Fuel ignition in auger channel. The controller empties ignited fuel from the auger
channel until temperature drops.
ALARMS Safety and temperatures sensors failure alarms.
STOP.
Controller maintains central heating and domestic water pumps operation only to
protect the boiler against overheating and auger channel ignition. Room thermostat
contacts closing(call for heat) and domestic water temperature drop do not result in
any action. Pressing START button will result in switching the controller to STAND-
-BY mode.
STAND-BY.
In this mode controller does not carry out any additional operation, until room
thermostat contacts close (call for heat) or domestic water temperature drop, the
boiler operation will focus on maintenance of temperature according to thermostat
setting programmed with the knob. If preheating of domestic water tank is necessary
and the desired boiler temperature setting is higher from domestic water
temperature setting the controller will follow higher setting. Pressing the STOP
button () will result in switching to STOP mode.
IGNITION.
Boiler controller is switched into IGNITION mode if demand for heat follows, and if
the controller did not detect the flame. During ignition the controller activates fan,
auger and igniter. Fuel and air feeding rate is adjusted by the technician. IGNITION-

stabilizing the fan runs at a speed the same as when operating in maximum power.
tray gives fuel quantity such as the minimum power. in addition, depending on the
service settings fuel dose may be increased gradually. stabilization of the firing conti-
nues for the time programmed in the settings of the service or until the boiler
temperature. pressing the stop button, exceeding the working time without
cleaning, opening the contacts of the thermostat or to achieve the required water
temperature in the hot water tank during operation stabilization ignition, the controller
will switch to after-burning mode.
CAUTION! Stabilization of ignition can be turned off by a service technician. In this
case, after the fire the controller switches to work with maximum power.
MAX. POWER OPERATION MODE.
When in this mode the controller operates fuel auger and fan to ensure max. power
of the boiler. Fuel and air feeding rate is adjusted by the technician. Pressing STOP
button, exceeding time limit for cleaning, thermostat contacts opening or if water
temperature in domestic water tank is obtained during operation in MAX. POWER
mode will result in switching of the controller into EXTINCTION (SHUT DOWN)
mode.
MODULATED POWER OPERATION MODE.
Depending on desired parameters the controller may gradually reduce fuel and air
rate feeding to reduce burner power, as much as boiler water temperature corre-
sponds to the programmed setting. Pressing STOP button, exceeding time limit
for cleaning, thermostat contacts opening or if water temperature in domestic water
tank is obtained during operation in MODULATED POWER mode will result inswit-
ching of the controller into EXTINCTION (SHUT DOWN) mode.
MINIMUM POWER OPERATION MODE.
When in this mode the controller operates fuel feeding and fan operation to maintain
firing to ensure the minimum fuel consumption. Fuel and air feeding rate is adjusted
by the technician. If in spite of boiler minimum power, increase temperature follows
of water temperature in relation to the top hysteresis parameter setting, the controller
will be switched into EXTINCTION(SHUT DOWN) mode. When the boiler water
temperature drops below the desired setting it will result in switching of the controller
into „max power operation mode”. Pressing STOP button, exceeding time limit for
cleaning, thermostat contacts opening or if water temperature in domestic water tank
is obtained during operation in MINIMUM POWER mode will result in switching of
the controller into EXTINCTION (SHUT DOWN) mode.

SCAVENGE (AIR PURGING).
During the operation with minimum power output, the controller will activate flue sca-
venge (purging) to ensure removal of accumulated gases. Scavenge (purging) is
provided with temporary fan operation in higher speed.
EXTINCTION (SHUT DOWN).
When in this mode the controller turns off the fuel auger and engages the fan to en-
sure complete fuel combustion and the burner cool down. Fan power when in
EXTINCTION (SHUT DOWN) mode is determined by the technician. When
EXTINCTION (SHUT DOWN) is finished the controller is switched into CLEANING,
STAND-BY or STOP mode, provided EXTINCTION (SHUT DOWN) followed as a re-
sult of STOP button pressing.
BLANKING MODE.
In this mode, the controller changes the fan speed on the value programmed by
a service technician to burn off excess fuel and cool the burner. After putting out the
fire controller switches to CLEANING, ARMED or STOP depending on what caused
the start of the sequence Afterburning EXTINCTION.
CLEANING.
Automatic burner cleaning occurs after time set limit by programmer. In this mode
controller starts cleaning system for preset time. After this procedure controller
resets back to STANDBY mode.

