• Volume flow threshold: depending on the signal
transmitter; directly on the flow switch or in
menu 5.19
• Switch-off time delay (menu 1.06)
• Pumps are enabled (menu 3.01)
• Pumps are in automatic mode
(menus 3.02 to 3.04)
If corrections are necessary, proceed as in the sec-
tion "Operation".
3. The switchgear is now ready for operation.
8.3 Checking the motor direction of rotation
At the factory, the switchgear for a clockwise
rotating field is checked for correct direction of
rotation and set.
Observe the wire designations on the connection
diagram when connecting the switchgear and the
connected pumps.
NOTICE
If the error code "E006" appears on the display
after activation, the mains connection has a phase
fault. 2 phases/conductors of the power supply on
mains side to the switchgear need to be swapped
over.
The rotation control of the connected pumps can
be performed using a test run. To do this, manual
mode needs to be started for each pump via the
menu.
1. Select EasyAction or the relevant menu item
for the corresponding pump:
• Pump 1: Menu 3.02
• Pump 2: Menu 3.03
• Pump 3: Menu 3.04
2. Select the value "HAND". The connected
pump runs as long as the operating button is
pressed.
3. If the direction of rotation is correct and the
pump is to be used for automatic mode, select
"AUTO".
4. If the direction of rotation is wrong, 2 phases/
conductors of the mains supply to the pump
supply conductor need to be swapped.
8.4 Adjusting the motor protection
The motor protection is adjusted according to
section 6.2.3.
8.5 Signal transmitters and optional modules
Comply with the installation and operating
instructions for signal transmitters and optional
additional modules.

9 Maintenance
DANGER! Risk of fatal injury!
There is a risk of fatal injury from electric shock
when working on electrical devices.
• The switchgear should be voltage-free and
secured against unauthorised switch-on during
any maintenance or repair work.
• Any damage to the connection cable should only
ever be rectified by a qualified electrician.
• Have maintenance and repair work carried out
by qualified personnel only!
• The switch cabinet must be kept clean.
• Check the earth contacts for burn-off from time
to time, and renew them if there is significant
burn-off.
10 Faults, causes and remedies
DANGER due to electrical voltage!
Improper procedures during electrical work may
result in fatal injuries caused by electrical volt-
age! This work may only be performed by a qual-
ified electrician.
Possible faults are shown on the display as an
alphanumeric code. According to the fault shown,
the connected pumps or signal transmitters must
be checked for correct function and replaced if
necessary.
Only perform this work if you have suitably quali-
fied personnel. For instance, electrical work must
be carried out by a qualified electrician. We rec-
ommend always having this work carried out by
Wilo customer service.
Any unauthorised modifications to the switchgear
are made at the operator's own risk and void the
manufacturer's warranty obligations.
10.1 Fault indication
Faults are displayed in various ways:
• When a fault occurs, the red collective fault
signal LED lights up and the collective fault signal
is activated. If the internal buzzer is activated,
there is an additional acoustic alarm signal.
The error code is shown on the display, continu-
ously alternating with the main screen. Addition-
ally, the error code can be read from the fault
memory.
• The acoustic alarm and the alternation between
the main screen and the error message can be
suppressed by pressing the operating button
once.
• Faults that only lead to switching operations once
a set time has elapsed are signalised by a flashing
fault signal LED.
The error code is shown on the display, continu-
ously alternating with the main screen.
Additionally, the error code can be read from the
fault memory.
