Saving energy 60020135485_00 VRT 350 Operating instructions 276 Saving energy6.1 Controlling the room temperatureIt is normally not necessary to heat bedrooms or seldom-used rooms to 20°C.▶ Adjust the room temperature according to the purposeof use of the room.▶ Set the room temperature only as high as would beenough for your comfort level.NoteAn extra degree would mean increased energyconsumption of about 6%.6.2 Reducing the room temperatureYou can reduce the temperature most simply and reliablyby using controllers with individually selectable time pro-grammes.If you reduce the room temperature by more than 5 °C, youdo not save any additional energy, because increased heat-ing capacities would then be required for the next full heat-ing period. Only for longer absences, e.g. during holidays, isit worthwhile to lower the temperatures further.▶ Reduce the room temperature at night and in your ab-sence.▶ During the set-back times, set the room temperature to alower temperature than during full heating times.▶ During a longer absence, set the temperature using the«Days away from home scheduling» function.6.3 Uniform heatingIf you are only heating one room or individual rooms inyour dwelling, the unheated adjoining rooms are alsoheated in an unregulated manner through walls, doors,windows, roofs and floors. The capacity of the radiatorsin the heated rooms is obviously not enough for such anoperating mode. It is then not possible to heat up theheated rooms sufficiently (the same effect arises whendoors between heated and unheated/barely heated roomsare left open).▶ Heat all rooms in your dwelling evenly and according totheir use.6.4 Using thermostatic radiator valves andweather compensators or room thermo-statsThermostatic valves on all radiators maintain the roomtemperature exactly once they have been set. If the roomtemperature rises above the value set on the sensor head,the thermostatic radiator valve shuts off automatically;when the temperature drops below the defined value, itopens again.Exception: The thermostatic valves on the radiators in theroom in which the controller is fitted must be turned fullyon. The radiators are then controlled by the controller andthus maintain the set room temperature.▶ Adjust the room temperature to your individual require-ments using thermostatic radiator valves. You can usethermostatic radiator valves or a room thermostat toensure the economical operation of your heating install-ation.6.5 Do not cover controllersThe controller must be able to detect the circulating airunhindered. Covered thermostatic radiator valves can beequipped with remote sensors and thus still work.▶ Do not cover your controllers with furniture, curtains orsimilar objects.6.6 Ensuring economic hot water generation▶ Set the desired «Hot water circuit» temperature of yourdomestic hot water cylinder only to the temperature youactually need, and under no circumstances higher than60 °C.▶ You should also use the «Timer programs» function forhot water generation in «Automatic mode» or «Summermode». Set the time period so that the water is broughtto the desired «Hot water circuit» temperature shortlybefore it is needed, e.g. in the morning after getting upand in the evening after you return home.▶ If you do not need any hot water for a longer period oftime, switch hot water generation off.▶ If you need hot water rarely or outside the set time peri-ods, use the function «Cylinder boost». |
