Configuration mode
By pressing the DHW- and DHW+ push buttons together for 10 seconds, it is possible to enter into the Configuration mode.
The display starts with showing “b01” blinking. By means of the CH “+” and CH “-” push buttons it is possible to select the
parameters; between “b01” and “b28”. Selecting one of these parameters, by means of the DHW “+” and DHW “-” push buttons
it is possible to adjust his value (not flashing). The value is automatically saved.
By pressing the DHW- and DHW+ push buttons together for 10 seconds, it is possible to leave the Configuration mode.
If no action has been taken, the MMI automatically leaves this mode after 2 minutes.
