Manual operation

Special device functions can be undertaken using the operating keys on the membrane keypad.
Operation via the membrane keypad is available and functions identically for all devices VC/S 4.2.1.
For a complete overview of the control elements, see Product overview.
Manual operation facilitates on-site operation of the device. Manual operation is enabled as standard and
can be switched on and off using the Manual operation button.
Manual operation can be permanently deactivated in the ETS.
The group object Status Manual operation indicates whether manual operation is enabled/disabled.
Switching on manual operation:
► Press and hold the Manual operation button for 5 seconds until the yellow LED illuminates continuously.
Switching off manual operation:
► Briefly press the Manual operation button.
 The yellow LED goes off.
The device is in KNX operation after connection to the KNX, bus voltage recovery, ETS download or
ETS reset. The LED is off.
The LED remains off if manual operation is disabled in general or disabled via the Enable/disable manual
operation group object.
A switchover from KNX operation to the Manual operation mode does not occur.
The control values calculated by the controller or received via KNX are overridden and ignored during
manual operation.
Changes due to manual operation are valid only while manual operation is active.
Manual operation cannot override forced operation or a safety state of the device.
Any override of the individual functions becomes effective only when they are changed for the first time
by pressing a button. Until then, the outputs continue to react to values received from the controller or
via KNX.
