(EMERGENCY

SHUT DOWN)

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

mode follows till flame is detected. If the flame is not detected within the specified
time, the controller activates „Out of fuel alarm”. Pressing STOP button, exceeding
time limit for cleaning, thermostat contacts opening or if water temperature in
domestic water tank is obtained during operation in IGNITION mode will result in
switching of the controller into EXTINCTION (SHUT DOWN) mode.

Stabilization of the firing.

Boiler burner is switched to the stabilization of the detected flame ignition. While
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
continues 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
corresponds 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 in
switching 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
scavenge (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
ensure 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 result 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

with two methods: burner temperature measurement or brightness measurement. In
case when temperature sensor is used, depending on its location, temperature
measurement range may be from several degrees to several hundred degrees. If
measured temperatures do not exceed 100°C it is recommended to use CT-1 or
CT-2 sensor. In case of higher temperatures, PT-1000 sensor shall be used. For
flame brightness measurement, FD-1 optical detector shall be used.

5.2 Indication correction of flame optical detector – only when flame optical
detector (FD-1) is on. Describes light intensity detected by optical detector when
burner is off. The correction value is deducted from the value light intensity during
the flame detection. Correction allows calibration of FD-1 sensor the way that during
burner shut down value (no flame) of the light equals zero.

5.3–5.4 Hysteresis loss of flame – depending on the type of flame detector, this
parameter specifies how many degrees or units in relation to the threshold set by the
user must cut off the lighter or the brightness of the flame temperature to the
controller began to flame failure detection procedure.

26

WARNING! If the hysteresis is larger than the threshold of igniter shut down, flame

failure detection procedure is started when the temperature drops or the brightness
of the flame to the value of „0”.

5.5 Flame failure detection delay – this parameter specifies how long after the

launch procedures for the detection of flame failure or brightness temperature must
remain below the hysteresis for the regulator to decide that the furnace was
extinguished.

5.6 Fuel ignition time – after igniter and fan are switched on, the controller tests

temperature increase or brightness in the selected location of the burner. If flame is
not detected within the time programmed in this parameter, the controller will repeat
ignition cycle.

5.7 Ignition try count – this parameter specifies how many times ignition may fail

until the controller activates „Out of fuel alarm” and switches into STOP mode. The
alarm is indicated with adequate message displayed on the display. To start the
controller first refill the fuel, then cancel by pressing STOP button and start setting

27

5.12 Smooth stabilization of ignition – setting the parameter to YES will cause the
stabilization of firing up the controller gradually increases the amount of fuel fed.
This parameter is not available if the parameter STABILIZATION OF FIRING is set to
NO.

5.13 Furnace extinction (shut down) time – if the controller switches to extinction
(shut down) mode, the induction fan is activated according to power selected in „Fan
speed at extinction (shut down)” setting. After burner extinction (flame loss), the fan
operation follows according to time programmed in this setting. This function
ensures combustion of all fuel remains and burner cool down.

6.x Cleaning mechanism.

6.1 Furnace cleaning mode – this parameter specifies the way the cleaning

mechanism works:

NONE – means that the burner does not have a cleaning mechanism. In this case,
the output DATA is working as an external alarm.

CYCL – means the mode in which the cleaning procedure is run after the firing and
repeated at regular intervals until burner shut down is completed. Cleaning
procedure is attached to the time set in parameter „Cleaning mechanism work time".
After turning off the regulator, output deducts the time set in parameter „Cleaning
mechanism retraction time" and the time set in parameter „Cleaning mechanism
pause time".

ROTO – working mechanism ROTO mode is similar to mode CYCLE. The difference
is that the control output cleaning mechanism is attached for the duration of the
mode blanked.

AUTO – means the cleaning procedure is started automatically after a specified
number shut downs or after a sufficient burner operation time. Automatic cleaning
means: burner shut down and start cleaning mechanism for the time set in parameter
„Cleaning mechanism work time".

After turning off the regulator, output deducts the time set in parameter "Cleaning
mechanism retraction time" and then goes to normal working cycle.

COMBI – This mode is a combination of modes AUTO CYCLE. Working mechanism
starts at the end of the firing and stabilization is cyclical switching mechanism for the
time set in the parameter TIME WORK MECHANISM. After switching off the cleaning
mechanism controller counts down the time set in parameter RETURN TIME
MECHANISM, and the time set in parameter TIME PARKING MECHANISM. During
operation the output EXTINCTION cleaning mechanism is disabled. After a certain
number of extinctions or sufficient time, the burner is started automatically cleaning
involving extinguished hearth, start cleaning mechanism at the time set in the
parameter TIME OPENING THE MECHANISM and run the fan with the power
specified in the parameter SPEED FAN. THE CLEANING.
After switching off the engine output controller also disables the fan and counts
time set in the parameter TIME CLOSING MECHANISM, then take a normal job.

