7. Replacing/Resetting the Master Controller

7.1 When?

• If the Master Controller in an existing CF2-system is reset to factory settings or
replaced with another Master Controller, it is necessary to reset all the other
CF2-system components also, in order to be able to re-install them to the reset or
replaced Master Controller, CF-MC !

7.2 How?

Note: The Master Controller should only be "Reset" to factory settings if the normal in- and unin-
stallation procedures can not be followed!

• Disconnect the 230V power supply to the Master Controller until the power
LED is OFF
• Press and hold at the same time the menu selection button
and the output selection button
• Reconnect the 230V power supply to the Master Controller and release the three
