This brochure provides you with all you need to know about the current product range, accessories and service.Durable in use – easy to maintainWhich system for which application?Centralised ventilation in new buildingsDecentralised ventilation for existing buildings and modernisation projectsReliable, durable technology – it's essentialMechanical ventilation systems for every demand:Appliances for centralised and decentralised mechanical ventilationReliable air distribution with practical duct system2/3Controlled mechanical ventilation ensures a comfortable ambience and protects the fabric of the buildingIn recent years, more stringent building regulations have led to sustainable energy savings, particularly in the construction of new houses and apartments. For example, in existing housing, the annual heat demand for a detached house is approx. 200 kWh/m2. For a comparable new house, built in line with the new 2014 Energy Savings Ordinance (EnEV [Germany]), this annual heat demand is only around a quarter of that ?gure.Use of new building and insulating materials results in an airtight construction that no longer provides the necessary minimum air change rate in the interior.Controlled mechanical ventilation for a consistently sound room air qualityAn adequate air change rate is essential for health and well-being, as well for protecting the fabric of the building. The answer is a mechanical ventilation system: It provides the air change rate that is required and regulates humidity levels in the interior. Such a system prevents mould growth and ensures the controlled replacement of stale indoor air with fresh, ?ltered outdoor air, thereby providing a comfortable ambiance for residents and protection for the fabric of the building. Controlled mechanical ventilation continuously extracts stale air from, for example, bathrooms, kitchens and toilets, and replaces it with fresh air in living areas, playrooms and bedrooms. This ensures consistently high air quality.In an average detached house, up to 15 litres of humidity are transferred to the indoor air every day. An amount accounted for in less than a minute when showering. In older buildings, this humidity condenses at cold points on the walls, resulting in a risk of mould growth.In the past, this problem was contained by natural ventilation through draughty door and window frames. However, such draughts no longer arise in energy efficient new buildings and existing buildings modernised in line with EnEV speci?cations.Moisture damage needs to be prevented by means of controlled ventilation.Legal requirements stipulate a minimum air change rateEnEV speci?cations go so far as compelling building owners to guarantee an adequate minimum air change rate in their buildings. Residents are usually out of the house during the day, which means that the necessary ventilation does not take place.A mechanical ventilation system operates continuously, thereby preventing adverse effects for residents as well as damage to the building.Allergy sufferers can breathe more easilyAllergy sufferers really appreciate mechanical ventilation systems: Fitted with effective pollen ?lters, they reduce the pollution level so those affected suffer less from allergic reactions, while still being able to breathe fresh air.Humidity is released here: Up to 15 litres a day in a 4-person household.180 C20:052-3 20 052-340 C1-282 litres per day 2 to 4 litres per day2 to 8 litres per day 1 litres per day4/5New buildCentralised ventilation in new buildingsIt is now often the case that modern buildings are already equipped with mechanical ventilation systems. On the one hand, this requires a high level of energy insulation in order to regulate indoor air humidity as effectively and reliably as possible. On the other, it is regarded as a comfort feature for well equipped apartments or buildings.Mechanical ventilation in detached housesThe installation of mechanical ventilation systems in new detached houses is already standard, especially in low energy and passive houses.Consequently, no heat is lost through accidental ventilation in the colder months and the continuous air change ensures a consistently high level of indoor air quality.Heat recovery from extract airAdvanced mechanical ventilation systems are particularly energy efficient: A powerful heat exchanger recovers up to 98 percent of the latent heat contained in the extract air and uses it to heat incoming fresh air. This reduces household expenditure perceptibly thanks to a signi?cantly lower energy demand. Furthermore, CO2 emissions are reduced.Every new building equipped with mechanical ventilation has a central unit that supplies all rooms with fresh air via a duct system. In most cases, the duct system is concealed in the ?oor or integrated into the walls. Only the air vents remain visible. The air change rate is regulated automatically by the central ventilation unit.Vitocal 343-G heat pump with Vitovent 300-F: A central mechanical ventilation system is now standard in new buildings.6/7ModernisationMechanical ventilation unit in a modernised older buildingDecentralised ventilation for existing buildings and modernisation projectsEver rising energy costs have encouraged the housing industry to bring existing buildings up to current energy standards. The old housing stock is being modernised comprehensively and now offers its residents such comforts as new, energy efficient windows and doors, wall insulation or a new heating system with convenient domestic hot water provision.Risks associated with modernisationModernisation also results in older apartments being so airtight that no adequate fresh air