Compute characteristic
points P2 to P8 from
values for P1 and P9
Setup mode
Gas firing, electronic
modulation
Set ignition point P0
max. P0 ≤ P1 + 25.5
°
Prompt for burner start so that points
P2 - P8 can be set.
Contact GWmax. closed to start the
burner: temperature controller must
be closed.
Points P2 to P8 are interpolated
between P1 and P9.
