15.5 Feeder temp. sensor damaged
This alarm occurs in case of damage of fuel
feeder temperature sensor and excess of its
measurement range. To reset the alarm -
switch OFF and ON the regulator. Check the
sensor and replace, if necessary.
Checking temperature sensors
described in this manual, in
point.12.9.
15.6 Exhaust sensor temp. damaged
This alarm occurs in case of damage of
exhaust temperature sensor and excess of its
measurement range. To reset the alarm -
switch OFF and ON the regulator. Check the
sensor and replace, if necessary.
Checking temperature sensors
described in this manual, in
point.12.9.
15.7 Unsuccessful firing up attempt
This alarm occurs after the third unsuccessful
automatic furnace firing up attempt. The
reason behind this alarm occurrence can be
among other things: malfunctioning igniter or
ventilator, malfunction of fuel feeder system,
incorrect parameter setting, insufficient fuel
quality or lack of fuel in the container.
The alarm can be reset by pressing the
encoder “TOUCH and PLAY” knob or restarting
the power supply.
Attention! Before work
continuation it is required to
check, if in the combustion
chamber there was a large
accumulation of unburned fuel. If
it is the case, than it is required to
remove this excessive fuel. Firing
the boiler with an fuel overdose
can lead to an explosion of
combustible gases!.
15.8 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 unburnt fuel. Check
the quality and moisture of the fuel.
The alarm can be reset by pressing the
encoder “TOUCH and PLAY” knob or restarting
the power supply.
15.9 Boiler overheating STB, open
contact
This alarm occurs after activation of
independent safety thermostat that secures
the boiler against overheating. The burner will
then be deactivated. After the boiler
temperature will drop down it is required to
unscrew an oval STB lid and then press the
Reset button.
15.10 Max exhaust temperature
exceeded. Sensor damage danger!
This alarm occurs only when using the GRATE
and exceeding the maximum exhaust
temperature. The fan is turned off. Its aim is
to protect the exhaust temperature sensor
from being damaged by temperatures
exceeding its resistance level. When the
temperature on the boiler drops, the regulator
returns to normal operation.
The alarm can be reset by pressing the
encoder “TOUCH and PLAY” knob or restarting
the power supply.
15.11 No communication
The control panel is being linked with the rest
of the electronics with RS485 digital
communication link. In case a cable of this link
will be damaged, an alarm will occur on the
screen with the information “CAUTION!!! No
communication”.
The controller doesn’t stop to operate and
works
normally with before preset
parameters. It is required to check the
connection cable between control panel and
the module and replaced it with a new one or
repair it.
15.12 Unsuccessful attempt of buffer
loading
This feature has an application only after
module B connection. It is a silent alarm,
which informs about unsuccessful attempt of
adding fuel from additional fuel container
(bunker) to boiler container. In case, when
during preset time of container loading, a
sensor in this container will not detect the
increase of fuel level, this alarm will occur.
This signalisation does not shut down boiler
automatic operation.
15.13 No power supply
This alarm occurs after power to the regulator,
in the case of early no power supply. The
