C.h. circuit temperature

The output temperature of c.h. water is adjustable
from a minimum of about 38°C to a maximum of
about 85°C (Fig. 2.6), by turning the function se-
lector (8).
Adjustment of c.h. output on the boiler is auto-
matic. The greatest output pre--- set in the factory
can, however, be reduced in level according to
actual system requirements; this does not affect
the maximum output in d.h.w. operation.
Such adjustments must be carried out by a quali-
fied person; therefore we advise you to contact
8
your installer or Service Agent.
Adjustment of the boiler temperature alters the
gas flow at the burner according to the thermal de-
mand in the system. So it is usual to see the burner
lit at the minimum level for more or less long
periods.