exchange can take place. The consequence is high humidity levels in the interior, which can lead to mould growth, especially in buildings with insulated walls. Areas that are particularly at risk are the corners of rooms next to external walls, as this is where humidity condenses.A central ventilation system can be ruled out in most existing buildings, since there is frequently insufficient space to install ventilation ducts in the interior. A decentralised system with heat recovery is the most suitable solution in this case.Ventilating rooms individuallyDecentralised ventilation units can be installed purposefully in individual rooms. All that is required for a straightforward installation is a wall opening or a hole through the exterior wall of the respective room and a 230 V power supply. No ventilation ducts need to be installed for this system.Residential units can be equipped with several units that operate independently from each other. These are ideal for providing a comfortable ambience with the required minimum air change rate. These units feature a heat recovery level of up to 90 percent.Use of decentralised mechanical ventilation units in existing buildings8/9Reliable, durable technology – it's essentialViessmann mechanical ventilation systems are characterised by their innovative technology. They are durable, reliable and operate particularly quietly. With different equipment levels, they can be employed ?exibly in the widest range of applications imaginable, no matter whether in a new building or for the modernisation of an existing building. Overview of technology and functionsCO2 and humidity controlAir is considered to be fresh when the CO2 concentration is below 0.1 percent by volume and it is as free as possible from odours. Vitovent systems exchange the air continuously to create a pleasant and healthy ambience. They remove odours and noxious substances, replacing more or less air depending on the prevailing humidity levels, thereby removing humidity (subject to outdoor air humidity and weather conditions). Bypass function for cooling in summerDuring the warmer months of the year and depending on outside and room temperatures, the fresh night air can be used for cooling the interior. For this purpose, the outdoor air is routed past the cross-countercurrent heat exchanger by a bypass.On the Vitovent 300-W, Vitovent 300-F and Vitovent 300-C, the bypass dampers are controlled automatically subject to outside temperature. Cross-countercurrent heat exchanger for heat recoveryIn accordance with the countercurrent principle, the heat exchanger utilises up to 98 percent of the heat in the extract air. This saves on heating energy and helps to protect the environment.Heating passive houses with warm airIn a passive house, a combination of a Vitovent 300-F and a Viessmann compact heat pump can be used for space heating. A hydraulic reheater coil for temperate heating with up to 1.5 kW output is available from the range of accessories. In addition, an optional heating water buffer cylinder with a capacity of 25 litres is integrated into the Vitovent 300-F. Air ?ow rate for a constant air changeContaminated ?lters present greater air resistance. Central ventilation systems make automatic readjustments to ensure that the necessary air volume for comfort and hygiene is still supplied and extracted at all times.Central mechanical ventilation units control a constant air ?ow rate internally. This ensures that the required ?ow rate is always delivered, even with variable degrees of ?lter contamination.Automatic ?lter monitoring The integral ?lters comply with strict requirements. They must ?lter dust and pollen reliably from the fresh air. Vitovent 300-F and Vitovent 200-D are both equipped as standard with an integral pollen ?lter. F7 grade ?lters are available as options for alternative ventilation units. Regular ?lter changes are required to ensure that everything runs smoothly. The active monitoring system indicates the need for replacement in good time.Temperature curve in the corner of a room – this is where condensate can formSupply airOutdoor airExtract airExhaust airFunction of the integral bypass damper: Fresh outdoor air (green) is routed past the cross-countercurrent heat exchanger.Outstanding qualityCross-countercurrent heat exchanger in the Vitovent 300-WDust and pollen are ?ltered reliably Continuously operating decentralised ventilation unit Vitovent 200-DJust one unit for supply and extract airIn order to ensure continuous operation, the Vitovent 200-D decentralised ventilation unit is equipped with two integral fans – one for supply and one for extract air. Heat is recovered by means of a cross-countercurrent heat exchanger. This turns the Vitovent 200-D into a complete ventilation system with heat recovery, which can be used for single room ventilation.10/11Mechanical ventilation systems for every needCentral mechanical ventilation unitsVITOVENT 300Wall mounted, mechanical ventilation system with heat recoveryMax. air ?ow rate: 180 m3/hUp to 92 % heat recoveryPage 14VITOVENT 300-WWall mounted, mechanical ventilation system with heat recovery Max. air ?ow rate: 300/400 m3/hUp to 93 % heat recoveryPage 14Decentralised mechanical ventilation unitVITOVENT 300-FFloorstanding mechanical ventilation system with heat recovery Max. air ?ow rate: 280 m3/hUp to 98 % heat recoveryIn conjunction with heat pump compact appliancesPage 18VITOCAL 161-ADHW heat pump with ventilation function Max. air ?ow rate: 300 m3/h Page 20VITOVENT 300-CCeiling or wall mounted, mechanical ventilation system with heat recovery Max. air ?ow rate: 150 m3/hUp to 89 % heat recoveryPage 