Vitotronic 100, GC1B Installation and Service
Category 2 "Boiler"
Coding in the Delivered Condition
0C:5 Modulating isolation valve, independent of the
set boiler water temperature.
0d:2 With Therm-Control, affects the isolation
valve (function disabled with code "0C:1").
13:... Shutdown differential in K.
The burner is switched off when the set boiler
water temperature is exceeded.
Delivered condition specified by the boiler
coding card.
14:... Minimum burner runtime in min.
Delivered condition specified by the boiler
coding card.
15:10 Runtime servomotor modulating burner 10 sec.
16:... Burner offset with start optimization in K
(temporary reduction of the set boiler water
temperature after burner start).
Delivered condition specified by the boiler
coding card.
1A:... Start optimization in min.
Delivered condition specified by the boiler
coding card.
1b:60 Time from burner ignition before control starts
60 sec.
1C:120 Signal B4 at plug fA is not available:
Compensation of signal delay for hours run
meter.
Time from burner start signal initiation at T2
in plug fA to opening of the solenoid valve.
At each burner start, 120 sec. will be taken
off the runtime.
1F:0 With flue gas temperature sensor:
Flue gas temperature is not monitored
for service display.

Possible Change
0C:0 No function.
0C:1 Constant return temperature control.
0C:2 Time-controlled isolation valve.
0C:3 Isolation valve switching subject to the boiler
water temperature.
0C:4 Isolation valve modulating subject to the set
boiler water temperature.
0d:0 Without Therm-Control.
0d:1 With Therm-Control, affects the mixing valves
of downstream heating circuits.
13:0 Without stop differential.
13:2 Stop differential adjustable from 2 to 20 K.

1C:1 Delay adjustable from 1 to 199 sec.
to This time is deducted from the operating time
1C:199 for every burner start.
E.g. operating situations in which the burner
is shut down via the mechanical adjustable
high limit, but a burner demand is still present
(hours run continue to be counted).
If required, change coding address "06".