29

COMBI 2 – a mode similar to COMBI; the difference is that when the clearing device
is turned on, the blower always operates with the capacity programmed in the para­meter BLOWER SPEED RATE AT CLEANING, regardless of the current stage of
operations (except emergencies).

6.2 Cleaning mechanism work time – this parameter is available only when the
cleaning mechanism is activated (CYCLE, ROTO or COMBI. mode). It defines the
time needed to complete the full mechanism to open or move to end position.

6.3 Cleaning mechanism retraction time – this parameter is available only when

cleaning mechanism is activated (CYCLE, ROTO or COMBI. mode). It specifies the
time interval between successive repetition of the cleaning cycle.

6.5 Opening time cleaning mechanism – this parameter is only available when
cleaning mechanism operates in AUTO mode or ESTATE and determines the time
required to complete the opening mechanism during cleaning automatic.

6.6 Closing time cleaning mechanism – This parameter is available only when the
cleaning mechanism operates in AUTO mode or COMBI and determines the time it
takes to return the mechanism to its rest position after the full opening of the
automatic cleaning mechanism.

30

6.7 Number of extinctions before cleaning – this parameter is available only when
the cleaning mechanism operates in AUTO mode or COMBI and determines which
in turn goes off to start the procedure of cleaning.

6.8 Minimum operating time without cleaning – this parameter is available only
when the cleaning mechanism operates in AUTO or COMBI mode. Specifies the
minimum number of hours the burner must in order to start cleaning. If the minimum
time is not reached, the cleaning will not run even if there was a required number of
shut downs. Setting the parameter to „0h" control the minimum time off work without
cleaning.

6.9 The maximum working time without cleaning – this parameter is available
only when the cleaning mechanism operates in AUTO or COMBI mode. Specifies
how many hours the burner can work without cleaning. If the maximum time is
reached, the cleaning will run even if there was no required number of shut downs.

7.x Central heating pump work parameters.

7.1 Central heating pump switching on parameters – this parameter specifies the

method of central heating pump switching on. Selection of „THERMOSTAT” setting
means that central heating pump will be switched on only if room thermostat
contacts are closed and in case of emergency (e.g. boiler overheating). Selection of
„AUTO” setting means that central heating pump operation will follow regardless of
room thermostat.

7.2 Periodic switching pump – this parameter allows you to run the function
periodic heating pump to move water in the heating circuit. The pump is activated for
30 seconds at intervals set in the parameter TIME PERIOD. ON. PUMP CO. This
function is available when the CO pump mode is set to the value of TERM.

The controller offers an additional function for heating of domestic water. Not every
heating system is provided with domestic water tank and charge pump, this circuit
may be switched off or used for control of the pump that mixes the return water in
the boiler.

8.1 Domestic water path – if „NONE” is selected the domestic water pump is off. In
this case temperature sensor input and pump control output may remain
disconnected. Selection of „EXISTS” setting provides for interlock release of all
parameters and functions related to domestic water path handling. Election of
„MIXING PUMP” setting will switch domestic water in the circuit purposed for control
of the mixing pump. In this case return water temperature sensor shall be connected
instead of domestic water sensor, and the mixing pump instead of charge pump of
domestic water tank.

8.2 Domestic water heating hysteresis – this parameter indicates water

temperature drop in the tank in relation to the programmed setting (so that charge
pump was switched on). This setting is available, if domestic water path „EXISTS”
setting was selected.

32

8.3 Increase temperature during domestic water heating – Closing thermostat
contacts means that boiler operation will follow according to the temperature
programmed with the thermostat knob. If domestic water tank heating is necessary,
the desired boiler temperature is higher in relation to the desired domestic water by
the selected value in this setting. In case of simultaneous operation of the room
thermostat and domestic water tank heating, the controller operation will follow to
maintain the higher boiler temperature. This setting is available, if domestic water
path „EXISTS” setting was selected.

8.4 Domestic water pump work extension – quick switching off of the pump
refilling domestic water tank may result in excessive rise of boiler temperature. This
parameter enables switching on of domestic water pump extension. This setting is
available, if domestic water path „EXISTS” setting was selected.

