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
overheating light (SS).
To restore the initial settings, the switch (AA) must be enabled after the
water temperature in the boiler-stovehas 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 fluid reaches the temperature set through the regulator, the 3-
way valve diverts the fluid to the radiators and the operating light (SV)
goes on.
When the temperature of the fluid drops below the set value, the system
opens the electrical circuit and the 3-way valve bypasses the fluid directly
to the boiler-stove.
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 boiler-stoves.
The sensor of the operation, protection and control devices must be placed
directly on the boiler-stoveor at most on the flow pipe, no more than 5 cm
away from the boiler-stoveand in any case before any intercepting device.
The sensor must be immersed in the well.
Installation
Follow this procedure to install the electronic regulator correctly: 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.
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.
Connect the brown wire (phase) and blue wire (neutral) of the 3-way
Valve, respectively, to terminals 5 and 6 of the regulator.
Connect the yellow/green wire to the earth.
Follow the assembly instructions contained in the
package to connect the regulator to the system properly.

IMPORTANT ADVICE REGARDING THE INSTALLATION
The connections, commissioning and verification of proper operation
of the boiler-stoves must be carried out by qualified personnel, 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
connection 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 boiler-
stoves. It is also obligatory to connect the pump, valve and metal
parts of the boiler-stove to an earthing system.
