Use ● ● ● ● ● ● ● For radiator valves, VDN.., VEN.., VUN.. For Siemens PICV (pressure independent combi valves) VPP46.. and VPI46.. For MiniCombi valves VPD.., VPE.. For small valves VD1..CLC For radiator valves (M30 × 1.5) from other manufacturers without adapter Typically in radiator, chilled ceiling, VAV and fan coil unit applications Max.10 units of SSA161.05HF/SSA161E.05HF are able to operate in parallel, provided the controller output suffices. NOTICE SSA161E.05HF is only compatible with VPD.., VPE.
DC 0...10 V control signal (for SSA161.05HF) ● ● ● ● The valve opens / closes in proportion to the control signal at Y. At DC 0 V, actuator stem extended, the valve is fully closed. When no power is supplied, the actuator maintains its current position. This actuator provides a DC 0…10 V position feedback signal proportional to the stroke of the actuator stem. Y = Control signal Y [V] H = Percentage of calibrated valve stroke DC 0...10 V control signal (for SSA161E.05HF) Combi valves VPI46../VPP46..

Orientation Installation A [mm] B [mm] C [mm] 5.5 4.2 50 Crimp ferrule on stripped wire of connecting cable. ● Observe all admissible temperatures (see “Technical data [▶ 11]”). ● ● ● Do not twist the cable. Magnets can damage the actuator. Provide a means for isolation from the power supply, e.g., connecting a circuit breaker or switch fuse upstream of the control unit.
NOTICE The actuator must be commissioned only with a correctly mounted valve in place! Self-calibration When operating voltage is applied, the actuator self-calibrates (fully retracted ➙ fully extended ➙ setpoint). CAUTION Never intervene manually during self-calibration. NOTICE ● Correct calibration is only possible with valve stroke > 1.2 mm. Valve stroke < 1.2 mm results calibration failure. ● If calibration fails, the actuator performs another calibration automatically after 10 seconds.
WARNING If operating voltage is switched on, press button (a) before and after adjusting the position of the actuator stem. If you switched off operating voltage and control signal, you can adjust the position directly without pressing button (a). Maintenance The actuators require no maintenance. WARNING Operating voltage must be switched off during any maintenance! NOTICE When carrying out service work on the plant, note the following: ● Switch off operating voltage.
