Press 2. Press ◁ ( ( 4.12 Guaranteeing the correct filling pressure of the heating system 4.12.1 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 0.10 MPa and 0.20 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. ). ). Comf. on or Comf. off are shown flashing in the display. 3. Activate or deactivate Comfort mode by pressing or . 4. Press to confirm this change. ◁ When you have activated Comfort mode, the symbol appears in the basic display. When you have deactivated Comfort mode, the " " symbol goes out in the basic display. 4.11 Switching off the product's functions 4.11.1 Switching off heating mode (Summer mode) 1. To switch off heating mode without switching off the hot water generation, press ( ). ◁ The value of the heating flow temperature appears in the display. 2. Use the button to set the heating flow temperature to Off. 3. Confirm by pressing . ◁ ◁ Heating mode is switched off. The symbol appears in the display. 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: 0.10 … 0.20 MPa (1.00 … 2.00 bar) The filling pressure is in the intended pressure range. 2/2 Filling pressure: < 0.08 MPa (< 0.80 bar) 12 Operating instructions ecoFIT sustain 0020230530_01 Operation 4 ▶ Fill the heating installation. (→ Page 13) ◁ If you have topped up the installation with sufficient heating water, the display automatically disappears after 20 seconds. 4.13 Protecting the heating installation against frost 4.13.1 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. 4.12.2 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 suitable 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. 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 10) 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. 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). 4.13.2 Draining the heating installation When the unit is switched off for an extended period, frost protection can be guaranteed by completely draining the heating installation and the product. ▶ Consult a competent person about this. 0020230530_01 ecoFIT sustain Operating instructions 13 5 Troubleshooting 4.14 Switching the product to standby mode ▶ 6.2 ◁ ◁ ◁ The display shows OFF and goes out.
