Setting the maximum output

Note
You can limit the maximum output for heating operation. The limit is set via the
modulation range. The max. adjustable heating output is limited upwards by the
boiler coding card.
1. Start the boiler.
2. Press K and F simultaneously
until a value flashes (e.g. "85") and
"A" appears. In the delivered con-
dition, this value represents 100 %
of rated output.
On weather-compensated control
units, the display additionally
shows "Max. output".
3. With a/b select the required
value in % of rated output as maxi-
mum output.
