Energy saving tips20 Operating instructions ecoTEC plus 0020116701_0066 Energy saving tipsFitting a weather compensatorWeather compensators regulate the heating supply temper-ature according to the outside temperature. Thus it isensured that heat in excess of what is required at thatmoment is not generated. In addition, desired heating andset-back phases (e. g. at night) are automatically turned onand off by using integrated time programmes.Weather compensators combined with thermostatic radia-tor valves are the most economical form of heating regula-tion.Operating the heating system in energy-savingmode> Reducing the room temperature at night and in yourabsence.The simplest and most reliable way is to be able to reducethe room temperature using the controller with individuallyselectable timer programmes.> At such times, set the room temperature approx. 5 °Clower than during full heating times.If the room temperature falls by more than 5 °C, you arenot saving any additional energy because increased heatingcapacity would then be required for the next full heatingperiod. Only for longer absences, e.g. during holidays, is itworthwhile to further lower the temperatures.Caution.> In winter, make sure that adequate frost protection ismaintained (¬ Section 5.8).Room temperature> Set the room temperature only as high as would beenough for your comfort level.Each extra degree would cause an increased energy con-sumption of about 6 %.> Adjust the room temperature according to the purposeof use of the room.For example, normally, bedrooms or rooms that are seldomused are heated to 20 °C.Uniform heating> Heat all of the rooms in your dwelling to the same leveland according to their use.If you only heat one room or individual rooms in your dwell-ing, the adjacent unheated rooms will also be heatedthrough walls, doors, windows, roofs and floors and thisheating will be unregulated. The capacity of the radiatorsfor the heated rooms is insufficient for this type of opera-tion. The heated rooms are then not heated sufficiently (thesame effect is caused if doors between heated andunheated rooms (or rooms that are heated to a limiteddegree) are left open).Thermostatic radiator valves and weather compen-sators or room thermostatsThermostatic valves on all radiators maintain the room tem-perature exactly once it is set. You can adjust the roomtemperature to suit your individual requirements andensure effective operation of your heating system usingthermostatic valves in combination with a room thermostator a weather compensator.This is how a thermostatic valve works: If the room temper-ature rises above the value set on the sensor head, thethermostatic radiator valve shuts off automatically andwhen the temperature drops below the defined value, itopens again.Do not obstruct the controller> Do not obstruct your controller with furniture, curtainsor other objects.The controller must be able to record the circulating roomair unhindered. Covered thermostatic radiator valves can beequipped with remote sensors and thus still work.Ventilating living rooms> During the heating period, open windows only for venti-lation and not for temperature regulation.A brief ventilation boost is more effective and energy-sav-ing than windows that are kept open for a long time.Close all the thermostatic valves in the room during ventila-tion.> If you have a room thermostat, set it to the minimumtemperature.This guarantees adequate exchange of air without unneces-sary loss of energy and cooling off.Setting the operating mode> In warmer seasons, when the dwelling needs no heating,turn the heating to summer mode.The heating mode is then switched off. The boiler and sys-tem remain ready for operation for the hot water produc-tion.Setting the hot water temperature> Only heat the warm water up to the extent that is neces-sary for use.Any further heating results in unnecessary power consump-tion and hot water temperatures of more than 60 °C alsolead to increased limescale reduction.Switching on comfort mode (only VUW):Comfort mode immediately supplies you with hot water atthe required temperature, without you having to wait forthe water to heat up. For this, the hot water heat exchangeris kept at a preselected temperature level.If you do not need hot water for a long period, it is recom-mended to turn off comfort mode to save energy further.
