boiler from flashback is disabled.
15.6
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, 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!
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).
15.7
Boiler overheating, STB limiter
open
This alarm occurs when the independent
safety thermostat protecting STB the boiler
from being overheated is activated. The
burner is switched off. After the boiler’s
temperature drops, unscrew the round cover
of the temperature limiter and press the
reset button.

normally with previously preset parameter
values, and in case of alarm occurrence it
takes action related to respective alarm
Check the cable, which connects the control
panel with the module and repair or replace,
if necessary.

Unsuccessful boiler firing-up
attempt
This
alarm
is
produced
after
third
unsuccessful attempt of automatic furnace
firing-up. Upon occurrence of this alarm, all
pumps stop to avoid excessive boiler cooling.
To reset the alarm - confirm it or switch off
and on the regulator. The reason of this
alarm may be, among others, faulty heater
or lack of fuel in the bin.
15.10
Unsuccessful attempt of container
loading
It is so called "silent alarm prompt". It occurs

from additional bin (bunker). In case the
attempts to fill the boiler bin have been
unsuccessfully made within one full hour of
second feeder operation, this prompt is
displayed. It does not stop automatic boiler
operation, only warning message appears on
the control panel.

Power failture
In case of power failure, the regulator
returns to the operation mode in which it was
before the failure.
16.2
Anti-freezing protection
In case the boiler temperature has fallen
below 5
C, CH pump is activated to force
boiler water circulation. It delays water
freezing process, but in case of very low
temperature or lack of power it may not be
sufficient to protect the equipment from
freezing.
16.3
Protection of pumps against
clogging
The regulator performs the function of CH,
HUW and mixer pump protection from
clogging caused by scale deposits. For this
