Summary of Contents for KEY RK-2006LSPz

  • Page 1 OPERATION MANUAL RK-2006LSPz AUGER FITTED SOLID FUEL BOILER TEMPERATURE CONTROLLER Version C820...
  • Page 3 1. Application. Controller RK-2006LSP is designed for temperature control of solid fuel fired water boilers equipped with:: - Auger and feeding stoker working with the stoker, - Blow-in fan, - Ignition glow plug for automatic start, - Central heating pump, - Hot tap water pump or mixing pump (option), - Alarm indicator or or ash removal system (option), - Room thermostat (option).

  • Page 4: Operation

    3. Operation. After turning the controller on, the name and software version is displayed and all signal lamps are on to enable checking of functionalities. When the controller is turn on it will return to its last state before turning off or power failure. On the front panel of the controller (Figure 1) there is: 1 - Display, 2 - Fan indicator,...
  • Page 5 3.1. Main window, adjustment mode and devices mode. Following turning on of the controller the main window is displayed. On the top of the display (1) boiler water temperature is shown, and on the bottom operation mode is displayed. Symbol „*” displayed in the right bottom corner indicates burner flame detection.
  • Page 6 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 (10) will result in switching the controller to STAND-BY mode.
  • Page 7 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.
  • Page 8 3.3. ALARMS. RK-2006LSP controller continually checks operations of installed devices as well as alarm sensors. In case of failure, the device activates alarm and proper operations 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.
  • Page 9 Auger sensor damage. In case of auger temperature sensor damage, as in case of overheating, the controller will go to shut down mode and will activate the appropriate alarm: A L A R M : A U G E R T E M P .
  • Page 10 Domestic water temperature sensor damage. If the heating system is fitted with domestic water circuit, in case of sensor damage the controller turns off the domestic water pump and activates alarm: A L A R M : H O T W A T E R T E M P .

  • Page 12 4.4. Domestic water circuit operation parameters. These parameters specify how the controller ensures domestic water temperature. In case of the system without domestic water circuit, it is not possible for the user to view and change these parameters. Domestic water desired temperature - parameter that specifies temperature of water in domestic water tank that will be obtained by the controller.
  • Page 13 4.6. Flame optical detection parameters. These parameters specify operation of burner flame optical detector. If the system is fitted with flame temperature detector, parameters change and viewing is unavailable. The current furnace brightness determined by an optical detector - this parameter displays the current flame brightness measured by the optical detector.
  • Page 14 Burner start up counter. Reading of this counter defines start number of the ignition attempts. B U R N E R S T A R T C O U N T 5. Settings – service mode. Holding OK button for 3 seconds enters the service mode where you can review and change the parameters by pressing the selection buttons (8 and 11).

  • Page 16 M I N . F A N S P E E D H E A T I N G 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.
  • Page 17 Fan speed during cleaning mode - only when AUTO is on. F A N S P E E D D U R I N G C L E A N I N G 1 0 0 % Fan scavenge (air purging) - the controller offers the function of scavenge (air purging), which simply includes periodical switching on of the fan during burner operation for the purpose of removal of accumulated gases.
  • Page 18 Fuel feed cycle - auger operation cycle includes fuel feeding and feeding pause. This parameter specifies the time of the whole cycle. The desired value specifies all burner work modes which require fuel feeding (ignition, maximum and minimum power). F U E L F E E D C Y C L E 1 5 s...
  • Page 19 Stoker pause time - this parameter specifies pause time during stoker operation when in work cycle. This setting is unavailable if the stoker is switched off or in automatic mode. S T O K E R P A U S E T I M E Stoker extra work time - this parameter is available only, when the stoker works in automatic mode and it specifies stoker work time after auger switching off.
  • Page 20 5.4. Fuel ignition, extinction (shut down) and cleaning combustion chamber. Flame detector - flame detection may follow 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.
  • Page 21 F U E L I G N I T I O N T I M E 3 m i n 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.
