Press or to activate or deactivate Green iQmode respectively.◁ Mode on or Mode off will flash on the display.4. Confirm by pressing .◁ If you have activated Green iQ mode, the symbolwill appear on the basic display. If you have deactiv-ated Green iQ mode, the symbol will disappearfrom the basic display.4.14 Guaranteeing the correct filling pressure ofthe heating installation4.14.1 Checking the filling pressure of the heatinginstallationNoteTo ensure that the heating installation operatessmoothly, the filling pressure when the heatinginstallation is cold must be between 0.1 MPa and0.2 MPa (1.0 bar and 2.0 bar) or lie between thetwo dashed lines in the bar graph display.If the heating installation extends over severalstoreys, a higher filling pressure may be requiredfor the heating installation. Ask a competent per-son for details.In addition, the symbol appears after approx.one minute.If the filling pressure in the heating installationfalls below 0.05 MPa (0.5 bar), then the productswitches off. The display alternates between thefault message F.22 and the current filling pres-sure.1. Press twice.◁ The values for the current filling pressure and for theminimum and maximum filling pressures appear inthe display.2. Check the filling pressure in the display.1 / 2System pressure: 0.1 … 0.2 MPa (1.0 … 2.0 bar)The filling pressure is in the intended pressure range.2 / 2Filling pressure: < 0.08 MPa (< 0.80 bar)▶ Fill the heating installation. (→ Page 9)◁ If you have topped up the installation with suf-ficient heating water, the display automaticallydisappears after 20 seconds.4.14.2 Filling the heating installationCaution.Risk of material damage due to heatingwater that is extremely calciferous or cor-rosive or contaminated by chemicals.Unsuitable tap water damages the sealsand diaphragms, blocks components in theproduct and heating installation throughwhich the water flows and causes noise.▶ Only fill the heating installation with suit-able heating water.▶ In case of doubt, ask a competent personfor details.1. Ask a competent person where the filling cock is loc-ated.2. Open all radiator valves (thermostatic radiator valves) ofthe heating installation.Conditions: Product for heating mode only▶ Connect the filling cock to a hot water supply in the wayyou were told by the competent person.▶ Open the hot water supply.▶ Turn the filling cock on slowly and allow water to flow inuntil the required filling pressure has been reached.▶ Close the hot water supply.▶ Purge all radiators.▶ Check the filling pressure in the display.▶ Top up with more water if necessary.▶ Close the hot water supply.Conditions: Product with integrated hot water generation and filling loopAB1432▶ Fit the double non-return valve (1) of the filling line tothe cold water stop valve and secure the valve with thespring clip (2).▶ To fill, first open the stop valve (3).▶ Slowly open the stop valve (4) so that the water flowsinto the heating system. Fill it with water until the re-quired filling pressure is reached.▶ Close the stop valve (4).▶ Purge all radiators.▶ Check the filling pressure in the display.▶ Top up with more water if necessary.▶ After filling, close both stop valves and disconnect thefilling device by removing the double non-return valvefrom the cold water stop valve.
