2.5 Integration via KNX bus
The RDG2..KN room thermostats can be integrated as follows:
● Integration into Synco 700 system via LTE-Mode (easy engineering)
● Integration into Desigo via group addressing (ETS) or individual addressing
● Integration into third-party systems via group addressing (ETS)
The following KNX functions are available:
● Central time program and setpoints, e.g., when using the RMB795B central
control unit
● Outside temperature or time of day via bus displayed on thermostat
● Remote operation and monitoring with web browser using the OZW772 web
server
● Maximum energy efficiency due to exchange of relevant energy information,
e.g., with Synco 700 controllers (e.g., heating demand, cooling demand)
● Alarming, e.g., external fault contact, condensation, clean filter, and so on
● Monitoring input for temperature sensor or switch
Engineering and commissioning can be done by using:
● Local DIP switches and HMI
● Synco ACS
● ETS5 or higher versions
● Siemens smartphone application PCT Go for Android
The RDG2..KN room thermostats are especially tailored for integration into the
Synco 700 system and operate together in LTE-Mode. This extends the field of use
of Synco for individual room control in conjunction with fan coil units, chilled
ceilings and radiators.
