7.1 Installation
Wall-mounted installation: Dimensions, see Fig. 3
7.2 Electrical connection (Fig. 4a-f)
DANGER! Risk of fatal injury!
When working on the open switchgear, there is
a danger of electric shock from touching the live
components.
Have the electrical connection established by an
electrician approved by the local electricity supply company only and in accordance with applicable regulations.
The current and voltage of the mains connection
must correspond to the details on the rating
plate of the pump to be connected / of the

CAUTION! Risk of malfunctions!
If power consumption falls below 1 A during
operation, (idling power), reset the device by
pressing the 'RESET' button (Fig. 1, item 6).
8.1 Selecting the operating mode
A 3-way selector switch (button) is used to select
the operating mode on the front of the switchgear
(Fig. 1; item 5):
“MANU” (button) position: the system is manually controlled, regardless of the level setting or
external control components.
Position “0”: the pump cannot operate. It remains
deactivated in all circumstances.
Position “AUTO”: the pump operates automatically based on the selected system.
8.2 Settings and tests

Three-phase 400 V:
Four-core cable (3 phases + earth) on contact
(item 3) to terminals 2-4-6
Single-phase 230 V:
Three-core cable (1 phase + neutral + earth) on
contact (item 3) to terminals 2-4
7.2.2 Connect external elements
DANGER! Risk of fatal injury!
Poor earthing can lead to electric shock.
• Connect the earthing cable with the terminal
strip (Fig. 2, item 5)
• Do not connect an external voltage to terminal
strip (Fig. 2, item 4).
It is possible to perform remote control using an
external control element (pressure switch, control, level control, etc.). Connection via a two-core
cable Ø 0.75 mm

to the terminals 5 + 6 of the terminal strip (see Fig. 2; item 4); beforehand,
remove the bridge between terminals 5 + 6.
Connect the cable to the terminal strip based on
the intended application (see Fig. 2, item 4 and
Fig. 4;. see Chapter 6.3).
8.2.1 Overload protection
DANGER! Risk of fatal injury!
Make all settings when the pump is deactivated.
• Set the potentiometer (Fig. 2, item 6) to the rated
motor power specified on the rating plate (or for
submersible pumps, on the equipment label near
the switchgear).
• Set three-way switch (Fig. 1, item 5) to 'AUTO' the green signal lamp lights up and the pump
starts.
If the fault light comes on within 3 minutes, the
rated power is set too low.
• Before changing settings, check the motor
power consumption and the connections.
• Reset the rated power based on the determined
values.

English
8.2.2 Check direction of rotation
(3-phase motor only)
Keep three-way switch (Fig. 1, item 5) at the position 'MANU' (the 'Mains voltage' signal lamp lights
up). When there is a signal (float switch, electrode,
etc.), the pump starts.
For direction-of-rotation control, follow the
instructions for commissioning the pump.
If the direction of rotation is incorrect:
• Switch off the plant
• Switch two phases in the switchgear.
8.3 Selecting the operating mode
Depending on the application, an operating mode
must be set.
8.3.1 Installation with two electrodes (Fig. 4a)
• Select low-water protection (Fig. 2, item 11)
• Configure the sensitivity of the electrodes
Before the pump is started, set the water conductivity potentiometer (Fig. 2, item 7) to the minimum value.
Make sure that the electrodes are immersed and
the three-way switch (Fig. 1, item 5) is set to position 'AUTO'. Slowly turn the potentiometer (Fig. 2,
item 7) clockwise until the pump starts.
• Applying the electrodes
(see the pump operating instructions)
NOTE:
The lower electrode reports low water. The upper
electrode must be immersed in order to reset this
error.
8.3.2 Installation with one electrode (Fig. 4b)
CAUTION! Risk of malfunctions!
Select low-water protection (Fig. 2, item 11)!
• Configure the sensitivity of the electrode
Before the pump is started, set the water hardness
potentiometer (Fig. 2, item 7) to the minimum
value.
Make sure that the electrodes are immersed and
the three-way switch (Fig. 1, item 5) is set to position 'AUTO'. Slowly turn the potentiometer (Fig. 2,
item 7) clockwise until the yellow signal lamp
(Fig. 1, item 2) starts to flash.
• Set the time delay before restarting
After stopping due to low water, the pump will
start with a delay (1 to 30 minutes).
The delay is preset in the potentiometer (Fig. 2,
item 8).
During the waiting period, the yellow signal lamp
flashes (Fig. 1, item 2).
• Applying the electrode
(see the pump operating instructions)
8.3.3 Installation with flow meter (Fig. 4c)
CAUTION! Risk of malfunctions!
Set water hardness potentiometer to its maximum value (Fig. 2, item 7)!
• Select low-water protection (Fig. 2, item 11).
• Set the time delay before restarting
After stopping due to low flow rates, the pump will
start with a delay (1 to 30 minutes). This delay
allows for sufficient filling of the water tank
before a restart.
The delay is preset in the potentiometer (Fig. 2,
item 8).
During the waiting period, the yellow signal lamp
flashes (Fig. 1, item 2).
• Configure the time delay before a restart (Fig. 2,
item 9)
To provide the flow meter with enough time to
record a sufficient flow rate, a minimum period
operating time (5 seconds to 3 minutes) is configured for the pump. If the flow meter has not been
activated after this time has elapsed, the pump
will stop.
• Activating the time delay functions
(Fig. 2, item 12)
“AUT” position:
Both delays are active
“MAN” position:
The restart is triggered by pressing the 'Reset'
button (Fig. 1, item 6).
CAUTION! Risk of malfunctions!
Make sure that the bridge between terminals 5 + 6
on the terminal strip (Fig. 2, item 4) is correctly
positioned.
8.3.4 Pumping operation
CAUTION! Risk of malfunctions!
Set water conductivity potentiometer to its
maximum value (Fig. 2, item 7)!
Operation with one float switch (Fig. 4d)
• Select low-water protection (Fig. 2, item 11).
In this position, the float switch is connected to
terminals 5 + 6 of the terminal strip (Fig. 2, item 4).
• Connect a protection switch (as dry running protection) to terminals 1 + 3 of the terminal strip.
• Set the time delay before restarting
After stopping due to low water, the pump will
start with a delay (1 to 30 minutes).
The delay is preset in the potentiometer (Fig. 2,
item 8).
During the waiting period, the yellow signal lamp
flashes (Fig. 1, item 2).
Installation and operating instructions Wilo-Control ESK1, PSK1 15
English
Operation with two float switches (Fig. 4e)
• Select low-water protection (Fig. 2, item 11).
In this position, the device only activates the
pump and the yellow signal lamp (Fig. 1, item 2)
displays the filling phase.
CAUTION! Risk of malfunctions!
Make sure that the bridge between terminals 5 + 6
on the terminal strip (Fig. 2, item 4) is correctly
positioned.
8.3.5 Pressure boosting (Fig. 4f)
CAUTION! Risk of malfunctions!
Set water hardness potentiometer to its
maximum value (Fig. 2, item 7)!
Float switch in the tank + pressure switch
• Select low-water protection (Fig. 2, item 11).
In this position, the pressure switch is connected
to terminals 5 + 6 of the terminal strip (Fig. 2,
item 4).
• Set the time delay before restarting
After stopping due to low water, the pump will
start with a delay (1 to 30 minutes).
The delay is preset in the potentiometer (Fig. 2,
item 8).
During the waiting period, the yellow signal lamp
flashes (Fig. 1, item 2).
Pressure switch in the inlet pipe + pressure
switch
• Select low-water protection (Fig. 2, item 11).
