For more information about parallel operation and the max. number of actuators
that can be used, refer to the data sheets of the selected actuator type and the
following list:
Max. number of actuators in parallel on RDG20..KN (AC 230 V):
● 6 SS..31.. actuators (3-position)
● 4 ST..23../ST..321 if used with On/Off control signal
● 10 SFA.., SUA.., MVI.., MXI.. On/Off actuators
● Parallel operation of SAS31 not available
Max. number of actuators in parallel on RDG20..KN (AC 24 V):
● 6 SS..81.. actuators (3-position)
● 4 ST..73../ST..121 if used with On/Off control signal
● 2 SFA71.. On/Off actuators
● Parallel operation of SAS81 not available
Max. number of actuators in parallel on RDG26..KN (AC 24 V):
● 10 SS..61.. actuators (DC)
● 10 ST..23/73../321/63/121 actuators (DC or On/Off)
● 10 SFA.., SUA.., MVI.., MXI.. On/Off actuators
● 10 SAS61.. actuators (DC)
● 10 GDB161.9E
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
– Max. 60 RDG2..KN per line and do not mix RDG2..KN with other KNX
products on the same line
● Integration into Desigo CC via IP router
● 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
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.