8.5 Domestic water pump extension time – this parameter specifies the time lap­se when domestic water is switched off since the moment when the programmed
temperature of domestic water tank was obtained. This setting is available, if dome­stic water path „EXISTS” setting was selected and pump extension was selected.

8.6 The stabilization time after heating hot water – during the preparation of hot
water priority enabled all the power boiler is used to heat water. Temperature of the
boiler during operation for hot water is often higher than the required heating circuit.
In addition, the CH pump off when working with hot water priority can cause
hypothermia heated rooms and a room thermostat input activation. In this case, after
working for the hot water boiler water temperature may be higher than the
temperature required to heat the rooms. This may result in extinction of the burner
due to exceeding the hysteresis top of the boiler. This parameter specifies how long
is needed to stabilize the system after the hot water tank with priority enabled.
During the stabilization controller disable checking hysteresis top and suspend the
operation of the adaptive algorithm of the room thermostat. This parameter is
available only when hot water is on track.

33

CAUTION! This feature does not work if water preparation is done without priority or
the controller is in summer mode.

water temperature so that the mixing pump engagement follows the controller. This
parameter is available if domestic water path „MIXING PUMP” setting was selected.

8.8 Mixing pump work hysteresis – this parameter specifies required return water

temperature increase in relation to the mixing pump engagement temperature so
that the controller switches off the mixing pump. This parameter is available if
domestic water path „MIXING PUMP” setting was selected.

9.x Boiler work parameters.

programmed temperature setting which can be programmed with thermostat’s knob.
It is also boiler temperature when central heating pump is engaged to provide
protection for the boiler against overheating.

9.3 Boiler upper hysteresis – if the controller works in burner minimum power
mode, and boiler temperature increase follows by this programmed setting, the
controller will start burner extinction(shut down).

34

9.4 Burner power switching hysteresis – when the programmed boiler water
temperature is obtained the controller is switched to minimum power work mode.
This parameter specifies required water temperature drop so that maximum power
work mode was activated. After switching to maximum power the fuel and air feeding
dose is determined according to burner power modulation.

9.5 Boiler protection hysteresis – the controller provides for boiler minimum and
maximum temperature by providing control over operation of central heating and
domestic water pumps. This parameter specifies hysteresis parameter of boiler limit
temperatures switching off.

9.6 Boiler overheating temperature – this parameter specifies boiler water
temperature when the controller switches off control and activates boiler overheating
alarm.

9.7 Burner power modulation – when modulation is switched on it will results in
gradual reduction of fan speed and fuel dose to obtain boiler water temperature
corresponding to the programmed setting.

9.8 Burner power modulation factor – this parameter specifies degree setting
when the controller will reduce burner power before boiler water temperature is
obtained according to the programmed setting. Burner power is reduced by gradual
reduction of fed fuel dose and fan speed reduction. This parameter is unavailable, if
burner modulation power is off.

35

The room thermostat.

RK-2006LPG2 was equipped with an input for connecting any room thermostat with
contact output. Contacts of the thermostat is signaled by the appearance of the
thermometer symbol in the index of the thermostat.

CAUTION! The entrance of the room thermostat is active only during WINTER.
Lights up when the input state is independent of the mode setting.

9.9 Mode of operation of the room thermostat – this parameter determines the
impact of the entry of the room thermostat to the operation of the controller:

NORM. – in this mode, the thermostat contacts are closed when the controller starts
firing up the burner and the boiler strives to maintain the set temperature of the
boiler thermostat knob. After reaching the desired temperature in the room and the
thermostat regulator contacts open burner extinguishes and goes STANDBY.

ADAP. – in this mode, the controller analyzes the changes in the thermostat input
and based on automatically determines the setpoint temperature of the boiler.

Caution! In the case of not using the room thermostat input should remain closed,
and the operation of the thermostat set to the NORM .. In this case, the boiler will
operate continuously maintaining the set temperature of the boiler thermostat knob.

9.10 The time constant of adaptation – this parameter is available when the ther­mostat is working in adaptive mode. It determines the rate of "seeking" appropriate
adaptive algorithm preset boiler temperature. Value should be selected empirically
according to the characteristics of the controlled object. If you are working adaptive
algorithm and frequently changing external conditions we observe frequent overhea­ting of the rooms, increase the time constant. During niedogrzewania value should
be reduced.

9.11 Burner off delay – this parameter determines the time of the burner in
minimum power the thermostat contacts open. If, after the programmed time the
thermostat input will not be closed again, the torch will be lit, and the controller swit­ches to STANDBY. Setting this parameter to 0 minutes will immediately extinguish
the torch after contact opening
thermostat.
