3.1.2 Boiler display
aquaPLUS boilers have an advanced multifunction boiler
display. When the main ON/OFF control is in the "ON"
position the display will normally show the temperature
of water in the boiler circuit (50° C in the example),
which confirms that the boiler is functioning correctly.
The display supplies the following information:
1 Fan speed malfunction
2 Heating demand
3 Hot-water demand
4 Warm-start on (Comfort mode)
5 Pump on
6 Gas valve on
7 Actual Heating-system flow temperature (e.g. 50 °C)
or
Displaying of a status/error code
8 Correct burner operation (normal flame) or
lock out (crossed-out flame)
