5.8.3 SCR system programming and display unit
The programming and display unit provides all relevant
information about the exhaust gas post-treatment
system. It provides information about the status and
processes of the SCR system.
This programming unit is used to enter all relevant
SCR parameters, calculate the AdBlue
TM
metering
quantity, activate the metering devices for compressed
air and AdBlue
TM
, and monitor the system for faults. It
is not possible to change the process parameters at
operator level; this can only be done by Viessmann
Service.
