Test function and combustion analysis
The boiler has two pressure taps to measure the combustion gas
temperature, the combustive air and the concentrations of O

on the outside of the fl ue gas header.
To access these pressure taps, unscrew the screw which holds the
blanking cover and its seal together.

Maximum gas fl ow combustion analysis
Activate the test function at the maximum heating power, pushing
for 5 seconds the RESET until the yellow led 9 blinks (also 60°C led is
lit to indicate that Chimney is at max. CH absolute) The rotate the CH
knob to the min., intermediate position or max position it’s possible
to switch between min, max CH absolute and max DHW power
(respectively the 40°C, 60°C and 80°C are lit to indicate the power
level.
The function is automatically deactivated after 10 minutes or by
pressing the RESET button.
