In a Corrigo with 3 ports, both serial ports have the same function. They can, however, not be
configured to have the same function at the same time.
17.29.3 BACnet communication
In order to connect a Corrigo running a ventilation application to a SCADA system via BACnet/IP
or BACnet MS/TP, a third generation Corrigo with a TCP/IP port or RS485 port is required. For
BACnet MS/TP, a BACnet router must be used. BACnet communication cannot be activated via the

17.30 Other parameters
17.30.1 Start and stop delays for the fans
Use start delay if you wish one of the fans to start before the other and for example if you wish to
give the close-off dampers time to open before starting the fans. Use stop delay e.g. to create a cool-
down period when using electric heating. In order to avoid letting in too cold air, e.g. in the winter,
the heat exchanger will continue to run during the stop delay.
Delay SAF
Start: 60 s
Stop: 30 s
Delay EAF
Start: 0 s
Stop: 30 s
17.30.2 Retardation time
When switching two-speed fans from 1/1-speed to 1/2-speed there is a settable retardation time. The
same time applies to both fans.
