minimum water temperature probe, with the exception of
the PXL2E (that can be used with probe accessory SW3),
PXB and PXBI.
The minimum water temperature probe automatically shuts
down ventilation when the inlet water temperature to the
coil drops below 39°C.
If a three-way valve has been installed, move the minimum
water temperature probe from its seat in the coil to the deli-
very pipe upline of the valve.
Any movement of the water probe requires its replacement
with the SW3 probe (accessory), fitted with a cable of
appropriate length.
CAUTION: given that it is powered to 230 VAC, the probe
has double insulation.
When installing remote control panels with FCS-U version
fancoils, observe the relative wiring diagram; configure the
microswitch (MS) in the panel (controlling the opening of
the delivery grille) in series on the panel power supply.
In the PXL2I, PXL2E and PXL4 electronic thermostat, an
external contact allowing remote control of the fancoil can
be connected to the internal terminal board (EX).
Multifunction electronic thermostats are supplied ready to
operate in standard configuration, though can be adjusted
to the specific operating requirements by means of the inter-
nal dip-switches.
Customised functions vary between models; for this reason,
consult the relative manuals.
Hanging versions with extra-strength motor (PO): select the
appropriate connections on the motor terminal board to
enable three of the seven speeds available. The connections
are made by the manufacturer as shown in the picture
CAUTION: check if installation is correct. For PTI, PXL2I,
PXL2E, PXL4 and PXLM Autotest is necessary to check if
fan, VCF valve and electricl heater work properl.

ROTATING THE COIL

If connection of utilities to the unit requires rotation of the
coil, remove the cover or the front pannel, then proceed as
follows (Fig. 9):
– remove the screw (1) securing the control panel (2) (if
present) to the right side of the unit, then remove it after
electrical disconnection;
– remove the condensate tray (3) (not present on FCS - AS
version);
– remove the coil cover sheet (4) by removing the screws;
– remove the screws securing the coil (5), then remove it;
– remove the push-outs (6) on the right side;
– rotate the coil (5), then secure it in the new position with
the screws previously removed;
– remount the coil cover sheet (4) and secure it with
screws, then insert the plastic plugs (7) supplied in the
openings left free by the hydraulic connections;
all trays are designed to collect condensate on both sides.
In the case of vertical installation, for condensate drainage
on the right side, position the drainage union to the right
(8).
– to move condensate drainage to the right of the unit,
reverse discharge of the tray (3) (if present), then transfer
the drainage line (8) to the right;
– slide out the electrical connections from the right side,
remove the push-out, then transfer the cable guide (9)
from the right to the left side;
– transfer the electrical connections to the left side through
the cable guide (9);
– move the terminal block (10) and the ground jumper con-
12.
nection (11) to the left side of the unit;
– modify the air filter to the new configuration by changing
the position of the external support in relation to the filter
frame (Fig. 3); press down on the tab (12 Fig. 4) with a
screwdriver while moving the external support (13) until
the tab is over the tooth (14). Release the tab when the
position between the support and the filter is as shown in
Fig. 3.
Given that the contact block on the unit is off-centre in
relation to the cabinet housing, the bases must also be
exchanged.
