Service mode
If the Service switch is in the „Service“ position
when the unit is switched on, the unit’s Service
mode is activated (pump does not run).
Selecting the service functions
The available service functions are selected via
the water temperature setting (1).
Example: 30 °C corresponds to the „ON30MIN“
function.
For several functions the functional selection
must already be set when the unit is switched on
and the Service switch must be held in the „SET“
position.
Example: RFIDONOFF is accessed with the
setting 45 °C + „SET“ on switching on.
Changing the settings
The current setting is displayed via the 10
indicator LEDs on the control panel.
The settings can be changed with the help of the
Service switch’s Inching function (turn to „SET“
position, switch jumps back to „Service“
function). The change is also displayed via the
indicator LEDs.
Quitting Service mode
– Switch off unit.
– Set Service switch to the appropriate water
hardness or „OFF“.
– Switch on unit.
