3.2 WIRING DIAGRAM.
Remote controls: the boiler is designed to use
the Comando Amico Remoto remote control
V2
(CAR
V2
) or as an alternative to the Super
Comando Amico Remoto remote control (Super
CAR), which must be connected to clamps 42
and 43 of connector X15 on the P.C.B., respecting
polarity and eliminating jumper X40.
Room thermostat: the boiler is designed to use
the Room Thermostat (S20). Connect it to clamps
40 – 41 eliminating jumper X40.
The connector X5 is used for the connection to
the relay P.C.B.
The connector X6 is for connection to a personal
computer.
The connector X8 is used for software updating
operations.
The S34 selector defines the functioning of the
boiler with the system supervisor or with the
external probe:
S34 Off =operation with system supervisor
S34 On =operation with external probe.
3.3 TROUBLESHOOTING.
N.B.:
maintenance must be carried out by a
qualified technician (e.g. Authorised Technical
After-Sales Assistance Service).
- Smell of gas. Caused by leakage from gas circuit
pipelines. Check sealing efficiency of gas intake
circuit.
- Repeated ignition blocks. No gas, check the
presence of pressure in the network and that
the gas adduction valve is open. Incorrect
adjustment of the gas valve, check the correct
calibration of the gas valve.
- Irregular combustion or noisiness. This may be
caused by: a dirty burner, incorrect combustion
parameters, intake-exhaust terminal not
correctly installed. Clean the above components
and ensure correct installation of the terminal,
check correct setting of the gas valve (Off-Set
setting) and correct percentage of CO
2
in flue
gases.
- Frequent activation of the temperature
overload thermostat. It can depend on the lack
of water in the boiler, little water circulation
in the system or blocked pump. Check on the
manometer that the system pressure is within
established limits. Check that the radiator
valves are not closed and also the functionality
of the pump.
- Siphon blocked. This may be caused by dirt or
combustion products deposited inside. Check,
by means of the condensate drain cap, that
there are no residues of material blocking the
flow of condensate.
- Heat exchanger blocked. This may be caused by
the trap being blocked. Check, by means of the
condensate drain cap, that there are no residues
of material blocking the flow of condensate.
- Noise due to air in the system. Check opening
of the special air vent valve cap (Part. 27 Fig.
1-28). Make sure the system pressure and
expansion vessel pre-charge values are within
the set limits; The factory-set pressure values of
the expansion vessel must be 1.0 bar, the value
of system pressure must be between 1 and 1.2
bar.
- Noise due to air inside the condensation
module. Use the manual air vent valve (Part.
13 Fig. 1-28) to eliminate any air present in the
condensation module. When the operation has
been performed, close the manual vent valve.
- Low circulation. The boiler leaves the factory
calibrated with the pump set on Auto and ∆T
between constant flow and return on 15°C.
Check if this ∆T is correct for the system and
if needed modify the pump settings.
