Wall Mounting - AERMEC PXA E Manual De Uso E Instalación

INSTALLATION
WARNING: before carrying out any work, make sure the electrical
power is unplugged.
WARNING: electrical wirings, 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.
In particular, the following checks are required for electrical wirings:
- Measurement of the electrical system insulation strength.
- Continuity test of the protection wires.
Instructions essential for the proper installation of the equipment are
shown here.
The completion of all the operations in accordance with the specific
requirements is however left to the experience of the installation
engineer.
The electronic PXA E control panel must be wall mounted.

WALL MOUNTING

You are advised to position the control panel approximately
1.5 metres of the ground in an area that is representative of the
temperature of the room. Therefore avoid installing in areas where
air stagnates, near doors, windows, heat sources etc.
The control panel may not be fitted on a metal wall unless this is
connected to a grounded outlet permanently.
The assembly site must be chosen in such a way that the maximum
and minimum room temperature limits are complied with 0 to 45°C
(<85% R.H.): furthermore, it must correspond to the command
panel's IP20 degree of protection.
To fix the control panel to the wall, proceed as follows:
– loosen the fixing screw and extract the cover;
– fix the panel to the wall using the holes for the purpose;
– push the cable in from the side and carry out the wiring as per the
wiring diagrams;
– set the switches as indicated in the manual;
– refit the cover being careful of the indicator leds;
– the connection cables must be laid inside the device in such a
way that the cover fixing screw cannot come into contact with the
mains voltage even under anomalous conditions (disconnected
wires);
– lock into place with the fixing screw.
Warning: check that the installation has been done properly. IT IS
necessary to run the Autotest function to check the functioning of
the fan, valves and heating element.

CONNECTION WITH THE FAN COIL
– Cut off the voltage to the fan coil;
– remove the fan coil housing (if there is any);
– make the electrical connections to the control board as indicated in
the fan coil diagrams;
– reposition the housing; for versions that have them, reconnect
the MS power supply microswitch, then fix the screws that were
previously removed;
– complete the installation of the fan coil.
If the fan coil has a water cut-off valve, the SW probe must be
positioned up line from the said valve. If it does not, insert it in the coil
and lock it into place with the probe stop.
Warning: the probe is fitted with double insulation because it is
subject to a voltage of 230Vac.
To protect the unit against short circuits place a 2A 250V (IG)
thermomagnetic switch on the power line.
AUTOTEST FOR INSTALLATION
It is possible to activate an Autotest mode that makes it possible to
check the turning on of all the loads.
The Autotest sequence is as follows:
- Selector switch (A) in the OFF position.
- Position the temperature selector (B) centrally.
- With the selector (A) go through the following sequences quickly:
AUTO - OFF - V1 - OFF - V2 - OFF - V3 - OFF.
At this point you enter the AUTOTEST mode (the left-hand led blinks
fuchsia).
- With selector (A) in the AUTO position the valves or, if there is one,
®
the PLASMACLUSTER come on.
The yellow led (D) performs cycles of 1 blink.
- With the selector (A) in the V1 position minimum speed V1 comes on.
The yellow led (D) performs cycles of 2 blinks.
- With the selector (A) in position V2 medium fan speed V2 comes on.
The yellow LED (D) performs cycles of 3 blinks.
- With selector (A) in position V3 top fan speed V3 comes on.
The yellow LED (D) performs cycles of 4 blinks.
The control panel leaves the Autotest mode automatically after a
minute.
During the Autotest if temperature selector (A) is at minimum, the
yellow led (D) remains permanently on while, if it is at maximum, the
yellow led (D) remains off, in both cases the loads are not tested.
