9.7 Configuration storage/data storage
The electronic module is equipped with a non-fading memory for saving the configuration. If the power sup-
ply is interrupted for any length of time, all settings and data is retained.
When power is restored, the pump continues to run with the default values that were present before the in-
terruption.
NOTICE
The recorded operating data is stored in the data memory in a non-fading manner every
30 minutes. If the pump is switched off via the power supply before the 30 minutes have
elapsed, the data recorded since the start of the most recent 30-minute time period is not
stored. The data is then lost. It is therefore recommended to only switch off the pump via a
digital input with EXT. OFF.
The Wilo-Stratos MAXO is able to record and save a range of time-stamped data relating to its operating
time:
• Delivery head
• Volume flow
• Speed
• Feed and return temperature
• Hall temperature (in case of hall temperature control)
• Heating and cooling quantity
• Electrical power consumption
• Voltage
• Operating hours
• History of fault and warning messages
The history data can be presented over a desired period, e.g. the last four weeks. Aspects such as the hy-
draulic behavior of the hydraulic circuit being supplied or the current state of the pump can thus be analyzed.
During a period without any power supply applied to the pump, the time stamp is set continuously with the
help of a battery.
To view this data, the Wilo-Smart Connect app must be connected to the pump via Bluetooth or via Wilo Net
via the Wilo-Smart Connect Gateway. The data can then be read from the pump and displayed in the app.
10 Twin-head pump operation
10.1 Function
All Stratos MAXO pumps are equipped with an integrated dual pump management.
In the "Twin-head pump operation" menu, a twin-head pump connection can be established or discon-
nected. The twin-head pump function can also be set here.
The dual pump management has the following functions:
• Main/standby operation:
Each of the two pumps provides the configured flow rate. The other pump is available in case of malfunc-
tion or runs after pump cycling.
Only one pump runs at a time (factory setting).
The main/standby operation is also completely active even for two similar single pumps in a twin-head
pump installation in the Y-piece.
