DESCRIPTION OF THE PARAMETERS
Parameter 5 (2AF/32773):
Proportional part
The Proportional part in heating operation is a boiler specific value (not plant specific) and must not be changed.
Parameter 6 (2AG/32774):
Integral part
The Integral part in heating operation is a boiler specific value (not plant specific) and must not be changed.
Parameter 7 (2AH/32775):
Differential part
The Differential part in heating operation is a boiler specific value (not plant specific) and must not be changed.
Parameter 8 (2AI/32776):
Reference value when bus-interruption
If there is no bus connection between the automatic firing device and the heating controller, the automatic firing de-
vice adopts the reference value entered here.
Parameter 9 (2AJ/32777):
Max. temperature rise at low flow temperature
The temperature gradient defined here can be exceeded, up to the “low” flow temperature set in Parameter 11 (see
functional drawing 2). If this is exceeded, is resulted in a reduction in the number of rotations to the minimum rotation
number.
Parameter 10 (2AK/32778):
Max. temperature rise at high flow temperature
The temperature gradient defined here is deemed to be exceeded if it rises above the “high” flow temperature set in
Parameter 12 (see functional drawing 2). If this is exceeded, is resulted in a reduction in the number of rotations to
the minimum rotation number.
Parameter 11 (2AL/32779):
“Low” flow temperature
The parameter, necessary for controlling the temperature increase at low flow temperatures, can be assigned a
value here. See functional drawing 2.
Parameter 12 (2AM/32780):
“High” flow temperature
The parameter, necessary for controlling the temperature increase at high flow temperatures, can be assigned a
value here. See functional drawing 2.

Parameter 13 (2BC/32781):
Lock-out flue gas temperature
If the flue gas temperature, entered here, is exceeded, the automatic firing device is locked-out (“E:25”).
Parameter 14 (2BD/32782):
Blocking flue gas temperature
If the flue gas temperature, entered here, is exceeded, the automatic firing device is blocked (“B:07”).
