Function description

Vitocom 100, type GSM: Entering PIN code via Vitotronic

If a Vitocom 100, type GSM (accessories) has been
connected to the heat source, enter the PIN code on
the Vitotronic control unit.
After entry, you may have to wait 10 to 15 s.

Hydronic balancing

When carrying out hydronic balancing using the
"Hydronic balancing service case with Vitosoft 300",
"Hydraulic balancing ENABLED" appears on the
display.
While the function is enabled, it is not possible to oper-
ate the boiler via the Vitotronic control unit.

Electronic combustion control unit

The electronic combustion controller utilises the physi-
cal correlation between the level of the ionisation cur-
rent and the air ratio . The maximum ionisation cur-
λ
rent is achieved at an air ratio of 1 for all gas qualities.
The ionisation signal is evaluated by the combustion
controller and the air ratio is adjusted to a value
between =1.24 and 1.44. This range provides for an
λ
optimum combustion quality. Thereafter, the electronic
gas valve regulates the required gas volume subject to
the prevailing gas quality.

The boiler is unavailable for heating operation or other
functions during hydronic balancing. The burner does
not start.
To check the combustion quality, the CO
the O content of the flue gas is measured. The pre-
2
vailing air ratio is determined with the measured val-
ues. The relationship between the CO
and air ratio is illustrated in the following table.
