Siemens’ portfolio undergoes continuous development to make it more secure. Siemens strongly recommends that updates are applied as soon as they are avail- able and that the latest versions are used. Use of versions that are no longer sup- ported, and failure to apply the latest updates may increase your exposure to cyber threats.

Commissioning Off-site commissioning (uninstalled) 2.2 Off-site commissioning (uninstalled) We do not recommend commissioning devices uninstalled since unique identifica- tion in the control system cannot be guaranteed if multiple radiator valve actuators of the same type are installed (they are merely identified in the system by type designation).
Operation Set temperature 3 Operation 3.1 Set temperature The setpoint temperature can only be set within the limits from the data point list. 1. Press one of the touch elements [1]. The display turns on. The present setpoint temperature is displayed. 2.

Operation Key lock 3.3 Key lock The actuator displays the setpoint temperature if the key lock is enabled and the user presses a touch element. The key lock must be disabled to change the tem- perature. Enable key lock ◈ Simultaneously press both touch elements and hold for 6...8 seconds [A].
The wink function identifies radiator valve actuators. This is especially useful in parallel mode. Wink availability depends on the network where the SSA911.02TH is integrated. 1. Simultaneously press both touch elements and hold for 2...4 seconds [1]. The display switches on and displays W (= "Wink").
Operation Error messages The SSA911.02TH sends a signal to the paired edge device. The radiator valve actuator is highlighted on the dashboard. The wireless radiator valve actuator display switches off after 10 seconds and the actuator goes into sleep mode.
Operation Change batteries 1. In the event of an error, press one of the touch elements to switch on the dis- play. E4, E5: The setpoint temperature is displayed for 1...2 seconds; you can change the setpoint during this time. ...
◈ Press the reset button in the battery compartment for approx. 10 seconds. A counter is displayed after 5 second to count from 5 to 10. The SSA911.02TH is reset to the factory settings. A6V16313372_en--_a 11 | 12...