press START and hold button for 5 seconds to start refilling. Refilling follows accor-
ding to the time programmed by the technician or until it is manually turned off with
STOP button.
AUGER EXTINCTION (EMERGENCY SHUT DOWN).
If the auger is equipped with a temperature sensor, a temperature increase above
the range programmed by the technician, it will result in activation of auger ignition
alarm. The controller turns off the fan and auger. If the burner is equipped with the
stoker, the device is switched additionally into AUGER EXTINCTION(EMERGENCY
SHUT DOWN) mode. During shut down the stoker is engaged for the time needed to
remove the ignited fuel from the stoker. In addition if the burner has cleaning mecha-
nism, the controller will activate the cleaning cycle and remove fuel from the burner.

ALARMS.
RK-2006SPGM controller continually checks operations of installed devices as well
as alarm sensors. In case of failure, the device activates alarm and proper opera-
tions are carried out. Information on the problem is also shown on the display.
In addition depending on nature of damage the inner sound alarm system may be
activated. To cancel alarm, first identify the cause and repair it and then STOP but-
ton shall be pressed. If alarm is cancelled and required repairs did not follow, sound
alarm system will be turned off only. In case more than one alarm has been activa-
ted, information on each alarm will be displayed alternately.
Out of fuel alarm.
If in IGNITION mode the controller fails to detect a flame within the time specified by
the technician, „Out of fuel alarm” will be activated. To turn on the controller again
first refill fuel, cancel the alarm with STOP button and begin setting-up process by
pressing START button.
Emergency alarm.
Depending on construction type, the boiler may be equipped with emergency sensor
(e.g. hopper cover sensor). Activation of the alarm will result in fan and auger turning
off, and switching the controller into STAND-BY mode.

2.x Overall.
2.1 Language selection – RK-2006SPGM controller interface offer the function of
language selection. Number of available languages depend on software version
being used.
2.2–2.4 Brightness, saturation, contrast of the display – the parameters enable
the user to adjust the display to his/her own needs.
2.5 Service settings – setting and confirm with the OK button to display the value
YES when this option will delete all the parameters and assign them to the pre-pro-
grammed by the installer or service technician.
2.7 Testing out – in order to verify the correctness of the controller, it is possible to
test various output devices. This feature is available in service mode only if the adju-
stment process is stopped, ie. The regulator before entering the service mode was in
STOP mode. Selecting output testing allows the control knob to select the outputs
on the display. Pressing OK allows you to temporarily attach the selected output. In
order to complete the testing procedures exit, press the STOP button.
3.x Fan operation parameters.
3.1 Fan modulation during boiler start – selection of „YES” setting means that fan
speed modulation will be provided during boiler start.
3.2 Min. fan speed during heating up – this parameter is available, if the function
of fan modulation during boiler start is selected. This parameter specifies power of
the fan during boiler start.

3.3 Max. fan speed during heating up – this parameter is available, if the function
of fan modulation during boiler start is selected. This parameter specifies power of
the fan at end of boiler start.
3.4 Ignition modulation start delay – this parameter is available, if the function of
fan modulation during boiler start is selected and it describes operation time of the
fan with speed according to the selected „Min. fan speed during boiler start” setting.
After time expire the controller will increase fan speed up to the selected „Max. fan
speed during boiler start” setting.
3.5 Fan speed during ignition – this parameter describes power of the fan speed
during ignition. This parameter is unavailable if „Fan speed modulation during igni-
tion” was selected.
3.6 Fan speed at max. power – means the fan power when burner of the boiler
works with maximum power.
3.7 Fan speed at min. power – means the fan power when burner of the boiler
works with minimum power.
3.8 Fan speed during extinction (shut down) – means fan power during burner
extinction (shut down).
