The Vitoligno 300-P pellet boiler with three-pass principle fromViessmann sets new standards for heating with wood pelletswhere convenience, efficiency and safety are concerned. Devel-oped and built by Viessmann.Wide modulation range: The Vitoligno 300-P makes its casethrough efficiency and economical operation. For low energyhouses or buildings with a higher energy demand: With an outputrange from 4 to 48 kW and a high modulation ratio (1:3), it offers atailor-made solution for any heat demand and every aspiration.High efficiency: With its efficiency of up to 95% and its low fluegas temperatures from 125 to 135 °C, the Vitoligno 300-P com-mands one of the leading positions in the market. Combustion isconstantly monitored by a Lambda probe and a temperature sen-sor. This safeguards the permanently high efficiency and insensi-tivity to fluctuating pellet qualities. The large water content of theVitoligno 300-P makes thermal process protection superfluous.

Efficient partial load operation with Variopass: The three-passprinciple reduces the flow velocity of the hot gas in the first pass.In the second pass it directs the floating particles into the ash boxand expels almost dust free hot gas through the third pass.The new Variopass design principle matches the heating surfaceto the current operating state. A special mechanism automaticallyreduces the heating surfaces of the second and third hot gas fluein partial load operation, thereby assuring a very high utilisationlevel in all operating phases.Return temperature raising facility: The new Vitoligno 300-P oper-ates with low return temperatures. Reliability and a long servicelife are assured by the internal return temperature raising facility.An external return temperature raising facility is only required inheating systems with heating water buffer cylinder.

Design and function

Modular designThe control unit is integrated into the Vitoligno 300-P. It comprisesa standard unit, electronic modules and a programming unit.

Standard unit:& Standby switch& Emissions test switch& Optolink laptop interface& High limit safety cut-outDIN STB 116904

& Operation and fault displays& Wiring chamber– Connection of external equipment via a system plug– Connection of three-phase consumers via additional contac-tors

Programming unit:& Push buttons& Illuminated display with plain text prompts& Digital time switch& Adjustment and display of temperatures and codes& Fault message display

Functions& Weather-compensated control of the boiler water and/or flowtemperature

& Electronic maximum and minimum temperature limit& Control of two heating circuits with mixer or one heating circuitwith mixer and one solar circuit

& Option to regulate a heating water buffer cylinder& Demand-dependent heating circuit pump and burner OFF con-trol

& Adjustment of a variable heating limit5822413GB



& Anti-seizing pump protection& Integral diagnostic system& Service display& Adaptive cylinder temperature control unit with priority control(heating circuit pumps OFF, mixer closed)

& Auxiliary function for DHW heating (short-term heating to ahigher temperature)

& Screed drying, for underfloor heating systems& Control of a solar circuit as alternative to the second mixer cir-cuit.

The requirements of DIN EN 12831 for the heating load calcula-tion are met. To reduce the heat-up load, the reduced room tem-perature will be raised in case of low outside temperatures. Theflow temperature will be raised for a limited time to reduce theheat-up time after a setback period.According to the Energy Savings Order [Germany], the tempera-ture in each room must be individually controlled, e.g. throughthermostatic radiator valves.

Control characteristics& Boiler control unit:PI characteristics with modulating operation

& Heating circuit control unit:PI characteristics with three-point output

& Thermostat for limiting the max. boiler water temperature:85 °C

& Adjusting the high limit safety cut-out:95 °C

& Heating curve setting range:– Slope: 0.2 to 3.5– Level: -13 to 40 K– Max. limit: 20 to 130 °C– Min. limit: 1 to 127 °C– Differential temperature for a heating circuit with mixer: 0 to40 K

& Range of the set DHW temperature10 to 60 °C, may be changed to 10 to 75 °C

Boiler coding cardFor matching to the boiler (integrated).

Time switchDigital time switch& Individual and 7-day program& Automatic summer/winter time changeover& Automatic function for DHW heating and DHW circulation pump& Time, day and standard switching times for central heating,DHW heating and the DHW circulation pump are factory-set

& Switching times are individually programmable, i.e. up to fourswitching periods per day

Shortest switching interval: 10 minutesPower backup: 14 days

Setting heating programsThe heating system frost protection (see frost protection function)applies to all heating programs.The heating programs are selected via menus. The following heat-ing programs can be selected:& Heating and DHW& DHW only& Standby modeExternal heating program changeover

Summer mode("DHW only")The burner starts only when the DHW cylinder needs reheating(controlled by the cylinder thermostat).The respective lower boiler water temperature of each boiler ismaintained.

