This alarm will occur after the feeder
temperature exceeds the service parameter:
Service setting s
→
Burner settings
→
Max. feeder temp.
In such cases, the regulator will attempt to
push out the burning fuel from the feeder by
switching it on for a short time. If three
consecutive attempts to switch the feeder on
do not reduce the temperature, the feeder
will be switched on for a a longer time and
report a constant alarm. Before returning to
regular operation, remove the excess fuel
from the combustion chamber. For additional
information, see pt. 15.
The flame return protection
function will not work if there is no
power supply to the regulator.
The regulator cannot be used as
the only flame return protection.
Use
additional automatic
protection.
9.3 Feeder control system failure
The regulator has an additional protection
preventing it from feeding fuel constantly.
This informs the user about failures in the
electrical system controlling the fuel feeder.
In case of alarm,
stop the boiler and
repair the regulator as soon as possible.
It is also possible to continue operation in
emergency
mode. Before continuing
operation, mane sure that the combustion
chamber does not contain excessive unburnt
fuel. If so, remove the excess fuel. Ignition
with excessive fuel may lead to explosion of
combustion gasses! Emergency mode is
activated
after entering the special
password: 4445. Before activating
emergency mode, familiarize yourself with
the user manual. After accepting the
password, the feeder control is taken over by
the emergency system and the boiler
continues to operate.
Note: operating in emergency
mode is allowed only under user
supervision and until the arrival of
the service team to remove the
failure. If user supervision is not
possible, extinguish the boiler.
When operating in emergency
mode, prevent the consequences of
improper feeder work (feeder
working constantly or not at all).
9.4 Boiler temp. sensor failure
This alarm occurs when the boiler
temperature sensor is damaged or when its
measurement range is exceeded. Check the
sensor and replace it if necessary.
See temperature senor check in pt.
13.10.
9.5 Feeder temp. sensor failure
This alarm occurs when the sensor is
damaged or when its measurement range is
exceeded.
See temperature senor check in pt.
13.10.
9.6 Exhaust temperature sensor failure
This alarm occurs when the sensor is
damaged or when its measurement range is
exceeded.
See temperature senor check in pt.
13.10.
9.7 Boiler ignition failed
This alarm occurs after the third failed
attempt to automatically ignite the furnace
The causes of this alarm include: faulty
igniter or fan, damaged fuel feeding system,
improper parameter settings, low fuel
quality, lack of fuel in the container.
Note: Before continuing operation,
make sure that the combustion
chamber
does not contain
excessive unburnt fuel. If so,
remove the excess fuel. Ignition
with excessive fuel may lead to
explosion of combustion gasses!
9.8 Exhaust temperature not met.
Check fuel quality
This alarm is sounded when the exhaust
gases are not heated above the lack of fuel
detection
threshold in the exhaust
temperature increase time. The alarm
prevents filling the combustion chamber with
