7. Follow-up
After switching off the current stage, the fan turns off after the set run time. The
length of the overrun time is adjusted by the DIP switches 3 and 4 (6, 10, 15, 21
minutes). If you switch between stages, the delay time will be ignored. By
simultaneous shut down of the both stages, applicable delay time can be ignored. As
always, the technical signal is faster, so the controller response will depend on the
last signal.
