G..B181..1E/KN VAV compact controller for KNX LTE-Mode Desigo and third-party The RDG..KNX devices can be integrated into the Siemens building automation systems and control systems (BACS) Desigo or 3rd-party systems. For integration, either S- Mode (group addressing) or individual addressing can be used. The workflow for integration into Desigo is the same as with standard KNX devices.

The switching differential or proportional band is 2 K for heating mode and 1 K for cooling mode (adjustable via P30 and P31). The integral action time for modulating PI control is 5 minutes for the RDG400KN and 45 minutes for the RDG405KN (adjustable via P35). Display The display shows the acquired room temperature or the Comfort setpoint, selecta- ble via P06.
Note When engineering with the ETS tool, the time of day can only be displayed on the RDG400KN when Synco group address 30/3/254 is loaded into the thermostat. For further details, refer to Basic Documentation [6], "Communication via KNX-bus for Synco 700", section "Engineering of big systems with ETS".
