hand side;
– rotate the coil and secure it it with the screws previously
removed;
– refit the cover, secure it with the screws, then insert the
plastic plugs supplied in the holes left free by the hydraulic
connections; all the trays can be used to collect condensate
on both sides. In case of vertical installation, to discharge
condensate on the right side, position the drain connection
to the right.
– slide out the electrical connection from the right-hand sided,
remove the push-out and move the cable guide from the right

conditions.
Stranded wires can only be used with terminating sleeves.
Make sure that the strands of the wires are inserted properly.
When making the connections, follow the wiring diagrams
supplied with the equipment and shown in this document.
W i r i n g
Please refer to the ones supplied with the unit.
To protect the unit against short circuits, fit an omnipolar
magneto-thermal trip 2A 250V (IG) to the power line with a
minimum contact opening distance of 3 mm.
Each control panel can control a single fan coil.
The control panels only comprise electric circuits connected
to a power supply of 230V;
WARNING:the probes are fitted with double insulation as
they are exposed to a power supply of 230Vac.
– transfer the electrical wirings to the left side through the
– move the control board and the ground jumper connection
– refit the control card on the left side and reconnect the
– in the FCX-ACT versions, modify the air filter to the new

The yellow LED (D) performs cycles of 1 blink.
5) With the selector (A) set to V1, the minimum
speed V1 comes on. The yellow LED (D)
performs cycles of 2 blinks.
6) With the selector (A) set to V2, the medium
speed V2 comes on. The yellow LED (D)
performs cycles of 3 blinks.
7) With the selector (A) set to V3, the maximum
speed V3 comes on. The yellow LED (D)
performs cycles of 4 blinks.

configuration by changing the position of the external support
in relation to the filter (Fig. 1): press down on the tab (1 Fig. 2)
with a screwdriver while moving the external support (2) until
the tab is over the tooth (3).
Then release the tab so that the position between the support
and the filter is as shown in figure 1.
Given that the contact block on the unit is off-centre in
relation to the cabinet housing, the feet must also be
exchanged.