16VITOVENT 200-DRegulated, single room ventilation with heat recovery Max. air ?ow rate: 55 m3/hUp to 90 % heat recoveryPage 2212/13Vitovent 300Vitovent 300-WMechanical ventilation systemsViessmann offers the Vitovent 300 and Vitovent 300-W mechanical ventilation systems for a healthy environmentEnclosed spaces need to be ventilated regularly by opening windows. However, ventilation is not particularly reliable in most cases: Excessive ventilation results in the loss of expensive heating energy; too little, and humidity is not removed adequately, making indoor air unpleasant.The Vitovent 300 and Vitovent 300-W mechanical ventilation systems replace the air continuously for a pleasant and healthy ambience, while removing odours and noxious substances.Prevent mould, protect the building fabricOne of the main causes of mould growth is humid indoor air. Mould can harm the health of residents and cause permanent damage to the fabric of the building. Investing in a mechanical ventilation system is cheaper than remedying building damage caused by fungal growth and mould.Allergy sufferers can breathe more easilyThe Vitovent 300 and Vitovent 300-W mechanical ventilation systems allow allergy sufferers to enjoy fresh air too. A ?ltration system, featuring an effective optional pollen ?lter, cleans the supply air of allergens and harmful substances. This signi?cantly reduces the growth and spread of mites and mildew, thereby creating an irritant-free environment.Enjoy peace and securityThanks to continuous air replacement with the Vitovent 300 and Vitovent 300-W, windows only ever need to be opened for cleaning. Not only does this improve security against burglary, it also keeps traffic noise out.Ventilating virtually without energy lossThe Vitovent 300 and Vitovent 300-W ventilation systems are particularly energy efficient. During the colder months of the year, the powerful heat exchanger utilises up to 93 percent of the heat contained in the extract air for heating incoming fresh air. The integral electric preheater coil ensures continuous frost-free operation of the Vitovent 300-W, even at low outside temperatures.Natural coolingAt warmer times of the year, the heat exchanger of the Vitovent 300-W can be bypassed completely via the integral, automatic bypass damper. An optional summer cassette is available for the Vitovent 300. This temperature controlled circuit allows cool outdoor air to enter the interior at night, thereby ensuring a pleasantly fresh environment.Remote controlThe remote control included in the standard delivery allows the ventilation unit to be regulated conveniently from the living space.Remote control for Vitovent 300Remote control for Vitovent 300-WVitovent 300-W1 Bypass damper2 DC fan with impeller vanes bent backwards3 Extract air filter4 Preheater coil5 Countercurrent heat exchanger6 Outdoor air filterVitovent 300Take advantage of these bene?ts ?

Convenient regulation via directly connected remote control unit65421314/15Vitovent 300-CDomestic ventilation systemSpace saving mechanical ventilation system for ceiling or wall mounting with heat recovery for modernisation projectsWith the new Vitovent 300-C mechanical ventilation unit, Viessmann offers a solution that is particularly suitable for the controlled ventilation of apartments. Especially after implementing energy saving measures in a building and insulating exterior walls, the shell of the old building becomes more airtight and requires adequate ventilation to protect the building fabric. Otherwise, there is a risk of mould growth due to excessive humidity in the interior.Fits easily in recessesThe Vitovent 300-C impresses with its compact, slimline design. It can be concealed quite easily in suspended ceilings. For example in a hallway, where the ventilation ducts to the rooms on either side can also be installed.Vertical installation in a wall is equally possible, for example in a storeroom.Ideal for most apartmentsThe unit's maximum air delivery of 150 m3/h is sufficient for ventilating interiors of between 65 and 90 m2 quite comfortably.Heat recovery and summer bypassThe Vitovent 300-C ventilation unit utilises up to 89 percent of the latent heat in extract air, warming the cool outdoor air with the assistance of a cross-countercurrent heat exchanger. This saves energy and reduces heating costs all year round.An automatic bypass circuit for the warmer months of the year is integrated as standard. Fresh, cool supply air can then be routed past the heat exchanger and directly into the interior, thereby achieving a passive cooling effect.Additional sound insulation on request Although this compact appliance already operates very quietly, additional insulation measures can be implemented depending on the intended installation site. Matching system accessories include a silenced compressor for integration into the unit, as well as outdoor and exhaust air silencers.Allergy sufferers can breathe more easilyThe Vitovent 300-C mechanical ventilation system also allows allergy sufferers to breathe more easily. A ?ltration system, featuring an effective pollen ?lter, cleans the supply air of allergens and harmful substances, thereby creating an irritant-free environment.Remote control includedThe standard delivery includes a remote control for convenient regulation of the unit from the living space.Vitovent 300-C1 Bypass2 Radial DC fans3 Cross-countercurrent heat exchanger4 Electric preheater coil5 Condensate drain6 Outdoor air filter7 Sensor and remote control connection, accessible from the outside8 Outdoor air9 Exhaust air10 Extract air filter11 Extract air12 Supply airTake advantage of these bene?ts ?

