Overview of coding addresses
Coding (factory default setting)
System design
00 :1 System type 1, 2:
1 heating circuit without mixing valve,
without DHW heating
Boiler/Burner
06:... Maximum limit of the boiler water
temperature, defaulted by the boiler
coding card
07:1 Boiler number in multiboiler
system (only with Vitocontrol-S and
Vitotronic 100 control)
11:≠9 No access to the coding
addresses for the parameters
of the combustion controller
12:0 Special function OFF
Always reset to 12:0 if
"possible change" used.
21:0 No maintenance interval (operating
hours) selected
23:0 No time interval for burner service
selected
24:0 The service display is reset
28:0 No burner interval ignition
2E:0 KM-BUS connection of power/pump
module not recognized
2F:0 2F:0 Air bleed program/fill program disabled Air bleed program/fill program disabled
32:0 *1 Influence of the signal "External
blocking" on circulation pumps:
All pumps in control function
*1
Generally, the burner will be blocked when signal "External blocking" is enabled.
Possible change
00 :2 System type 1, 2:
1 heating circuit without a mixing valve, with DHW heating
00 :3 System type 3, 6, 8:
1 heating circuit with mixing valve, without DHW heating
00 :4 System type 3, 6, 8:
1 heating circuit with mixing valve, with DHW heating
00 :5 System type 4, 5, 7:
1 heating circuit without mixing valve and 1 heating circuit
with mixing valve, without DHW heating
00 :6 System type 4, 5, 7:
1 heating circuit without mixing valve; 1 htg. circuit with
mixing valve, with DHW heating
06:20 Maximum limit of the boiler water temperature within the
to ranges defaulted by the boiler coding card
06:127
07:2 Boiler number 2 to 4 in multiboiler system (only with
to Vitocontrol-S and Vitotronic 100 control)
07:4
11:9 Access open to the coding addresses for the
parameters of the combustion controller
12:1 Special function ON:
During calibration, the control automatically sets the boiler
water temperature to max.
12:2 If automatic calibration is initiated, the boiler will not start
unless the temperature falls below 108°F / 42°C (see fault
Eb before adjusting)
21:1 The number of hours run before the burner should be
to serviced is adjustable from 0 to 100
21:100 (each increment = 100 h)
23:1 Interval adjustable from 1 to 24 months
to
23:24
24:1 Service display (value displayed automatically)
28:1 Time interval adjustable from 1 to 24 h. The burner is
to force-started once for 30 sec. within selected time interval
28:24 (only adjustable if coding address 82:_ has been set to 1).
2E:1 KM-BUS connection of power/pump module automatically
recognized
2F:1 Air bleed program enabled
2F:2 Fill program enabled
32:1 Influence of the signal "External blocking" on
to circulation pumps: see the following table
