Then the cursor moves according to the boiler current status. Small ventilator symbol represents 0 – 33 %
ventilator output, the middle-sized ventilator symbol represents 33 - 66 % ventilator output
and big ventilator symbol 66 - 100 % ventilator output. On the left –hand side part of display the cursor is
displayed in case of demand on heating
, besides the boiler minimum temperature when making fire
and in boiler fixed run. The cursor flickers during the warm water heating.
In case of the manual regime –the ventilator run (pressing the blue key) the QAA 88 device display will flicker.
It does not regard any fault. The value „0“ is in P 15 parameter. The ventilator run in manual regime will be
terminated by pressing the blue key again and the display stops flickering.
