With 48 seconds remaining the control system gives a feedback about the filter test.
If the selected ”filter check value” is near the maximum air volume that the ventilation unit
can handle, the filter test will fail.
If a lower air volume is accepted in the week program, the filter test can be made
another time with a lower ”filter check value”.
But if a lower air volume isn’t accepted in the week program, the ventilation unit can’t
run with automatic filter surveillance.
In the configuration menu the function automatic filter surveillance (menu point ”Auto
filter surv.”) is then going to be disabled. See service engineer’s guide for further
information.
After 400 seconds (approximately 7 minutes) the ventilation unit is ready for use.