The heat pumps that can be combined with this ventilation system offer a heating output of between 3.0 and 10.6 kW. The system as a whole can be used for interiors with up to 210 m2.All functions on the smallest of footprintsThe system combination is particularly suitable for new buildings, since all functions, such as ventilation, heating/cooling and domestic hot water heating, can be implemented in the smallest of spaces. The Vitovent 300-F can be installed directly to the right or left of the heat pump, thereby forming a harmonious unit with a small footprint.High operating convenienceThe Vitovent 300-F ventilation module is connected directly to the heat pump. All settings can be made from either the heat pump's Vitotronic 200 control unit, a common remote control unit or the Vitotrol app. At the same time, operation of heat pump and ventilation are matched automatically to each other.Up to 98 percent heat recoveryThe Vitovent 300-F recovers up to 98 percent of the latent heat in extract air, using it to heat the incoming outdoor air.Air tempering in passive housesCombining a Vitovent 300-F and a heat pump is highly appropriate for air tempering in passive houses. By and large it makes a hydraulic distribution system super?uous. A reheater coil with an output of up to 1.5 kW is integrated for this purpose. In addition, an optional heating water buffer cylinder with a capacity of 25 litres is integrated into the Vitovent 300-F.Additional utilisation of solar energyIf the Vitocal 343-G/242-G or Vitocal 242-S heat pump is used, then direct connection of solar collectors is possible for domestic hot water heating. Energy costs can be slashed thanks to the integral solar function for solar DHW heating. Lastly, utilisation of power generated on site by means of a photovoltaic system contributes to further energy savings.Quick installation with ?at duct systemA ?at plastic duct system makes routing in un?nished buildings particularly easy. From air distribution boxes with integral silencers, the supply and extract air valves are connected individually via a ?exible ?at plastic duct. The smooth internal walls of the ?at plastic ducts are anti-bacterial and anti-static.* The Vitovent 300-F can be combined with the following heat pumps: Vitocal 222-S/242-S, 200-A, 222-G/242-G, 333/343-G, 300-A (301.B11 and B14), 200-G, 300-G (301.B06 and B17), 350-G (351.A07) and Vitocaldens 222-F.Take advantage of these bene?ts ?

It is equally suitable for detached houses and smaller commercial premises. Ideal application areas include restaurants, bakeries and spaces that need cooling (e.g. wine cellars or food stores).For either recirculation or extract airThe recirculation air version of the Vitocal 161-A draws in air from the room where it is installed. The heat pump raises the heat contained in the recirculation air to 65 °C for increased DHW hygiene. At the same time, the air is dehumidi?ed, thus protecting the fabric of the building and improving quality of life for all concerned.Heat pump usable as central extractorBy replacing the recirculation air cover with an extract air cover (accessory), the Vitocal 161-A can be made to draw in warm extract air via ducts (to be installed on site) from other rooms in the detached or two-family house, such as the bathroom or kitchen.Economical and efficient DHW heatingThe compact appliance is equipped with all components required for efficient DHW heating. The space efficient casing houses the heat pump module, as well as a 300 l DHW cylinder, plus the control unit.The Vitocal 161-A is available in two versions: one without internal indirect coil for mono mode operation and one with integral indirect coil for use in a dual mode heating system, for example in combination with a solar thermal system.Outstanding designThe Vitocal 161-A has been presented with the "red dot award: product design" for its high grade timeless design.Vitocal 161-A DHW heat pumpLabel for heat pumps with control technology that enables them to be incorporated into a Smart Grid.1 Highly efficient compressor2 Evaporator with large surface area for efficient heat transfer3 Control unit4 300 l DHW cylinder with Ceraprotect enamel coating5 Magnesium anode6 Internal indirect coil (type WWKS)Take advantage of these bene?ts ?

