 Controller:
-Application
RK-2001W controller is a device designed for temperature control of solid fuel fired
boilers. The temperature of the boiler is kept on level set by the user by controlling
the speed of the blow-in fan. The controller constantly monitors the temperature of
water in the boiler, shows it on the display and controls the central heating pump.
To enable more precise temperature control of heated rooms the controller has
been equipped with an input for room thermostat connection. The controller also
enables controlling of the hot water tank pump.
In case of no fuel, the controller has an option to turn on gas or oil boiler (additional
option).
-Connection
Before turning on the controller by master switch, connect controller, fan and the
central heating pump power leads to appropriate sockets in the rear of the
controller. The temperature sensor should be placed in a measurement hole in the
boiler.
CAUTION! Before plugging in the controller check if the wiring system is properly grounded and
if the terminal screws of the output connector are properly screwed.
CAUTION! A fan and a central heating pump of maximum power of 450W can be connected to
the controller.
CAUTION! As additional option you can connect the UM-1 module to the controller that allows
controlling the additional boiler or the mixing valve and the hot water loading pump. It is
necessary to protect the power supply of these devices with suitable cut-outs.
Outputs of the controller that are not used may remain unconnected.
-Operation
After turning the controller on all the elements of the display are lit for a while to
check if they are working properly. The controller, when power appears, returns to
its last state before turning off or power loss.
Front panel of the controller (Pic. 1) consists of:
1-Master switch
2-Display, indicating boiler temperature and parameters
3-Room thermostat indicator
4-Boiler thermostat knob
5-Central heating pump work indicator

6-STOP/choose parameters/erase alarms button
7-START/choose parameters button
8-Start programming /confirm parameters settings button
9-Hot water pump work indicator
Picture 1. Front panel of the RK-2001W controller
Basic operation of the controller is carried out by setting the desired temperature
with boiler thermostat knob, other functions are carried out according to parameters
programmed in service mode. The change in the boiler temperature setting is
shown on the display for a few seconds, e.g. [C 55] and this value means the
temperature of the water in the boiler which the controller will be trying to achieve.
You can also check this value by pressing OK button for a short time. After
pressing START button the fan starts to work and the control process begins.
STOP button stops the fan for example to add fuel.
If the controller is not in user or service mode the display shows water temperature
in the boiler and the last character on the display defines the mode which the
controller is currently in:
for example: [50º-] - STOP mode
[50ºC] - WORK mode
[50ºc] - hold up of burning in WORK mode
[50ºU] – heating of hot water in SUMMER mode
[50°u] - hold up of burning in SUMMER mode
[50ºd] – total bacteria control – heating up of hot water up to
75ºC.
-Settin up the user parameters.
Holding OK button enters the user mode and allows reviewing and is indicated by
fast flashing of the room thermostat indicator. You can look through the parameters
with < and > arrow buttons. After choosing the desired parameter you can switch to
the change mode of the parameter by pressing OK button - it is indicated by the
value of the parameter flashing.
Change of the parameter is done by pressing - or + buttons. You can confirm new
settings by pressing OK button and after that the controller allows choosing another
parameter (with < > buttons). If you do not want to change the parameter value
with the < or > button choose [End] and press OK or wait for 1 minute – the

1. Boiler work temperature
The boiler set temperature [C 40] – is the temperature which the controller will try
to achieve in WORK mode.
It is set by direct turning of the knob and is indicated by a short display.
2. Central heating pump work [co C] – WINTER/SUMMER mode –
character “C” indicates that the central heating pump is working. In summer time
the heating can be turned off by choosing the value “-“ with the (-) button which
means turning off the central heating pump.
3. Total bacteria control in the hot water tank – heating up - the
controller allows to manually launch the total bacteria control process in the boiler.
Choosing the “d” value with (+) button starts the process in which the boiler is
trying to achieve the temperature of 75˚C in the hot water tank. In order to start the
total bacteria control process the boiler should be in WORK mode (this mode can
be turned on by START button). E.g. [70˚d] will appear on the display. After
reaching 75˚C in the hot water tank the controller will return to its state before
choosing this option.
CAUTION: the total bacteria control function can switched on at night when the water from the
hot water tank is not used to prevent the users from burn injury.

