How to solve
PROBLEM 1
– Set values of parameters Uc00 and Uc01 to the factory values or
near-factory values.
Possible
cause 2
PROBLEM 2
– Fan speed in the flame stabilization phase. The boiler enters the ignition phase,
smoke appears, the display indicates Stb which means it's in the flame stabilization phase but after
that, the boiler shuts down. The most common cause of this is a too weak fan in the stabilization
phase which is determined by parameter Uc04.
How to solve
PROBLEM
2
– Increase fan speed using parameter Uc04.
Possible
cause 3
PROBLEM 3
– Too big or too small amount of pellets in the stabilization phase. If there are not
much or too many pellets while the display is indicating Stb, that is stabilization, flame congestion
can occur and the boiler may return to the shutdown phase. The amount of pellets in the
stabilization phase is regulated by parameter CL04.
How to solve
PROBLEM
3
– value of parameter CL04 to the factory value or near-factory.
Possible
cause 4
PROBLEM 4
– The boiler entered the stabilization phase but still enters the shutdown phase
because the temperature increase is not sufficient. Particularly stagnation, that is marginal drops of
the temperature of flue gases is noticeable at the moment of refilling the furnace with pellets.
How to solve
PROBLEM
4
– Increase the temperature of flue gases for system to enter Fire ON
and that is parameter F18. That way, it is harder for new pellets entering the combustion chamber
to reduce the temperature of flue gases because the flame is stronger because it was given more
time until refilling. This problem is the most common in case of weak chimneys or the traction of
a chimney is weak due to some other reason.
Possible
cause 5
PROBLEM 5
– The boiler entered the stabilization phase but after some time enters the
shutdown sequence.
How to solve
PROBLEM 5
– The ash dump was forgotten to be put back into the boiler or
to be closed firmly.
