IMPORTANT ADVICE REGARDING THE INSTALLATION
The connections, commissioning and veri cation of proper
operation of the replace must be carried out by quali ed per-
sonnel, who can implement all connections in accordance with
the laws in force, particularly with Italian Law No. 46/90, apart
from complying with these instructions.
Compliance with regulations regarding the earth connec-
tion is fundamental for the safety of people.
It is obligatory to install a differential circuit breaker switch
before the device and the entire electrical circuit of the thermo
replace.
It is also obligatory to connect the pump, valve and metal parts
of the thermo replace to an earthing system.

OPERATION
- Control device:
• Thermometer
- Protection device (acoustic alarm system):
• Acoustic alarm (AA)
• Overheating alarm (SS)
This system intervenes when the water temperature exceeds
90° C and warns the user to stop adding fuel.
The acoustic alarm can be disabled from the switch (AA).
However, the alarm remains enabled by means of the overhe-
ating light (SS). To restore the initial settings, the switch (AA)
must be enabled after the water temperature in the thermo
replace has cooled down.
Power supply device (circulation system):
• MAN-OFF-AUTO selector (S)
• Pump light (SP)
The pump remains on when in manual mode and off when in
OFF mode. When in AUTO mode, the pump is activated by the
system when the desired temperature is reached, by means of
the internal setting (RIC), which ranges from 20 to 80° C (this
is pre-set at 20° C).
- Operation device (setting system):
• 3-way valve opening setting (R)
• 3-way valve operating light (SV)
When the uid reaches the temperature set through the regu-
lator, the 3-way valve diverts the uid to the radiators and the
operating light (SV) goes on.
When the temperature of the uid drops below the set value,
the system opens the electrical circuit and the 3-way valve
bypasses the uid directly to the thermo replace.
Attention: During normal operation check that the warning
lights (SV) and (SP) are lit.
POSITIONING
The electronic regulator must be installed close to the thermo
replace. The sensor of the operation, protection and control
devices must be placed directly on the thermo replace or at
most on the ow pipe, no more than 5 cm away from the ther-
mo replace and in any case before any intercepting device.
The sensor must be immersed in the well.
INSTALLATION
The power supply must be disconnected from the mains
and the AUTO-OFF-MAN selector (S) must be in the OFF
position when all these operations are carried out.
Follow this procedure to install the electronic regulator cor-
rectly: loosen the fastening screw, remove the cover and fasten
it in place against the wall with the dowels supplied.
Then make the connections, paying utmost attention to the
wiring diagram and pass the wires through ducts that are in
conformity with the regulations in force. Put the cover back in
place and tighten the screw.
Connect the brown wire (phase) and blue wire (neutral) of the
3-way Valve, respectively, to terminals 5 and 6 of the regula-
tor. Connect the yellow/green wire to the earth.
Follow the assembly instructions contained in the package to
connect the regulator to the system properly.
