  • Page 6 Dear customer, Dear heating technician, The controller LambdaControl 2 BSB® is the result of many years of research and resultant knowledge of Logotherm. It contains the latest innovations in combustion and system technology and offers the highest level of quality and perfection.
  • Page 7 Load valve ≤ smaller than or the same as ≥ greater than or the same as < smaller than > greater than Lambda (air ratio) λ Display and operating element Display 1: Shows the operation mode of the wood boiler – when lit “Boiler ON”. Display 2: Refuel signal.
  • Page 8 Please follow the displayed instructions. If the refuel program was activated by mistake, press button 9 (►) to deactivate it. Once the required flue gas temperature is reached an audible alert sounds to indicate that the door(s) need to be closed. Then “Display 1” illuminates – “Boiler ON”. Please follow the displayed instructions.
  • Page 9 AAO: Combustion and Burnout Optimisation Alongside with BSB, AAO is the most important function. It regulates fuel properties, which are not always ideal in practice. Note: This basic function cannot be activated or deactivated manually. When AAO is activated displays. Effect: If the combustion temperature is too low, the controller automatically increases the boiler output to meet the minimum combustion temperature required.
  • Page 10 “Accumulator” → “Information” → HC-release PAE contains three functions with different effects: ® Function 1: Heating demand limiter of the heating circuits regulated by the LambdaControl 2 BSB Function 2: Hot water preparation when “Acc. t.-F4” > 60°C Function 3: When the hot water preparation is ON, but the increase in temperature is not enough for the hot water tank.
  • Page 11 Function 3: Note: Function 3 can be deactivated as follows: “Hot water” → “Settings” → 12.08 HW priority. If the setting is YES, function 3 is activated. Use: Function 3 ensures that the hot water preparation is possible and not carried out with a too low transmission capacity.
  • Page 12 1.11 BSB: Basic Principles BSB requires the accumulator sensors F5 (1-4). These sensors are used to calculate the correct refuel amount. The displayed fuel amount is dependent on the boiler operating status (“Boiler ON/OFF”). Operating status “Boiler OFF”: In “Boiler OFF” the refuel amount is only displayed, if the for AFO required fuel amount can be added. The time of the display of the fuel amount depends on the “AFO runtime”...
  • Page 13 ABO YES should only be selected, if: the boiler and chimney are suitable ( low flue gas temperature); a Logotherm conform hydraulic system with proper sensor adjustment is used. 1.15 Minimum Flue gas Temperature Note: The controller strategy is to burn at rated power, except for the functions KLA and ABO.
  • Page 14 temperature is set ≥ the required flue gas temperature for the rated output of the boiler type, KLA loses its effect; is it set higher than the boiler rated output x 1.25, SLA is switched off as well. If 5.13 Flue gas min. is increased substantially, the accumulator volume must be checked. If it is too small, the refuel amount is reduced, since the heating demand would become insignificant compared to the higher boiler output.
  • Page 15 1.18 Integrated fuel types Different types of wood, i.e. birch, spruce, beech etc., have different densities, resulting in different heating values. The following values can be used as a guideline: D = Density in %; Hu = Heating value kWh/kg; w = Water content in % Type of Wood Hu kWh/kg Type of Wood...
  • Page 16 1.19 Water content – moisture content of fuel Generally a wood boiler can burn wood in its natural form, if its water content (w) is lower than 20%. A high moisture content in fuel can lead to complications while burning and reduces the efficiency of heating and the dispensed amount of energy.
  • Page 17 Therefore the setting in “Accumulator” → “Settings” → 9.02 Acc. reserve should only be set to 0%, if the sensor positioning is Logotherm conform – and only if no backup for heating or solar is needed. In numbers: Boilers with a rated output of 20 kW to 30 kW usually have a fuel chamber that can hold an energy amount of approx.
  • Page 18 All applicable norms and standards are met. The system was commissioned by a certified furnace technician. The boiler name (type) is stored in the LambdaControl 2 BSB®. Minimum requirements for a trial run or heating test The following conditions must be met to conduct a test run: The flue gas pipe must be connected dust- and gas-proof to the chimney, the flue gas system must be unobstructed –...
  • Page 19 Possible settings: “YES” / “NO” / “BUS”. ® YES: If the sensor is installed at the LambdaControl 2 BSB BUS: If the temperature of the sensor is requested over the CAN-bus. The outside sensor is required for the regulation of the heating circuit.
  • Page 20 Outside sensor No. Possible settings: “1” / “2” / “3” / “4”. This setting is important if the sensor is required for other Logotherm control devices. The outside sensor is required for the regulation of the heating circuit. DCF77-Receiver Possible settings: “YES” / “NO”.
  • Page 21 Numbering of the controller if several LambdaControl 2 BSB - controllers are on the bus. Be mindful that the set Bus No. was only allocated once per LambdaControl 2 BSB®. Note 26.33 Note: Fuel that is too large or too wet.
