EAN: 7612914024909 - manufacturer-number: SSA955 - Synco Living - Radiator Control Actuator + RF-controlled actuator for radiator valves + RF communication based on KNX standard (868 MHz, bidirectional) + Battery-powered by commercially available 1.5 V batteries (reversed polarity protection) + Low power consumption + Silent mode (e.g. for use in sleeping rooms) + Nominal stroke 2.5 mm + Valve positioning force 110 N + Automatic identification of valve stroke + Parallel connection of multiple actuators possible + Integrated temperature sensor + For direct mounting with coupling nut (no tools required) + Manual adjustment Use: + For integration into the Siemens Synco 900 system + Suited for use in heating plant for operating radiator valves from Siemens or radiator valves of other manufacture + Several radiator control actuators can be used in one room Compatibility: Valves of other manufacture without adapter: The SSA955 can operate without adapter radiator valves of other manufacture provided they have a connecting thread M30x1.5 mm. The following makes satisfy these requirements and can be used with the SSA955: + Honeywell MNG + Cazzaniga + Heimeier + TA + Finimetall + Oventrop M30x1,5 + Junkers Other combinations on request. Valve preadjustment / kv limitation: To ensure optimum control performance, the valve’s volumetric flow should not be preadjusted. If preadjustments are required, refer to the relevant technical documentation on the valves for detailed information. The SSA955 supports valves with a stroke of > 0.5 mm (refer to paragraph “Calibration”). Scope of delivery: Each SSA955 is supplied complete with alkaline batteries and Mounting Instructions. Product documentation: The Operating and Commissioning Instructions for the SSA955 are contained in the product documentation of the central apartment unit. Functions: Main function: The SSA955 controls the room temperature based on the data delivered by the central apartment unit. Parallel operation: When using several SSA955 in one room, the first SSA955 integrated in the room operates as the lead controller. The other SSA955 are controlled by the lead controller via the central apartment unit. The multifunction button can be used to query the lead controller. The multifunction LED indicates when the SSA955 operates as lead controller. Binding: The binding is used by the SSA955 to sign on at the central apartment unit, thus integrating it into the RF system. The binding process is triggered via the multifunction button. It is indicated by the multifunction LED. Calibration: Every time a binding is established and every time the batteries are changed, the SSA955 automatically starts the calibration process. This ensures that the SSA955 will be optimally matched to the respective radiator valve. The SSA955 informs the central apartment unit if calibration could not be performed. If the valve’s stroke drops below the minimum, or if no valve has been attached to the actuator, the SSA955 will deliver an error message. If calibration was successful, the SSA955 will automatically switch to control mode. Silent mode: For use in rooms, such as sleeping rooms, where extremely quiet operation is required, the SSA955 can be switched to low-noise operation from the central apartment unit. Summer operation: Summer operation is triggered from the central apartment unit. When the SSA955 receives a command to start summer operation, the radiator valve will be opened or closed, depending on the position demanded by the central apartment unit. Antilime function: The antilime function is triggered by the central apartment unit according to a time schedule. When the SSA955 receives an antilime command, the radiator valve will be fully opened and fu - SSA955
