FUNCTION DESCRIPTION:

\n- The KNT-OT-Box S serves as an interface between the boilers with OpenTherm (bus system in heating and ventilation technology) and the KNX system (building system technology) \n- This enables the bidirectional exchange of data between the OpenTherm boiler and the heat distribution via the KNX system (individual room control) \n- In combination with the OT-Box (9070712) from the RAMSES 856 top2 OT (8569132) also heating systems without OpenTherm interface can be controlled \n- Device and KNX bus module can be swapped independently of each other \n- Removable KNX bus module \n- Button for OT-test-program \n- The following functions are available with the KNT- OT-box: \n- Customised flow control \n- Weather-compensation flow control \n- Control of domestic hot water \n- Energy optimization of domestic hot water with solar support \n- Legionella protection program \n- Screed drying program \n
