Resetting To The Initial State; Error Codes And Device Led Feedback - HomeMatic HM-OU-CFM-Pl Operating Manual

9 Resetting to the initial state

The device can be reset to the initial state. Doing this deletes all
information relating to taught-in components.
To reset, proceed as follows:
• Press and hold down (for at least 3 seconds) the channel
button to switch the device to teach-in mode.
• The light flashes briefly. Press and hold down the channel
button again (for at least 3 seconds).
• The device LED flashes quickly to indicate that the actuator
has been reset to the initial state.
Resetting the device to the initial state only resets all
settings to the factory settings; it does not format the
microSDHC card.
