Menu structure
The CU331SP has a start-up guide, which is started at the first
start-up. After the start-up guide, the CU331SP has a menu
structure divided into four main menus:
1. GENERAL gives access to the start-up guide for the general
setting of the CU331SP.
2. OPERATION enables the setting of setpoint and resetting of
alarms. It is also possible to see the latest five warnings and
alarms.
3. STATUS shows the status of the CU331SP and the pump. It is
not possible to change or set values.
4. INSTALLATION gives access to available parameters.
11. Setting by means of the control panel

11.2 Back to factory setting

2. Press On/Off, OK and + while switching on the power supply.
The CU331SP will reset all parameters to factory settings. The
display will turn on when the reset is completed.
Warning
The On/Off button on the control panel does not
disconnect the CU331SP from the power supply
and must therefore not be used as a safety
switch.
The On/Off button has the highest priority. In
