10.3 Manual output
A manual output can be set with the Normal display of the display and operating unit or
via the PC software.
Manual output via the display and operating unit
Manual output can be activated or adjusted by keeping the F button depressed for at
least 1 second and by pressing the + or – button.
Output 0 means Manually off.
As long as manual output is active, the output appearing on the normal display blinks.
To deactivate and to change to automatic operation, press Esc for 3 seconds.
If Manually off is activated, it is stored via mains OFF.
On power return, the burner assumes the Manually off position (OFF blinking) (refer to
chapter Operation).
Fuel changeover resets the manual output to Invalid.
Exception:
Setting Manually off is maintained after fuel changeover also.
Activation of Manually off in operation
To activate Manually off, first run the system to the minimum output limit. Then, keep the
F button depressed for at least 1 second and press the – button.
Manually off is activated by releasing the F button and by pressing again the – button.
Caution!
Manually off must not be used by itself to put a burner out of operation when
doing mounting work, or when the burner is not ready for operation. The safety
notes in chapter Safety notes must be observed!
Manual output via the PC software
Refer to description of the PC software (J7352).
10.4 Output with curve settings
To set the curves via the display and operating unit or the PC software, a special
parameterization output is provided. Using this output, it is also possible to approach the
point of ignition. The output is delivered automatically and cannot be set manually. It is
only mentioned here for the sake of completeness.
