D.
Dirty brazier. Check the cleaning of the brazier; All holes must be free to allow the flow of
combusting air, Perform seasonal maintenance.
E.
Excessive pellet range (average shorter pellets). Check possibly decrease the technical
parameters inherent in the on times of the cochlea (AUGER) , especially to the higher powers.
Warning Er04
The temperature of the boiler water exceeded the value set in the parameter Th25 (90 degr. C)
ACTION
After letting the boiler cool, unlock the boiler by pressing the control panel to turn on and off for
a long time.
CAUSE
A.
There are air bubbles in the system or boiler. To eliminate them use the vent valve present of
the boiler body or those in radiators.
B.
Presence of interception organs, such as zone valves and/or shutters, which prevent heat
disposal. Open any shutters and in the case of planting in zones make sure that there is at
least one open area.
C.
Circulator blocked. Place the circulator in the vent so that you can check if the engine turner
can unlock automatically, otherwise replace the boiler circulator.
D.
Incorrect technical parameters. Check the P26 parameter (hydraulic configuration). It must
be set in the way that reflects the installation of the product in question (See page
E.
Faulty boiler probe. Observe the indication of the temperature of the water in the boiler on
the control display; The indication must be appropriate for the actual temperature of the
water (not 0 degrees Celsius for example). The resistance of the NTC probe that detects
the temperature of the water in the boiler must be about 10 kὨ at the temperature of 25
degrees C and decrease as the temperature detected (to increase as the temperature
drops). To measure the resistance of the probe, it is necessary to disconnect it from the
electronic control unit; if the measured resistance is 0 ohm or is infinite the probe is to be
replaced because it is short-circuited (indication of 110 degrees C) or interrupted (indication
of 0-C). If the probe's resistance is correct but the temperature display is wrong, the
electronic control unit that does not correctly interpret the temperature detected by the
probe must be replaced.
F.
Faulty circulator. If the temperature of the water in the boiler is > 55 degrees Celsius, there is
a 230Volt Voltage (VAC) between the two N and L contacts of the circulator clamp. If this
Voltage is not present, perform the same measurement directly on terminals 7 and 8 of the
control unit to see if there is a problem with the external connection. If the Volta is not even
present on the connector, you must replace the electronic control unit that does not properly
feed the circulator. If the turner is unlocked and the capacitor efficient but the circulator does
not turn yet, you have to replace the circulator because it is defective.
Warning Er05
PROBLEM
The temperature of the fumes exceeded the value set in the technical parameter Th08 (200
degrees)
ACTION
After letting the boiler cool, unlock the boiler by pressing the control panel to turn on and off for a
long time.
