OPERATING CONDITIONS
7.1
Boiler operation with log wood
HEATING OFF
During this phase the boiler is switched off, i.e. the
burner is blocked.
Scorch phase
In the
BURNING PHASE
condition wait to see if
the logs catch fire in the combustion chamber.
During 30 minutes an adequate flue temperature
(
HEATING UP FROM MIN)
) is adjusted so that it
can be switched on into the
HIGH RUNNING
PHASE
condition. If this flue gas temperature is
not set, it switches into the
HEATING OFF
condition and a corresponding fault is declared.
In this condition it is possible to switch manually
into the UNIT OFF condition.
Start up phase
In the
RUN UP PHASE
condition, after lightings
the logs, it tries to stabilise the combustion and
achieve the minimum boiler temperature. The
optional combustion control (lambda control) is
already activated at this time. When reaching 65
°C the boiler temperature (set out in the program)
it is switched to the control phase. If the flue gas
temperature decreases in this phase (below
FLUE
GAS MIN TEMP.
), it switches into the
RESTART
.
Control phase
The
CONTROL PHASE
condition carries out
actual boiler control, which splits into an output
and combustion control (OPTIONAL).If the boiler
temperature increases in this phase above the
maximum boiler temperature (
BOILER MAX
), it
switches into the
READY
condition. If the flue gas
temperature decreases in this phase below the
allowed (
FLUE GAS MIN TEMP.
) it switches into
the
RESTART
condition.
Ready
The maximal boiler temperature (
BOILER MAX
(P02)
) has been reached due to too low heat
capturing. Therefore the boiler has been switched
off. The boiler starts up again if the boiler
temperature falls 3°C below
BOILER MAX)
.
Restart
The
NEW START-UP
condition tries to re-
stabilise the combustion within a time limit
(adjustable via MAXIMUM RE-START).It will
always be activated if the flue gas temperature is
too low. If there is a stable combustion again, it
switches immediately into the
CONTROL PHASE
.
If a sufficient flue temperature is not achieved
after a specified time (below
FLUE GAS MIN
TEMP.
) the boiler switches off by switching in the
HEATING OFF
condition.
Re-heating
The
RE-HEATING
condition is used for safe
operation for re-heating. If the customer re-heats
a larger amount of logs in operation, then this
operation is activated. The boiler then remains in
this condition for the time set. If the boiler
temperature in the meantime increase above the
maximum boiler temperature, the boiler will be
switched off. After the set time is switched at
sufficient flue gas temperature in the state
CONTROL PHASE
. If the flue gas temperature is
too low (below
FLUE GAS MIN TEMP.
) it is
stopped and an error is displayed. This function
may only be activated by long pressing the
On/Off-switch in the STATUS MENU, if the unit is
in
HIGH RUNNING -
or
CONTROL PHASE
.
Chimney sweeper
The
CHIMNEY SWEEPER MODE
provides a test
mode for the chimney sweeper.The boiler is
operated steadily at nominal output and all
consumer values are set to its maximum during
the
chimney
sweeper
carries
out
its
measurements. The boiler runs high normally and
the chimney sweeper function is only activated
instead of the
CONTROL PHASE
. This condition
is left when deactivation occurs or when the boiler
maximum temperature is exceeded or when the
maximum chimney sweeping time is exceeded
(45min).
Lambda calibration (code protected)
By
activating
the
parameter
LAMBDA
CALIBRATION
in the parameter menu the
calibration starts (only in condition
UNIT OFF
activatable). The lambda sensor is calibrated at
the factory.
Flue gas temperature control
The flue gas temperature control begins if the
HEAT UP FROM MIN
is exceeded. The target
temperature modulates between the set values
FLUE GAS NOMINAL LOAD
and
FLUE GAS
PART LOAD (P05).
In the run up phase as well
as when re-heating, it will be controlled to an
increased flue gas temperature (
FLUE GAS
NOMINAL LOAD + 15
). The 15 °C are a setpoint
specification. The actual temperature deviance
may be higher.
Lambda control
The primary and secondary air is controlled via
the lambda sensor. The control is able to detect
