Children should be supervised.Ensure that children do not playwith the unit.DangerIncorrectly executed work on theheating system can lead to lifethreateningaccidents.■ Work on gas appliances mustonly be carried out by a registeredgas fitter.■ Work on electrical equipmentmust only be carried out by aqualified electrician.If you smell gasDangerEscaping gas can lead to explosionswhich may result in seriousinjury.■ Do not smoke. Prevent nakedflames and sparks. Neverswitch lights or electrical appliancesON or OFF.■ Close the gas shut-off valve.■ Open windows and doors.■ Remove all people from thedanger zone.■ Notify your gas or electricitysupplier and your heating contractorfrom outside the building.■ Shut off the electricity supply tothe building from a safe place(outside the building).5592 617 GB2

Safety instructionsFor your safety (cont.)If you smell flue gasDangerFlue gas can lead to life-threateningpoisoning.■ Shut down the heating system.■ Ventilate the boiler room.■ Close all doors in the livingspace.In case of fireDangerFire creates the risk of burningand explosions.■ Shut down the heating system.■ Close the shut-off valves of thefuel lines.■ Use a tested fire extinguisher,class ABC.Ancillary components, spare andwearing partsPlease note! Components that are not testedwith the heating system may leadto damage to the heating system,or may affect their various functions.Installation or replacement workmust only be carried out by qualifiedpersonnel.Boiler room requirements5592 617 GB!Please noteIncorrect ambient conditions canlead to damage to the heatingsystem and put the safe operationat risk.■ Ensure ambient temperaturesabove 0 ºC and below 35 ºC.■ Prevent air contamination byhalogenated hydrocarbons(e.g. as contained in paints,solvents or cleaning fluids) andexcessive dust (e.g. throughgrinding/polishing work).■ Avoid continuously high humiditylevels (e.g. through frequentdrying of washing).■ Never close existing ventilationapertures.3

Introductory informationCommissioningThe commissioning and matching of thecontrol unit to local conditions and thestructural characteristics of the buildingmust be carried out by your heating contractor.As the user of new combustion equipment,you may be obliged to notify yourlocal flue gas inspector of the installation[check local regulations]. Your local fluegas inspector will also inform you [whereappropriate] about work he may berequired to perform on your combustionequipment (e.g. regular checks, cleaning).Your system is preset at the factoryThe control unit has been preset at thefactory to "Heating & DHW", i.e. the systemdelivers central heating and DHWheating (if a DHW cylinder is installed).Your heating system is therefore readyfor use:■ Between 06:00 and 22.00 h the systemdelivers central heating withstandard room temperature.■ Between 05:30 and 22:00 h the DHWis boosted to the selected set temperature(if a DHW cylinder is installed).The DHW circulation pump is switchedON (if connected to the control unit).■ Between 22:00 and 06:00 h the systemdelivers central heating withreduced room temperature (set to3 ºC, frost protection).■ Between 22:00 and 05:30 h the DHWcylinder will not be boosted.■ The system automatically changesover between summer and wintertime.Day and time are entered by your heatingcontractor during commissioning.You may change the standard settingspreset at the factory in accordance withpersonal requirements.NoteAll data will be retained in case of powerfailure.5592 617 GB6

For this, we strongly advise you to arrange an inspectionand maintenance contract with your local heating contractor.55

MaintenanceInspection and maintenance (cont.)BoilerIncreasing boiler contamination raisesthe flue gas temperature and therebyincreases energy losses. All boilersshould therefore be cleaned annually.DHW cylinder (if installed)Drinking water filter (where installed)For hygiene reasons:■ Replace filter insert on non-backwashing filters every six months (visualinspection every two months)■ On back washing filters, back washevery two months.Standards DIN 1988-8 and EN 806 specifythat maintenance and cleaning shouldbe carried out no later than two yearsafter commissioning and thereafter asrequired.Only a qualified heating contractorshould clean the inside of a DHW cylinderand the DHW connections.Refill any water treatment equipment(e.g. a lock or injection equipment) ingood time, if such equipment is installedin the cold water supply of the DHW cylinder.In this connection, observe themanufacturer's instructions.In addition for Vitocell 100:We recommend that the correct functionof the sacrificial anode is checked annuallyby your heating contractor. Theanode function can be checked withoutinterrupting the system operation. Theheating contractor will check the earthcurrent with an anode tester.Safety valve (DHW cylinder)Check the safety valve function every sixmonths by venting, or have it checked byyour heating contractor. The valve seatmay become contaminated (see thevalve manufacturer's instructions).5592 617 GB56

Energy saving tipsEnergy saving tipsWith the following steps, you can save additional energy:ABEDC■ Correct ventilation/airing.Briefly open windows A fully and atthe same time close thermostatic radiatorvalves B.■ Never overheat the living space.Endeavour to achieve a room temperatureof 20 °C; every degree of roomtemperature reduction saves up to 6%of your heating bills.■ Close roller shutters (where installed)at dusk.■ Set thermostatic valves B correctly.■ Never cover radiators C or thermostaticvalves B.■ Make full use of the setting optionsoffered by control unit D, e.g. "Standardroom temperature" alternating with"Reduced room temperature".■ Set the DHW temperature of DHW cylinderE at control unit D.■ Only activate the DHW circulationpump (via switching times at the controlunit), when DHW is actually drawn.■ Controlled DHW consumption: Ashower generally uses less energythan a full bath.5592 617 GB57
