6.6 DTC, Down Time Cleaning
Down time cleaning is activated differently, depending on the mode selected.
With the DTC mode 1, down time cleaning is started via contact 7, 8 (fan stop: Contact 7, 8 must open).
With DTC mode 2, down time cleaning after deactivation of the fan is started only if the differential
pressure has exceeded the value „dP DTC Max“ (Parameter 18) during operation. Contact 7, 8 must
open).