In the table above, the first column represents example display indications, in the
next columns there are: parameter description, minimum and maximum values
allowed to set, step of the parameter during the setup. The last column shows
factory defaults to which you can return by choosing [Prod] option.
1. Fan work parameters
Fan power [Π100] - this value defines power of the fan. When "Πr" parameter is set
to "0-10" this is the maximum power of the fan which can be achieved during
automatic fan control.
Automatic fan speed control [Πr 1] - it is on, when this parameter is set to "0-10"
and causes automatic fan speed decrease when temperature of water in the boiler
reaches desired temperature. If this parameter is set to "-", the fan automatic
smooth speed control is disabled and the fan can work with power set by "Π"
parameter. Setting parameter value in range from 0 to 10 means time in minutes of
the smooth fan speed increase from 40% to value of "Π" - for smooth boiler start.
Fan work time [Πr 1] - time of turning the fan on for a while, to remove accumulated
gases. Setting the parameter to "--" turns this function off. This function can be
active in WORK mode.
Fan pause time [Nu 6] - time between fan work periods
2. Central heating pump work parameters
Central heating pump launch temperature [P 40] – the value of temperature of the
water in the boiler which causes start of the central heating pump. Central heating
pump works independently from the control process and is launched additionally in
case of boiler overheat.
Central heating pump launch hysteresis [Ph 2]- this parameter defines what value
should the boiler water temperature decrease by, below the launch temperature, so
that the pump turns off.
Repeat launch time of the central heating pump [Pc 2] - in STOP mode or when
room thermostat circuit is open, the central heating pump is launched for 30
seconds to mix water in heating circulation. This parameter defines the repeat time
of launches of the pump.
Setting the parameter to "--" turns this function off.
3. Preparation of domestic hot water
The controller has additional output allowing to control the hot water tank loading
pump by the UM (UM-1) module.
The hot water temperature [u50] – temperature value which will be kept in the hot
water tank. The heating hysteresis of the hot water heating [uh5] – value which the
temperature in the tank has to decrease by so that the hot water pump turns on in
order to heat up the water in the tank.
Parameter [ur 1] – the [ur 0] value indicates no sensor or hot water pump. The
sensor is not taken into account in testing failures, i.e. it can remain unconnected

- 15
-
and in the user parameter menu there is only the boiler thermostat set temperature
displayed.
[ur 1] value – hot water pump working with priority
[ur 2] value – hot water tank working without priority
[ur 3] value- means controlling of the returning water mixing pump in the boiler with
the launch temperature of [u 50] and hysteresis [uh 5].
4. Setting of boiler work temperature range
Minimum boiler temperature [L 40] - minimum temperature which can be set with
the boiler thermostat knob.
Maximum boiler temperature [H 90] - maximum temperature which can be set with
the boiler thermostat knob.
Boiler temperature hysteresis [h 5] - this parameter defines what value should
temperature of water in the boiler decrease by, below temperature set with the
thermostat knob, so that the fan turns on.
5. Protection against boiler overheating
Boiler overheating temperature [A 99] - value, exceeding which causes permanent
turn off of the fan to prevent boiler overheating. After the temperature increases
above 80˚C the central heating pump is turned on to cool down the boiler.
Overheating mode is shown by indicating error [E 2] on the display. It can be
turned off by pressing STOP button, but only when temperature decreases below
this temperature.
Fan turn off also occurs in case of damage of the boiler temperature sensor which
is shown on the display with error [E 1].
STB - the controller has additional protection against overheating which is
independent from the processor. In case the temperature increases over 95°C, the
control process is turned off by turning the fan off and launching the central heating
pump. The fan and the pump are turned on to the control process again when
temperature drops below 89°C.
STB circuit enables more precise boiler work control and reduces overheating
possibility.
6. No fuel
No-fuel testing time during fuel firing start [Fd60] - after switching to WORK mode,
if water temperature does not increase by 5°C in programmed time, the control
process will be turned off and the display will show the message: [FUEL].
You can return to previous mode by pressing STOP button. No fuel testing time
during fuel firing is finished after the set temperature is achieved.
No-fuel testing time during work mode [Fb30] - in WORK mode, if temperature of
water in the boiler decreases below temperature set with the thermostat, by
hysteresis value, and does not increase by 5°C in the programmed time, the
control process will be turned off and the display will show the message: [FUEL].
You can cancel the alarm by pressing STOP button.
7. Additional output

