4 205 113 / 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

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.

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
