No access to the coding
addresses for the parameters
of the combustion controller
11:9

12:0
Special function OFF
Always reset to 12:0 if
“possible change”
used.
12:1
12:2
Special function ON:
During calibration, the control automatically sets the boiler
water temperature to max.
If automatic calibration is initiated, the boiler will not start
unless the temperature falls below 42°C/108°F (see fault
Eb before adjusting).
21:0
No maintenance interval
(operating hours)selected
21:1
to
21:100
The number of hours run before the burner should be
serviced is adjustable from 0 to 100
(each increment = 100 hr.).
23:0
No time interval for burner
service selected
23:1
to
23:24
Interval adjustable from 1 to 24 months
24:0
The service display is reset
24:1
Service display (value displayed automatically)
28:0
No burner interval ignition
28:1
to
28:24
Time interval adjustable from 1 to 24 h. The burner is
force-started once for 30 sec. within selected time interval.
(only adjustable if coding address 82:_ has been set to 1).
2E:0
