Notes on the documentation 1 Notes on the documentation The following instructions are intended to guide you throughout the entire documentation. Other documents apply in addition to these operating instructions. We accept no liability for any damage caused by failure to observe these manuals. 1.
1 Notes on the documentation i 4 Vaillant Ltd. supports the Benchmark Initiative. A benchmark check-list for commissioning gasfired boilers is attached to these installation instructions. It is very important that this document be filled out properly when installing, commissioning and handing-over to the system operator.
a Safety 2 2 Safety 2.1 2.2 Safety and warning information > When operating your boiler, take account of the general safety instructions and the warning notes that appear before each action. 2.1.
a a 2 Safety 2.3 Basic safety instructions > Observe the following safety instructions at all times. Installation and settings The boiler must only be installed by a suitably qualified competent person. The existing regulations, rules and guidelines must be observed when doing so. He is also responsible for inspection, maintenance and repairs to the boiler, and alterations to the gas volume setting.
a Safety 2 Caution! > Under no circumstances should you add frost protection agents (or other additives, e.g. jointing compounds, corrosion protection agents, etc.) to the heating water without first consulting your qualified competent person. Otherwise, this could result in damage to seals and diaphragms as well as noises during heating operation. Vaillant assumes no liability for this or any consequential damage. Another way to protect the heating system and the boiler from frost is to drain them.
3 Description of devices and functions 3 3.1 Description of devices and functions 3.2 Function Your Vaillant ecoTEC plus is a gas-fired wall hung high efficiency boiler, which generates heat for heating and/or hot water production. VU boilers can be operated together with a domestic hot water cylinder, which stores a larger volume of hot water. VUI boilers are fitted with internal hot water production and a domestic hot water cylinder to achieve increased hot water convenience. Design 3.2.
Description of devices and functions 3 3.2.4 Hot water production with VUI boiler The hot water production with additional stratified cylinder functions in the same way as on the VUW boiler (¬ Section 3.2.3). In addition, you can activate the heating of the stratified cylinder by switching on Comfort mode. This uses special charging technology to ensure that you have a similar hot water convenience as you would get with a much bigger conventional domestic hot water cylinder.

You must always confirm a change to a value. Only then is the new setting saved.
Operation 5 5 Operation 5.1 Putting the boiler into service. 5.1.1 Opening/closing the isolator devices The isolator devices are open if the slot for the screwdriver is parallel to the pipes. > Open the gas isolator cock (3. > Check that the heating flow (4) and heating return (1) isolator devices are open. Open these if they are closed. For the unit version VUW and VUI: > Also open the cold water stop valve (2).
5 Operation If the boiler is switched on, the current heating flow temperature and other information will appear in the display (2) (¬ Fig. 4.5). You can see the filling pressure in the right-hand bar graph display or display the exact value using the selection buttons to the right of the display. To set your boiler to suit your needs, read ¬ Section 5.2 to Section 5.4 which describe the setting options for hot water production and the heating mode. Water pressure 1,0 3 5.1.
Operation 5 Proceed as follows to fill the heating system: > Open all radiator valves (thermostatic radiator valves) of the heating system. > Connect the filling cock for the heating system, as explained by your approved competent person, to a cold water draw-off valve. > Open the filling cock slowly. > Fill it with water using the draw-off valve until the required filling pressure is reached in the display. > Close the draw-off valve. > Bleed all the radiators.

Setting the hot water temperature DHW temperature 45 or the plus button > Use the minus button to activate or deactivate the comfort mode. > Confirm the change by pressing the right-hand selection ("OK"). button 5.6 Setting the hot water temperature When you have activated Comfort mode, the symbol " " is shown in the basic display.
Operation 5 a Danger! Risk of scalding. VUI 937 only: The boilers are equipped with an automatic Legionella protection function: If the temperature in the hot water domestic hot water cylinder falls below 50 °C, the cylinder is heated up to 70 °C once every 24 hours. > If this is the case, try not to draw off any water. Your approved competent person can switch off the Legionella protection function. Ask your approved competent person for details about this. 5.
5 Operation > Ask your approved competent person whether an eBUS auto controller is connected. If you are using an eBUS auto controller: > Set the hot water temperature on the boiler to the maximum possible temperature. > Set the desired hot water temperature (hot water target temperature) on your controller.

Operation 5 > Use the plus button to set your required heating flow temperature. > Confirm the change by pressing the right-hand selection ("OK"). button 5.7 Temporarily shutting down the boiler b Caution! Risk of damage caused by frost. Anti-freeze and monitoring devices are only active while the boiler is connected up to the power mains and the on/off switch is on. > Do not isolate the boiler from the power mains. > Leave your boiler switched on at the on/ off switch.
6 Energy saving tips 6 Energy saving tips Fitting a weather compensator Weather compensators regulate the heating supply temperature according to the outside temperature. Thus it is ensured that heat in excess of what is required at that moment is not generated. In addition, desired heating and set-back phases (e. g. at night) are automatically turned on and off by using integrated time programmes.
Energy saving tips 6 Energy-conscious use of water Energy-conscious use of water can reduce your bills considerably. For example, taking a shower instead of a bath: whereas about 150 litres of water are required for a bath, a modern shower equipped with water-saving fittings only requires a third of this water quantity. By the way: A dripping water tap wastes up to 2000 litres of water and a leaking toilet flush wastes up to 4000 litres of water each year.
7 Troubleshooting 7 Troubleshooting a 7.1 Danger! Risk of injury and material damage due to incorrect maintenance and repairs. If maintenance is not carried out, or carried out incorrectly, this may adversely affect the operational reliability of your boiler. > Never perform maintenance or repairs on your boiler by yourself. > You must employ an approved competent person or Vaillant Service Solutions (0870 6060 777) to complete such work. Reading fault messages F.75 Fault Pump water shortage 7.
Troubleshooting 7 7.2 Detecting and rectifying malfunctions If problems occur whilst operating your boiler, you can carry out the following self-checks: Problem No hot water, heating stays cold; Boiler does not start DHW mode without any problems; Heating does not start: Possible cause Solution Building gas isolator cock closed > Open building gas isolator cock (¬ Section 5.1.
7 Troubleshooting In addition, the maintenance symbol (open-ended spanner) is displayed after approx. one minute. If the filling pressure falls below 0.05 MPa (0.5 bar), the boiler switches off and the fault message F.22 appears in the display. To put the boiler into operation again, you must fill the heating system with water (¬ Section 5.1.3 and 5.1.4). The boiler will only ignite automatically again once you have reset it manually.

12 Glossary 12 Glossary Air/flue gas duct The air/flue gas duct consists of all components that route combustion air to the boiler or exhaust gas from the boiler. Hot water production in VUW boilers In the VUW boiler, the water is heated directly in the through-flow principle. Comfort mode immediately supplies you with hot water at the required temperature, without you having to wait for the water to heat up. In order to do this, the hot water heat exchanger is kept at a preselected temperature level.
