12. BURNER WORKING STAGES
OFF -
burner doesn't work (OFF - burner will not start)
A0 -
burner start - only burner fan is working
A1 -
start of start up safety time measuring, start of igniter working
A2 -
start of transporter working (initial filling)
A3 -
end of initial filling (transporter stops), waiting for the flame (in case flame doesn't appear in set time
error E2 will appear, ignition fail)
A4 -
start of time measuring until entering into the transition stages and additional working time measuring of
electric igniter; a flame loss monitoring is started and if there is no flame for more than 4 minutes, the
controller gets the burner working mode back to stage A3 (electric igniter is working)
A5 -
end of additional igniter working, start of time measuring to enter transition stage PP1
PP1 -
transition stage 1
PP2 -
transition stage 2
PP3* -
transition stage 3*
PP4* -
transition stage 4*
PP5* -
transition stage 5*
A6 -
the burner working mode before reaching the nominal power (fan spins at higher rate than the set value);
if there is a flame loss for longer than 15 seconds, the controller gets the burner working mode back to stage
A3 (electric igniter is working)
P -
(factory selected) burner nominal power
PX*** -
burner nominal power (P6, P5, P4, P3, P2 - depends of the burner set power)
M4** -
modulation stage 4
M3** -
modulation stage 3
M2** -
modulation stage 2
M1** -
modulation stage 1
PFON230 -
power failure and power return stage - (burner tries to establish normal work after power supply failure
and return of the power supply)
F1 -
(factory selected for CPPL 60/70/90 kW) overload phase of the pellet inlet pipe overload sensor
S7 -
(factory selected) the first step in the burner extinguishing phase
-
the screw feeder doesn't work, the fan works as in previous phase (if it spins within factory / authorized
serviceman min / max value), duration: (factory setting) 7 minutes
S7-1 -
(factory OFF, this option can be chosen instead option S7 by an authorized serviceman) - the first
step in the burner extinguishing phase
- the screw feeder doesn't work, the fan works as in previous phase (if it spins within factory / authorized
serviceman min / max value), duration time is until flame loss is spotted or up to (factory setting) 5 minutes
S7-2 -
the second step in the burner extinguishing phase
- the fan spins at maximum rate, duration: (factory setting) 2 minutes
S7-3 -
STANDBY (phase) – the burner waits for some of the start conditions (temperature difference in the boiler,
hydraulic crossover temperature, buffer tank temperature, demand in deating circuit(s), DHW tank heating
demand...)
* - transition phase number depends on selected / installed burner heating power
** - (factory selected) modulation number depends on selected / installed burner power and (on) selected
modulation
level
*** - (disabled by defaul, an option that can be selected instead of modulation option by an authorized serviceman)
the nominal (the maximum rated) heating power depends on selected / installed burner heating power
