1. Connect the COM connector of the relay to the positive terminal of the
power connector next to the IO-Connector.
2. Connect the relay NO port to one of the digital inputs DI1, DI2 or DI3.But-

Input (open drain)
Use this configuration to switch an open-drain ouput. The open-drain
output can be regulated by an external system. This allows you to connect
an external system to the WaveNet. Note that the switching behaviour is
inverted:
Open drain of the signal generator open/unswitched: Pull-up resistor
"pulls" the digital input to +3.3 V
DC
(high level). An event is detected for
this input.
Open drain of the sensor closed/switched: Input is short-circuited to
ground (low-level).
