Electromotoric actuator SSA118.09HKN With KNX communication for radiator valves, PICV and small valves ● ● ● ● ● ● ● A6V11858280_en--_b 2021-08-06 Support of KNX S-Mode (integration with ETS) Support of KNX PL-Link (integration with Desigo™ Room Automation) Direct mounting with coupling nut, no tools required Position and actuator motion indication (LED) Positioning force 100 N Parallel operation of multiple actuators possible Integral cable length 1.
Product and application description The valve actuator SSA118.09HKN is suitable for installation on radiator or zone valves. It supports KNX PL-Link and S-Mode. It receives the setting commands via the KNX bus line from a room temperature controller (RTC). The valve actuator with integrated bus coupling unit is connected via a bus connecting block to the KNX bus line. The power supply results from the bus voltage. The valve adjustment works in proportion to an electromotive drive.
HMI (Human-Machine Interface) Overview 1 Protective cover for manual operation. Use a screwdriver to open before manually adjusting the actuator stem position. 2 Enable/disable button of manual operation 3 Hand adjustment with hex key for manual operation 4 KNX programming button 5 Stem position LED indicator 6 KNX programming LED Enable/disable button of manual operation Activity Button operation Confirmation Enter/exit local override mode Press button > 3 s.
Protection against unintended KNX programming button pressure The actuator provides a mechanical function to prevent accidental pressure of the KNX programming button. NOTICE Fully align A and B illustrated in Step 5 when reassembling the actuator. Addressing and bus test with the KNX programming button Press the KNX programming button (< 2 s) to set the actuator to addressing/programming mode: ● KNX bus wiring OK → LED turns red until addressing/programming is finished.

● ● If re-mounting to another valve is necessary, dismantle the actuator from the current valve by rotating the actuator stem anti-clockwise. See Mounting instructions enclosed with the product package for graphical instructions. Orientation Installation A [mm] B [mm] C [mm] 4.35 4.2 70 Crimp ferrule on stripped wire of connecting cable. ● Observe all admissible temperatures (see “Technical data [▶ 12]”). ● Operate the actuator only with alternating current (see “Technical data [▶ 12]”).
NOTICE Commission the actuator only with a valve mounted correctly in place! Self-calibration The actuator self-calibrates (fully retracted ➙ fully extended ➙ setpoint) after initial connection of bus voltage, after every download of the application, and after bus voltage recovery. During calibration, the valve is measured and the positions for “valve open” and “valve closed” are stored.
3. Adjust the actuator stem position by rotating the manual operation button clockwise or anti-clockwise. The actuator stem moves down if you rotate clockwise; it moves up if you rotate anticlockwise. The manually set position is retained. 4. If you want to exit the manual operation mode, press and hold down the enable/disable button of manual operation for at least three seconds. The actuator self-calibrates automatically. A control signal sent from the controller takes effect. 5.