The incoming air is ?ltered and heated via the cross-countercurrent heat exchanger with the heat extracted from the indoor air. Up to 90 percent of the heat in the extract air is recovered. Up to 55 m3 of air is replaced per hour. A comprehensive ventilation concepts can also be realised if several units are employed.The installation of the ventilation unit requires only one opening in the external wall. No additional air ducts need to be installed – only one power supply (230 V) is required. A choice is available between angular and rounded casing designs for high ?exibility plus quick and easy installation.The Vitovent 200-D mechanical ventilation unit is very well suited, for example, to combating problems with damp as part of a modernisation project or conveniently maintaining a comfortable ambience.At the same time, heat recovery saves energy when compared, for example, to essential window ventilation. That reduces heating bills.The supply air function provides additional comfort in summer: At night, the heat exchanger can be bypassed and cool night air fed into the interior.Straightforward operation and maintenanceThe programming unit is integrated into the internal wall cover. Supply and outdoor air ?lters can be replaced and central components cleaned and inspected quite comfortably from the inside.The wireless operating switch (accessory) with no batteries allows convenient changing of the operating mode of one or more appliances simultaneously. Technology based on the piezo-electrical effect means that no cable connection or battery changes are required, so the switch can be positioned without incursion into the building fabric.The quiet, energy efficient fans in the Vitovent 200-D are continuously regulated subject to air quality by means of the optional air quality sensor. In automatic mode, the fan speed is only as high as that required for a healthy and thermally comfortable indoor environment.Round wall sleeve with exterior wall coverSquare wall sleeve with exterior wall cover12341 Outdoor air2 Supply air3 Extract air4 Exhaust airInstallation options for Vitovent 200-DVitovent 200-D1 Exterior wall cover2 Cross-countercurrent heat exchanger3 DC fan (outdoor/supply air)4 Extract air filter5 Casing made from expanded polypropylene (EPP)6 Internal wall cover7 Programming unit (on the right-hand side)Vitovent 200-D – elegant wireless operating switchTake advantage of these bene?ts ?

From central air distribution boxes with integral silencers, the supply and extract air valves are connected individually via the ?at plastic duct. Ducts are ?exible and pliable. Suitable bends are available for sharp angles.The smooth insides of the air distribution ducts have an antibacterial and antistatic effect to prevent bacterial growth and dust deposits.The system is crush-resistant and can be routed under screed, in un?nished concrete or suspended ceilings. The air duct is plugged together quickly and easily. A lip seal on each element makes connections airtight.A metal duct system is available as an alternative.Restrictors regulate the air volumeThe air volume is set individually for each room depending on the room size. The air throughput of the individual ducts is calculated and preset by means of the restrictors at the air distribution boxes. This in turn saves time for precise adjustment of the complete system. Plastic or metal valvesSupply and extract air valves made from metal or plastic are available to match the duct system. The supply air can also be fed into the room via a ?oor outlet with a walk-on stainless steel grate. Insulation against condensationComponents in contact with outside air are ?tted with special insulation to prevent the formation of condensate and thermal bridges in the building envelope.All-round service from ViessmannOn request, Viessmann can provide extensiveservices for engineering Vitovent systems: ?

Only regularly maintained systems ensure a consistently high quality of indoor air: by ?ltering out dust and pollen.Servicing by the operatorViessmann mechanical ventilation systems are designed in such a way that operators can carry out essential service work themselves quite easily. This includes: ? Cleaning and changing of ?lters as often as twice a year ? Resetting the status display for ?lter replacement ? Recognising fault messages on the control unit (such as the need for a ?lter change)No additional accessories are required for this purpose. The service indicators can be controlled conveniently via the ventilation unit remote control.Servicing by a contractorScope and frequency depend ultimately on individual circumstances (e.g. the location). In order to ensure consistent system quality, we recommend having the following steps taken every two years as part of an inspection by a quali?ed contractor: ? Filter changes at air outlets and valves ? Cleaning the heat exchanger ? Visual inspection of all air outlets and valvesStraightforward servicing of the mechanical ventilation system (in this case the Vitovent 300-W): Visual inspection of the ?lters (top left) and ?lter replacement in the case of severe contamination.The heat exchanger can be cleaned by means of a brush, vacuum cleaner or jet spray.26/27Which system for which application?Checklist VITOVENT 300 VITOVENT 300-W Speci?cations and equipmentAir ?ow rate 180 m3/h 300/400 m3/h Living space (approx.) 110 m2 230/370 m2 Dimensions excluding connectors Length (depth) x width x height 310 x 560 x 600 mm 540 x 677 x 843 mm Weight: 25 kg 39 kg Outdoor air ?lter (?lter class to EN 779) Delivered condition/accessory G3/F7 G4/F7 Extract air ?lter (?lter class to EN 779) Delivered condition/accessory G3/G3 G4/G4 $OOHUJ\\?iOWHU?
