9 / 02 Functonal prncple of the heatng system 4. Functonal prncple of the heatng system Components Ol/Gas heatng boler Functon Burns fuel ol or natural gas safely and envronmentally frendly. Extracts the heat from the generated combuston gases and transfers t to the heatng water. Calorfer It holds a reserve of domestc hot water for consumpton (e.g. for showerng). Boler control unt Radator, floor heatng Controls and montors the operaton of the heatng boler. Mantans the desred room temperature optmally and fuel effcently, ndependently of the outsde temperature. Releases the heat of the heatng water nto the room. Heatng pump Transports the heatng water from the heatng boler to the radators and back to the heatng boler, where t s reheated. Mxng valve Adjusts the heatng flow temperature by admxng colder return water (water flowng to the radator) to mantan the desred room temperature, ndependently of the outsde temperature. Pressure gauge Dsplays the hydraulc pressure n the heatng system. Ar bleeder Elmnates any ar to make sure that the system contans only heatng water. Safety valve Prevents an overpressure n the system. Daphragm expanson tank Mantans the pressure n the system constant. Hot water and hot water ppes Convey the heat generated from the heatng boler to the radators. 9

10 Commssonng / 02 Dependng on the workng prncple of the heatng system selected, there may be extra components or some may not be provded. Have your system explaned n detal by the specalst. Chmney, flue system Radator(s) or underfloor heatng where ftted Mxer valve Heatng pump Water heater Heatng boler The hot water heated by the heatng boler s conveyed to the radators, or s used to heat the domestc hot water n the water heater. 5. Commssonng Commssonng of a newly nstalled system may only be carred out by a qualfed nstaller. A full nstallaton check must be completed pror to start-up. - Set the man SYSTEM swtch to 0 - Open the shut-off valves n the flow and return lnes. - Open the shut-off valve n the gas lne to the boler - Swtch on the man swtch outsde the heatng room (f present). The heatng nstallaton often has an addtonal danger swtch that only sets the gas burner out of operaton. 5.1 Checks pror to start-up Check the water level n the heatng system. The heatng system must be flled wth water and all the ar removed. Observe the regulatons regardng antfreeze and water treatment. Open the shut-off valves n the flow and return lnes. Check the fresh ar supply to the heatng system. Check the settngs for the operatng modes. 5.2 Swtchng on the system Gas tap open. Swtch on the man swtch.

11 / 02 Boler system control U 3.1 and U Boler system control U 3.1 and U What s the functon of the heatng controller TopTronc T? The boler controller s, n conjuncton wth the temperature sensor connected to t, so to speak, the bran of the heatng system. Its man functons are: - mantanng the desred room temperature ndependently of the outdoor temperature - heatng the lvng space when requred - produce warm water (e.g. for showerng) only when requred - dsplayng nformaton Further functons: - Input of desred temperatures and operatng modes - Turn the burner ON/OFF - Temperature montor The correct settngs for the heatng system have already been appled by Hoval, or the nstaller, durng commssonng. Any changes to those settngs should only be carred out f you go away on a trp or f your home s to cold or too warm. An overvew of the most frequent questons/answers can be found on page 13, 18 of these nstructons. ENERGY 6.2 How you can save energy For your beneft and for the envronment Usng energy more effcently by avodng unnecessary losses: Wth lttle effort you can optmze the operaton of your system and make t worth whle. - You can save money. Enough money to pay your ol or gas bll every sxth year - Every year, you can save the energy equvalent of a bathtub full or heatng ol In autumn, t s worth whle turnng the heatng off agan on warm days Ths prevents the heatng system from producng unnecessary heat n the mornng, due to low outdoor temperatures, and overheatng the house. Turnng the heatng on or off dependng on the weather condtons s one of the most effectve energy savng measures. If you want to save yourself gong down the basement, you may want to consder acqurng a remote control from Hoval, whch wll allow you to operate and control the heatng comfortably from your lvng room. 6.3 Basc dsplay The basc dsplay shows the day of the week, date and tme of the day, as well as the current boler temperature and room temperature (room staton). 11

It s only to be swtched back on after a watng tme of approx. 2 hours. The ol suppler s to supervse the fllng of the heatng ol tank. 8.2 Fuel Ol burners generally operate wth 35 sec fuel ol. The heatng boler s also sutable for gas frng f ftted wth the approprate burner. 8.3 Burner settng Your burner was checked at the factory. Settng s carred out by the heatng nstaller or Hoval after-sales servce at the tme of commssonng (for output settngs, see Data of your heatng nstallaton. pages 5/6). 8.4 Heatng space and fresh ar supply For correct combuston of the heatng ol the burner requres a supply of fresh ar. Provson s therefore always to be made for an adequate supply of fresh ar to the boler house for both combuston and ventlaton. Contamnated ntake ar, e.g. wth dust or textle fbres leads to a rapd deteroraton of the combuston and possble reducton n the lfe of the boler. So the bolerhouse s to be kept as clean and as free of dust as possble. No chemcals are to be stored n the bolerhouse or the n the zone of the fresh ar supply to the bolerhouse. 8.5 Placng n operaton When frst placng n operaton, take note of the Techncal nformaton / nstallaton nstructons for the burner. Check the water content of the heatng system. Check the ol level n the ol tank wth the dpstck. Check the settngs of the boler automatc system, and thermostats. Check the ol supply to the burner (open the ol ppelne gate valve). Check the fuses on the swtch panel. Place the emergency swtch to the poston On. The burner can now be placed n operaton by swtchng on the man swtch and the operatng mode selecton swtch at the heatng boler. 8.6 Placng out of operaton To place the ol burner out of operaton for a short tme t s suffcent to smply swtch off at the operatng mode selecton swtch. For longer perods t s recommended to close the ol shutoff valves. 46

Any operatng faults are sgnalled by the lghtng of a fault clearng button 1 at the ol frng automatc devce and the fault dsplay lamp on the boler. The burner can be restarted by pressng the fault clearng button on the ol burner (max. 2-3 tmes). If burner operaton s not possble n spte of ths, notfy the specalst Burner mantenance An mportant precondton for cost-effectve operaton and for mantanng good ar qualty s the sound condton of your burner system. The burner must be nspected resp. cleaned by a specalst once a year. We recommend you to conclude a mantenance contract. 47