Frost protection& The frost protection function will be started when the outsidetemperature drops below approx. +1 °C.With the frost protection activated, the heating circuit pumps areswitched ON and the boiler water is heated to the set value forreduced mode, but is held at least to the lower temperature limitof approx. 20 °C (the lower temperature is maintained for boilerswith lower temperature limit).

& The frost protection function will be switched OFF, when the out-side temperature exceeds approx. +3 °C, i.e. the heating circuitpump and burner will be switched OFF.

Adjusting the heating curves (slope and level)The Vitotronic 300, type FW1 controls the boiler water tempera-ture and the flow temperature of the heating circuits with mixer inweather-compensated mode. The boiler water temperature isautomatically boosted by between 0 and 40 K higher than the cur-rently required set flow temperature (delivered condition 8 K).The flow temperature required to reach a specific room tempera-ture depends on the heating system and the thermal insulation ofthe building to be heated.Adjusting both heating curves matches the boiler water tempera-ture and the flow temperature to these operating conditions.The upper boiler water temperature is limited by the electronictemperature limiter and the electronic maximum temperature limit.

Selection of rated output

When selecting a boiler size, the [German] Energy Savings Orderprescribes that the rated output according to EN 12831 orÖNORM M 7500 does not exceed the calculated heat demand.

Fuels

This boiler is only approved for the combustion of commercial,natural wood pellets (max. residual humidity 7 to 12%, diameter 6mm, length 5 to 30 mm acc. to DINplus or ÖNORM M 7135).Pellets must be transported and stored in absolute dry condition.

The following are unsuitable types of fuel:Fossil fuels and those containing sulphur, such as anthracite,coke as well as plastics, grain, chipboard, material soaked in flam-mable liquids, wood chips, sawdust, wood dust or wood and wastewood treated with plastics or wood preservatives.

Hydraulic connection

Never use solid fuel boilers in open heating systems to DIN EN12828. Instead, integrate these boilers in sealed systems to DINEN 12828 , as shown in the installation examples in the technicalguide.Only connect regulated heating circuits with mixer.

Systems without heating water buffer cylinders generally requireno return temperature raising facility, as the Vitoligno 300 isequipped with its own integral return temperature raising facility.Systems with a heating water buffer cylinder require both a shuntpump and a return temperature raising facility.

DHW heating

The DHW cylinder primary pump will only be started when theminimum boiler water temperature of 50 °C has been exceeded.

Safety equipment

The boiler should be equipped with a type-tested safety valve(subject to design) in accordance with DIN EN 12828 for DHWheating systems with a safety temperature of up to 110 °C.This valve must be identified in accordance with TRD 721, i.e.with

& "H" up to 3.0 bar permissible operating pressure and max.2700 kW rated output,

& "D/G/H" for all other operating conditions.

Low water indicator

DIN EN 12828 specifies the use of a low water indicator (availableas accessory).

Flue gas system

Connect the Vitoligno 300-P to highly insulated chimney stacks(thermal resistance class I to DIN 18160-1) or use suitable moist-ure-resistant flue gas systems that have Building Regulationsapproval.Install no more than one 90° bend in the flue pipe to safeguardoptimum combustion. Route the flue pipe into the chimney stackwith an incline (at least 10°, optimum inclination = 45°).Prevent any reductions and additional bends, otherwise the lowpressure inside the chimney may be insufficient for trouble-freeflue gas removal. The combustion could then be impaired.The flue pipe up to the entry into the chimney stack may be a up to3 m long. Insulate the flue pipe over the entire length with at least30 mm thick thermal insulation; the flue pipe must be sound.Install a draught limiter.

Flue gases must be routed from the chimney to the outside in amanner that prevents damage from the precipitation of vaporousflue gas components inside the chimney.Boiler and flue system must be matched to each other; this appliesparticularly to older systems that are being modernised. Preventchimney damage through the following steps (check with yourlocal flue gas inspector):Install a draught stabiliser into the chimney side, thermally insu-late the flue pipe, thermally insulate the chimney in unheatedattics or modernise the chimney.

Sound insulation

Never grout the flue pipe into the chimney to prevent sound trans-mission caused by the induced draught fan.An anti-vibration joint for fitting into the flue is available as acces-sory.
