power supply to the boiler;

use rotational switch (3);
• Check the pump operation: make
sure that the direction of the rotation
is correct;
• Remove any air from the pump by
removing the end cap of the pump
motor housing.
It’s recommended to keep the boiler at
50% load for a while after the first
startup, as this is the easiest base for
starting the combustion analysis. This
can be assured as follows:
• Open the lid of the boiler controller;
• Use rotational switch (3) for going to
parameter P9
in the menu;
• Change P9 (5) into 50% (push pro-
gramming button (4), change value
with rotational switch (3), push pro-
gramming button (4) to confirm);
• Close the lid of the boiler controller.
