values
Should the CO
2
values read differ from those in the table, modify
“PAR 73”
as follows:
– keep the flue gas analyser inserted in the take-off point on
the outlet ducts
– go into the parameter section by pressing the buttons
r
and
t
(for approximately 5 seconds) at the same time until
"PAR
01"
(parameter number) and the value set (0) appears on the
display
– press and hold the
t
button and scroll through the param-
eters until you reach
“PAR 15”
(maximum heating output)
during the winter season, or parameter
“PAR 20”
(maximum
DHW output) during the summer season
– press and hold the
<
button to change the value to
“0”
(force
minimum power)
– exit the parameter section by pressing and holding down the
buttons
r
and
