A detached ventilation control (RMS705B, device 1) controls a rooftop fan
(RMS705B, device 2). To do this, a release command created in device 1 is sent as
transmission object via digital output and used by device 2 to start the rooftop fan.
Example 2
In reverse direction, any operating message created in device 2 is sent as
transmission object via digital output to device 1 and processed accordingly.
The following transmission and reception zones are engineered for the example:
