The control of both pumps starts from the main pump to which the differential pressure
sensor is connected.
In case of breakdown/fault/communication interruption, the main pump alone takes over
complete operation. The main pump runs as a single pump according to the set operating
modes of the twin-head pump.
The standby pump, which receives no data from the differential pressure sensor, runs in the
following cases at an adjustable constant emergency operation speed.
• The main pump to which the differential pressure sensor is connected fails.
• The communication between the main pump and the standby pump is interrupted.
The standby pump starts immediately after detecting a fault.
In the "Twin-head pump operation" menu, a twin-head pump connection can be established
or disconnected and the twin-head pump function can also be adjusted.
Settings of

mode etc.
In the "Settings" menu
1. Select twin-head pump operation.
Menu "Twin-head pump function"
When a twin-head pump connection is established, the "Twin-head pump function" menu is
used to switch between
• Main/standby operation and
• Efficiency-optimised peak-load operation (parallel operation)
.
Menu "Pump cycling interval"
If a twin-head pump connection is established, the time interval can be set in the "Pump
cycling interval" menu. Time interval: between 1 h and 36 h, factory setting: 24 h.
An immediate pump cycling can be triggered via the menu item "manual pump cycling".
Manual pump cycling can always be carried out regardless of the configuration of the time-
based pump cycling function.
Menu "Connecting twin-head pump"
If twin-head pump connection is not yet established, in the "Settings" menu
1. "Twin-head pump operation"
2. "Connecting twin-head pump".
When the Wilo Net connection is established (see "Wilo Net [} 205]" section), a list of avail-
able and appropriate twin-head pump partners will appear under "Connecting twin-head
NOTICE
For the installation of two single pumps to form a twin-head pump, see
sections "Twin-head pump installation/Y-pipe installation" [} 149],
"Electrical connection" [} 150] and "Application and function of the Wilo
Net interface" [} 205].

NOTICE
When switching between main/standby operation and parallel operation,
different parameters of the pump are fundamentally changed. The pump is
then started automatically.
NOTICE
The pump from which the twin-head pump connection is started is the
main pump. Always select the pump to which the differential pressure
sensor is connected as the main pump.
