Introduction
● Usage: Application program usage
● Product family: HVAC valve actuators
● Manufacturer: Siemens
● Name: SSA KNX Networked Actuator
● ASN: SSA118.09HKN
Function overview
Workflow
If no application has been downloaded (factory setting), the actuator enters construction
mode immediately following self-calibration. In this mode, the actuator has limited functionali-
ty and the valve position is set to 25 % to prevent freezing of the radiator. You can change
the valve position via group address 30/0/26 (0xF01A).
After users download the configuration with PL-Link controller, the actuator will then work in
PL-Link mode.
Use ETS5 (Engineering tool software) to download the application via KNX bus after the ac-
tuator is connected to bus voltage. The following basic functions are available when the ac-
tuator is operated in KNX S-Mode:
● By using central heating boilers with demand-controlled flow temperature, the device
sends feedback on current energy demand (current max. valve position) via group ad-
dress to the central heating boiler.
● Operating modes available in KNX S-Mode: Forced mode, summer mode, emergency
mode, override control mode, night mode, and office mode.
HMI (button and LED)
The KNX programming button and KNX programming LED are designed as per the design
concept of the KNX device, defining common use of KNX programming mode, stimulation for
a connection test and factory reset (multi-color mode). See the datasheet for details.
The stem position LED indicator is intended for motor behavior. It indicates different actuator
movements. See the datasheet for details.
Factory reset
Use the KNX programming button or the KNX bus command to reset the device.
When switching between PL-Link and S-mode, remember to do a factory set.
