2. Parameters with more than one description are reset to the default value if the parameter given in brackets is mo-
dified.
3. The Maximum Heating Power parameter can also be modified in Test Mode.
Press the Reset button to return to the Service Menu. Press the Reset button for 20 seconds to exit the card Service
Menu, or exiting occurs automatically after 15 minutes.