- 16
-
Additional output [Ar 0] – the controller has been equipped with an output that
allows connection of the UM module. When the Ar parameter has the UM module
value “0” it may control the oil or gas boiler – if such boiler exists in the heating
circuit. After switching the controller with the main power switch the additional
boiler is turned off and it turns on again when there is no fuel in the solid fuel boiler.
This function is useful in heating systems where there is a solid fuel boiler used to
cut the heating costs. After erasing the “no fuel” alarm by pressing STOP button
the additional boiler is again turned off and the controller works again. Setting
parameter [Ar] to “1” allows controlling the additional alarm signaling system with
the UM module – which occurs on the controller.
When Ar parameter is set to “2” the UM module allows controlling the mixing valve
servo-motor in the central heating circuit depending on the room thermostat input.
In this case the work of central heating pump depends only on the boiler
temperature.
8. Factory defaults
The controller allows returning to standard settings set by the producer by choosing
[Prod] and pressing OK button. After activating this function, the controller sets
each parameter showed in the table.
9. Output testing
To make checking the controller work easier, it is possible to test output circuits
which control the fan and the pump, and the additional boiler launching system.
This function is available in service mode, only if the control process is off, i.e. the
controller was in STOP mode before switching to service mode. By choosing [outP]
on the display and pressing OK button you can turn on the central heating pump for
a while, by choosing [outΠ] and pressing OK you can turn on the fan and by
choosing [outr] and pressing OK you can turn the additional boiler on (if the
additional module is connected). Choosing [outu] allows testing the hot water pump
output.
10. Exiting service mode
By choosing [End] option on the display and pressing OK button you can exit
parameter setting mode.
The controller also exits service mode, when no buttons are pressed for 1 minute.
-Additional functions
To improve comfort in heated rooms, the controller has been equipped with an
input that allows connecting any kind of room thermostat with contact output. When
temperature in the room is below desired temperature, the central heating pump is
turned on and the room thermostat indicator is lit.
It means that the boiler should keep temperature set by the room thermostat knob.
After reaching desired temperature in the room, the room thermostat indicator turns
off, the central heating pump is turned off and the boiler switches to mode in which
it keeps burning at minimum temperature.

- 17
-
CAUTION. In case of not having room thermostat in the system, the room thermostat input
contacts must be short-circuited.
-Controller failures
The controller is constantly testing if its internal circuits and temperature sensor are
working correctly. After detection of fault, it stops the fan, turns on the central
heating pump and shows proper error message on the display. In case of failure
please turn off the controller, plug the central heating pump to the power source,
ensure appropriate fuel firing in the boiler and contact the service.
When [E 1] error appears on the display, it means fault in the boiler sensor circuit
or temperature below 0°C. [E 2] is displayed if boiler overheats. [E 3] error means
fault and overheating at the same time. Appearing of [E 1] error on the display after
erasing it by pressing STOP button, in spite of temperature decreasing below
90°C, may mean permanent damage of boiler temperature sensor (e.g. if the boiler
has been overheated above 150°C). In case of programming the sensor and
central heating pump in the service mode the controller tests the hot water sensor
circuit. Appearing of fault [E8] means damage or lack of hot water sensor.

6.1) Standards
•Heating System – during installation and operation of the boiler it is very
important to keep safe distance from the inflammable materials. The boiler is
allowed to work only in open type heating systems!
•Electrical installation – the boiler’s power supply is 230V/50Hz
•Chimney – It must be done with respect to current norms and regulations.
Due boiler gasses temperature 90-100 C it is obligatory to put the INOX or
other material tubes into the chimney. Required chimney draught is 0,1 –
0,2 mbar. Installation according to ADJ does entail some testing of the
chimney, which may be carried out by a sweep

6.2) Localization of the boiler:
•Placing on flammable foundation.
•place the boiler on non-flammable and thermal insulating pad which should protrude
not less than 20 mm outside boiler’s dimensions;
•If the boiler is located in the basement it is required to place it on a base raised not
lower than 50 mm over floor’s level. The boiler and the fuel hopper must stand
vertically and can be leveled using the regulating screw in fuel hopper’s leg.
•1 000 mm of free space must be left in front of the boiler.
•Minimal distance between back wall of the boiler and boiler room’s wall is 400 mm.
•Minimum distance between free side of the boiler and boiler room’s wall is 100 mm.
•The (230V/50Hz) electric socket should be easy to access.

6.3) Ventilation:
Appropriate supply and exhaust ventilation must be provided in the boiler room.
Accordantly with regulations each
boiler room has to have the
ventilation inlet and outlet in aim
of assurance of correct boilers
work and users safety. Lack of
ventilation inlet or it’s stocking is
the most frequent cause of
incorrect work of boiler ( the
fumidity, condense water,
impossibility of higher
temperature obtainment).
Ventilation outlet has instead in
task of offtake from room used air
and harmful gases. In boiler room
with chimney with natural draught
it is not it allowed to use
mechanical ventilation.
6.4) Chimney connection:
1. Cleaning door (Revision door)
2. Insulation.
3. Flexible connection (It should be
45°)
Chimney should be done from
the steel >3mm.
