After the installation of a new mainboard the TYPE (binary) of the module is normally
automatically detected. The specific TYPE tells the pump how to configure itself during turn
on. In some cases, especially when a defective mainboard is replaced with an older version
of mainboard, the automatic TYPE detection does not work. When the TYPE of the
exchange main board does not match the pump, a pump configuration error will occur
during pump turn on. This will cause the pump status indicator to be red. In this case the
TYPE of the module has to be entered using the procedure described in the following
sections.
