Matching the coding addresses to the system version (cont.)
Matching the control unit to a modulating burner
Note
The burner must be fully adjusted. To achieve a wide modulating range, set
the minimum output as low as possible (take the chimney and flue gas
system into account).
1. Start up the burner.
2. Set the emissions test switch to
"h" (see page 127).
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 K and d simultaneously
for approx. 2s.
Relay test is activated.
6. Activate the "mod. burner closed"
function with a (display
shows:4), and set the emissions
test 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 (base load) through the
fuel consumption.
Record the relevant value.
8 Activate the "Mod. burner open"
function with b (display:2), and
after g, the time checked under
item 5, activate the "Mod. burner
neutral function" (display:3) with
a (stop actuator).
9. Determine the partial output
through the fuel consumption.
Record the relevant value.
10. Press d.
Relay test is completed.
11. Set the determined values in
code 2, see page 104 and page142.
