Only the frost protection function for the cylinder remains active. 4.16 Guaranteeing the correct filling pressure of the heating system 4.16.1 Checking the filling pressure of the heating installation Note To ensure that the heating installation operates smoothly, the filling pressure when the heating installation is cold must be between 0.1 MPa and 0.2 MPa (1.0 bar and 2.0 bar) or lie between the two dashed lines in the bar graph display. If the heating installation extends over several storeys, a higher filling pressure may be required for the heating installation. Ask a competent person for details. In addition, the symbol appears after approx. one minute. If the filling pressure in the heating installation falls below 0.05 MPa (0.5 bar), then the product switches off. The display alternates between the fault message F.22 and the current filling pressure. 1. Press twice. The values for the current filling pressure and for the minimum and maximum filling pressures appear in the display. 2. Check the filling pressure in the display. 1/2 System pressure: 0.1 ... 0.2 MPa (1.0 ... 2.0 bar) The filling pressure is in the intended pressure range. 2/2 Filling pressure: < 0.08 MPa (< 0.80 bar) Fill the heating installation. ( Page 10) If you have topped up the installation with suf- ficient heating water, the display automatically disappears after 20 seconds. 4.16.2 Filling the heating installation Caution. Risk of material damage due to heating water that is extremely calciferous or corrosive or contaminated by chemicals. Unsuitable tap water damages the seals and diaphragms, blocks components in the product and heating installation through which the water flows and causes noise. Only fill the heating installation with suit- able heating water. 1. Ask a competent person where the filling cock is located. 2. Connect the filling tap to a heating water supply in the way you were told by the competent person. 3. Open all radiator valves (thermostatic radiator valves) of the heating installation. 4. Open the heating water supply. 10 Operating instructions ecoTEC plus 0020245033_02 Troubleshooting 5 5. Turn the filling cock on slowly and allow water to flow in until the required filling pressure has been reached. 6. Close the heating water supply. 7. Purge all radiators. 8. Check the filling pressure in the display. 9. Top up with more water if necessary. 10. Close the filling cock. 11. Return to the basic display. ( Page 8) 4.17 Protecting the heating installation against frost 4.17.1 Frost protection function Caution. Risk of material damage due to frost. The frost protection function cannot guarantee flow through the entire heating installation, which means that parts of the heating installation may freeze and therefore become damaged. During a period of frost, ensure that the heating installation remains in operation and that all rooms are sufficiently heated, even when you are away. Note To keep the frost protection devices active, you should switch your product on and off using the controller, if one is provided. 5.2 Calling up (Live monitor) status codes Press and at the same time. Status codes Overview ( Page 13) The current operating status (status code) is shown on the display. 6 Care and maintenance 6.1 Maintenance An annual inspection of the product carried out by a competent person is a prerequisite for ensuring that the product is permanently ready and safe for operation, reliable, and has a long working life. After servicing, complete the relevant service interval record section of the benchmark checklist, located at the rear of the installation manual. 6.2 Caring for the product Caution. Risk of material damage caused by unsuitable cleaning agents. Do not use sprays, scouring agents, de- tergents, solvents or cleaning agents that contain chlorine. Clean the casing with a damp cloth and a little solvent- free soap. If the heating flow temperature falls below 5 °C when the on/off button is on, the product comes into operation and heats the circulating water to approx. 30 °C on both the heating side and the hot water side (if available). 4.17.2 Draining the heating installation You can guarantee frost protection during very long switchoff times by draining the heating installation and the product completely. Consult a competent person about this. 5 Troubleshooting 5.1 Detecting and rectifying faults If faults occur, proceed in accordance with the table in the appendix. Troubleshooting ( Page 14) If you have been unable to eliminate the fault using the measures specified, or fault messages (F.xx) appear, consult a competent person. 6.3 Reading maintenance messages If the symbol is shown on the display, the product requires maintenance work. The product is not in fault mode but continues to operate. Consult a competent person about this. If the water pressure is flashing at the same time, simply add more heating water. 6.4 Checking the condensate drain pipework and tundish The condensate drain pipework and tundish must always be penetrable. Regularly check the condensate drain pipework and tun- dish for faults and, particularly, for blockages. You must not be able to see or feel any obstructions in the condensate drain pipework and tundish. If you notice a fault, have it rectified by a competent per- son. 0020245033_02 ecoTEC plus Operating instructions 11 7 Decommissioning 7 Decommissioning 9 Guarantee and customer service 7.1 Temporarily decommissioning the product Caution. Risk of material damage due to frost. The frost protection and monitoring devices are only active while the unit is connected to the power mains and switched on via the on/off button, and when the gas isolator cock is open. Temporarily decommission the product only if no frost is expected. Temporarily decommission the product only if no frost is expected. Press the on/off button. The display goes out. When decommissioning the product for a prolonged period (e.g. holiday), close the gas isolator cock and also, for combination products, the cold water stop valve. 7.2 Permanently decommissioning the product Have a competent person permanently decommission the product. 8 Recycling and disposal The competent person who installed your product is re- sponsible for the disposal of the packaging. 9.1 Guarantee Two year guarantee for ecoTEC plus appliances Vaillant provides this appliance with a parts and labour guarantee against defects that may occur within twentyfour months of the installation date.

No hot water The power supply in the building is disconnected. Heating remains cold The product is switched off. The heating flow temperature is set too low or to the Heating off position, and/or the hot water temperature is set too low. The system pressure is insufficient. Low water pressure in the heating installation (fault message: F.22). There is air in the heating installation. After three unsuccessful attempts to ignite the flame, the product switches to fault mode (fault message: F.28). Hot water generation functioning correctly; heating does not start up. The external controller is not set correctly. Measure Open both gas isolator cocks. Check the fuse in the building. The product switches on automatically when the power is restored. Switch on the product ( "Switching on the product" section). Set the heating flow temperature and hot water temperature ( "Setting the heating flow temperature" section/ "Setting the hot water temperature" section). Fill the heating installation ( "Filling the heating installation" section). Have your competent person purge the heating installation. Press the fault clearance key for one second. The product makes another attempt to ignite the flame. If you have been unable to eliminate the ignition fault after three fault clearance attempts, consult a competent person.
