INSTALLATION
WARNING: check that the power supply is disconnected before
performing operations on the unit.
WARNING: electrical wiring, 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 the specific case of electrical connections, the following must be
checked:
- 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.
HAZARD: Be particularly careful when fitting the environment
probe. As it might be subjected to network voltage of 230V it must
be firmly fixed.
WARNING: To protect the unit against short circuits, fit an omnipolar
thermal trip max. 2A 250V (IG) to the power line with a minimum
contact opening distance of 3 mm.
WARNING: CHECK THAT THE INSTALLATION HAS BEEN CARRIED
OUT PROPER. it is necessary to perform the Autotest function to
check the ventilator, valve and resistance.
FIXING ON THE MACHINE
To fix the command panel on the fan coil (only on models designed
for the purposes), do the following:
– Cut off the voltage to the unit;
– Remove the fan coil housing
– set the switches on the control panel;
– apply the panel support to the side panel opposite the water
connections and fix it with the screw provided;
– Make the electrical wiring between the control panel and the fan
coil terminal strip then lock the control panel onto the support;
– if the fan coil has a valve (accessory), apply the SW temperature
probe upstream from the valve, otherwise put it into the coil and
lock it with the probe stop;
– refit the housing being careful of the buttons and indication 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 unusual conditions (disconnected wires);
– lock into place with the fixing screw.
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.
Caution: the probe is fitted with double insulation because it is
subject to a voltage of 230Vac.

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
The yellow led (D) performs cycles of 1 blink.
- W i t h
t h e
the V1 position minimum speed
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.
