Shown on display
Type of malfunction or
fault
Cause Solution
Safety thermostat or
siphon pressure switch
triggered
The boiler stops due to activation of
the safety thermostat or the siphon
pressure switch. The system pump
stays on for one minute
- Check whether there is little water in the system
- Check the primary circulation pump
- Check for possible obstruction of condensate drain
- Check the electrical wiring and connections of the
siphon pressure switch tubes
- Once the fault is repaired, press the (reset) button to
start the boiler again
Fault in flame detection
circuit
Detection of a non-real flame signal,
normally before ignition phase
Faulty components
- Check the detection electrode and its connections
- Check the electronic circuit board
No water circulating in
primary system
Poor circulation of water in the
primary water circuit is caused by
the ∆T between the delivery sensor
(SM) and return sensor (SR) and
may occur on start-up or during
operation
- Check system pressure and whether the water level in
the system is low
- Check the primary circulation pump
- Check the delivery sensor (SM) and return sensor (SR)
Tank/anti-freeze sensor
fault
The sensor connected to the AUX
terminals is open or has short-
circuited
- Check settings of parameter PAR 02
- Check the sensor and its connections
Modulator disconnected
error
The gas valve is disconnected from
the electrics
- Check the electrical connection to the gas valve
Smoke probe intervention The smoke detector (SF) has
detected a too high temperature
- Check that the smoke duct, the flue pipe and the
chimney have no obstructions
- Once the fault is repaired, press the (reset) button to
start the boiler again
Smoke probe fault
The smoke detector (SF) is open or
has short-circuited
- Check the sensor and its connections
Fan fault
The fan speed is outside the pre-set
range. If the anomaly activation
condition continues for two minutes,
the boiler carries out a forced stop
for thirty minutes. At the end of the
forced stop, the boiler will try to
ignite again
- Check the fan rpm
- Check the electronic circuit board
Boiler delivery probe
temperature above 117°C
Other safety devices were not tripped
earlier to limit the temperature of
the boiler body
- Check that the delivery probe, safety thermostat and
smoke probe are working correctly
External sensor fault
(flashing warning)
The external sensor (SE) has short-
circuited. The boiler continues
normal operation
- Check the sensor and its connections
Mix 1 zone safety
thermostat triggered
The Mix 1 system's delivery probe
is faulty
The mixer valve has failed
The board has failed
- Check the delivery probe
- Check the mixer valve
- Check operation of the board
- Check the electrical connections of all components
Mix 1 Zone valve delivery
probe fault
The Mix system's delivery probe is
open or has short-circuited
- Check the sensor and its board connections
- Check operation of the board
Mix 2 zone safety
thermostat triggered
The Mix 2 system's delivery probe
is faulty
The mixer valve has failed
The board has failed
- Check the delivery probe
- Check the mixer valve
- Check operation of the board
- Check the electrical connections of all components
Mix 2 Zone valve delivery
probe fault
The Mix system's delivery probe is
open or has short-circuited
- Check the sensor and its board connections
- Check operation of the board
S1 solar delivery probe
fault
The solar system's delivery probe is
open or has short-circuited
- Check the sensor and its board connections
- Check operation of the board
