Operating conditions

Betriebsanleitung_pelletfire_Touch_Englisch_V1.2

9.1.5

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(P02).

9.1.6

New start-up

The  NEW  START-UP(6)  condition  tries  to  re-
stabilise  the  combustion  within  a  time  limit
(adjustable  via  MAXIMUM  RE-START(P07)).  It
will  always  be  activated  if  the  flue  temperature  is
too  low.  If  stable  combustion  adjusts  again,  it
switches

immediately

into

the

CONTROL

PHASE(4). Should a sufficient flue temperature
not be achieved after a specified time (under
HEAT-UP MIN(P06)), the boiler is switched off as
it is switched to the UNIT OFF(1) condition.

9.1.7

Re-heating

The  RE-HEATING(7)  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.  Should  the  boiler
temperature  in  the  meantime  increase  above  the
maximum  boiler  temperature,  the  boiler  will  be
switched  off.  After  the  set  time,  it  switches  to  the
CONTROL

PHASE(4)

condition

once

adequate  flue  temperature  is  reached,  and  if  the
flue  temperature  is  too  low  (under  HEAT  UP
MIN(P06)),  it  is  switched  off  and  reported  as  a
fault.  This  function  may  only  be  activated  by  long
pressing the On/Off-switch in the STATUS MENU,
if  the  unit  is  in  HIGH  RUNNING(3)  or  CONTROL
PHASE(4).

9.1.8

Chimney sweeper

The  CHIMNEY  SWEEPING(8)  condition  is
available as a test mode for the chimney sweeper.
The boiler is precisely operated using rated output
and  the  chimney  sweeper  can  carry  out  its  test
measurements.  The  boiler  usually  runs  high  and
the  chimney  sweeper  function  is  only  activated
instead  of  the  CONTROL  PHASE(4).  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).

9.1.9

Lambda calibration (password

activating

the

parameter

LAMBDA

CALIBRATION  (P20)  in  the  parameter  menu  the
calibration  starts  (only  in  condition  UNIT  OFF(1)
activatable).  The  lambda  sensor  is  calibrated  at
the factory.

9.1.10

Flue temperature control

The  flue  temperature  control  begins  if  the  HEAT
UP  FROM  MIN(P06)  is  exceeded.  The  target
temperature  modulates  between  the  set  values
FLUE  NL(P04)  and  FLUE  PL(P05).  In  the  high
running  phase  as  well  as  when  re-heating,  it  will
be  controlled  at  an  increased  flue  temperature
(FLUE  NL  +  15).  The  15°C  are  a  setpoint
specification.  The  actual  temperature  deviance
may be higher.

9.1.11

Lambda control

The primary and secondary air is controlled via
the lambda sensor. This serves to optimise the
combustion and can detect slight fuel fluctuations.
