Initial start-up
Further step-by-step instructions (continued)
Matching the control unit to a modulating burner (Vitotronic 100, GC1)
Please note:
The burner must be fully adjusted. To achieve a wide modulating range, set the minimum output as low as possible
(observe the chimney and flue gas system).
1. Start up the burner.
2. Set the override switch to .
3. Wait until the burner actuator is set
to maximum output.
4. Determine the maximum burner
output through the fuel
consumption.
Record the relevant value.
5. Press 9 and simultaneously for
approx. two seconds.
Relay test is activated.
6. Activate the mod. burner close
function with (display shows: 4),
and set the override switch to a.
Check the time it takes until the
actuator is at minimum output.
Record the relevant value.
7. Determine the minimum burner
output (basic load) through the fuel
consumption.
Record the relevant value.
8. Activate the mod. burner open
function with (display
shows: 2), and set mod. burner
neutral function (display shows: 3)
using , after 1/3 of the time
checked under item 6 (stop burner
module controller).
9. Determine the partial output
through the fuel consumption.
Record the relevant value.
10. Press .
Relay test is completed.
11. Set the determined values in
coding 1, see the table below and
on page 154.
Address Setting of
08 Units and tens of the determined maximum output;
e.g. max. output: 225 kW – set here: 25
values including 199 kW can be entered directly.
09 Hundreds of the determined maximum output;
e.g. max. output: 225 kW – set here: 2
15 Determined run time in seconds
0A Relationship between basic output and max. output in percent; e.g.
basic output: 72 kW
max. output: 225 kW
72 kW
225 kW
x100 % = 32 %
05 Relationship between partial output and max. output in percent; e.g.
partial output: 171 kW
max. output: 225 kW
171 kW
