Action
Er01 Auger or boiler safety
thermostat
It occurs if the hopper (85ºc)
or boiler (95ºc) limit
temperature is exceeded.
The water is not circulating.
Circulator pump blocked with
dirt, installation with air in
the circuit, or closed radiator
valves.
Check the installation.
Wait for the boiler or
hopper to cool down
and for the message
Stop or OFF to appear
on the display.
Er02 Combustion chamber safety
pressure switch.
Occurs if the combustion fan
cannot make a depression in
the combustion chamber
greater than 20Pa.
Chimney clog.
Door or ash drawer not
properly closed.
Loose door cord.
Silicone tube or clogged
pressure socket.
Return of wind through the
chimney
Check chimney
cleanliness
Check the door and
seals.
Check the pressure
gauge of the pressure
switch.
Er03 Smoke temperature sensor
Extinguishing combustion due
to low smoke temperature,
lack of fuel
Occurs if the smoke
temperature drops below the
minimum value set for
extinguishing.
Lack of fuel
Low calorific fuel
Too-down correction of pellet
recipe
Refill hopper
Check fuel quality and
replace.
Er04 Boiler temperature sensor
Exceeded boiler water
temperature (90ºc).
Circulator pump blocked, air
in circuit or any valve closed
or blocked.
Check the installation.
Wait for the boiler or
hopper to cool down
and for the message
stop or off to appear on
the display.
Er05 Smoke temperature sensor
Extinguishing combustion due
to excessive smoke
temperature.
Lack of cleaning of the smoke
circuit.
Lack of dissipation,
obstructed or blocked
ambient fan.
Correction too upwards of the
pellet recipe
Perform boiler
maintenance. The
exchange circuit will be
closed.
Check pellet recipe
normal value 0.
Er07 Combustion fan encoder.
Combustion fan encoder
error:
Occurs if the rotation signal is
not received by the
controller.
Check the plug and
connecting cable on the fan
and controller
Reset the error and
restart the boiler, if the
error persists, call a
technician.
Er08 Combustion fan encoder.
Occurs if the controller is
unable to obtain rotational
speeds according to the value
defined by it.
Check the plug and
connecting cable on the fan
and controller
Possible fan or encoder
malfunction
Reset the error and
restart the boiler, if the
error persists, call a
technician.
Er09 Water pressure sensor
Occurs if the boiler water
pressure drops below 0.4bar
Water pressure dropped
below 0.4bar.
Check the water
pressure, identify
possible leaks in the
