3 Application/use
3.1 Intended use The switchgear is suitable for the pressure-dependent control of up to three pumps:
•Control EC-Booster: uncontrolled fixed-speed pumps
•Control ECe-Booster: electronically controlled variable-speed pumps
The signal is acquired using a pressure sensor.
Intended use includes compliance with this manual. Any other use is regarded as non-com-
pliant with intended use.
3.2 Improper use •Installation in potentially explosive atmospheres
•Overflow of the switchgear

3 LED indicators
4 LCD display
The front of the switchgear comprises the following main components:
•Main switch for switching the switchgear on/off
•Operating button for menu selection and parameter input
•LEDs for displaying the current operating state
•LCD display for showing the current operating data and individual menu items
The position of the individual operating elements is the same for the plastic and metal hous-
ing.
4.2 How it works The pumps are switched on/off individually and automatically depending on the actual
pressure in the system. The pressure control for the Control EC-Booster is carried out using
a two-point controller. The pressure control for the Control ECe-Booster is carried out us-
ing a PID controller. When the dry running level is reached, a visual signal is displayed and a
forced switch-off of all the pumps occurs. Faults are stored in the fault memory.

–Max. relative humidity: 90%, non-condensing
6.4.1 Basic advice on fixing the
switchgear in place
Various structures can be used for installation (concrete wall, mounting rail, etc.). For this
reason, the fixation material for the relevant construction must be provided by the cus-
tomer and the following information must be observed:
•To prevent cracks in the masonry and chipping of the construction material, ensure suf-
ficient clearance to the edge of the structure.

en
Installation and operating instructions • Wilo-Control EC/ECe-Booster • Ed.02/2023-08 11
•The depth of the borehole depends on the length of the screws. Drill the borehole ap-
prox. 5mm deeper than the screw length.
•Drilling dust impairs retention force. Always blow the borehole clean or vacuum it out.
•Do not damage the housing during installation.
6.4.2 Installation of switchgear Screw sizes for plastic housing
•Max. screw diameter:
–Control EC-B1x: 4mm

Installation
Attach the switchgear to the wall with four screws and wall plugs:
✓Switchgear is disconnected from the mains supply and is voltage-free.
1. Loosen the screws on the cover and open the cover/switch cabinet door from the side.
2. Align the switchgear on the installation site and mark the position for the drill holes.
3. Drill and clean the mounting holes in accordance with the specifications of the fixation
material.
4. Attach the lower part to the wall with the fixation material.
Check the lower part for deformations! Realign deformed housing (e.g. by placing
alignment plates below it) to ensure the housing cover closes securely. NOTICE!If the
cover does not close correctly, the protection class is compromised!
5. Close the cover/switch cabinet door and fasten it with the screws.
▶Switchgear installed. Now connect the mains supply, pumps and signal transmitter.
6.4.3 Low water level (dry-running pro-
tection)
The level can be measured via the following signal transmitters:
•Float switch
The float switches must be able to move freely in the operating space (pump chamber,
tank)!
•Pressure switch
•Electrode
–Only ControlEC-B/ECe-B1x... and EC-B/ECe-B2x...
A forced switch-off of all pumps always takes place in the event of an alarm, irrespective
of the selected signal transmitter!
6.5 Electrical connection
DANGER
Risk of fatal injury due to electrical current!
Improper conduct when carrying out electrical work can lead to death
due to electric shock!
• Electrical work must be carried out by a qualified electrician!
• Observe local regulations!

•Execute fuse protection on the mains side in accordance with the local guidelines.
•If circuit breakers are used, the switching characteristics should be selected according to
the connected pump.
•Follow local guidelines if residual-current devices (RCD, type A, sinusoidal current, uni-
versal-current-sensitive) are installed.
•Route connection cable in accordance with the local guidelines.
•Do not damage the connection cable during routing or installation.

6.5.3 Switchgear mains connection:
Control EC-Booster DANGER
Danger of death due to electrical current when the main switch
is switched off!
Even when the main switch is switched off, there is mains voltage power
to the voltage selection terminal.
• Make the voltage selection before connecting the product to the
mains.
CAUTION
Risk of property damage due to incorrectly set mains voltage!
If the wrong mains voltage is set, the switchgear will be destroyed. The
switchgear can be operated at different mains voltages. The mains
voltage is set to 400V at the factory.
• To use another mains voltage, change the position of the cable
jumper before connection.

Risk of property damage due to incorrectly set mains voltage!
The switchgear can be operated at different mains voltages. However,
the control voltage must always be 230V. If the control voltage is set in-
correctly, the control unit will be destroyed!
• The cable jumper is set to the correct control voltage as a factory set-

NOTICE!After all pumps have been connected, set the motor current monitoring!
6.5.6.2 Adjust motor current monitoring The minimum and maximum motor current of the connected pumps is monitored:
•Minimum motor current monitoring
The value is permanently stored in the switchgear: 300mA or 10% of the set motor cur-
rent.
NOTICE!Monitoring can be disabled in Menu 5.69.
•Maximum motor current monitoring
Adjust the value in the switchgear.
NOTICE!Monitoring cannot be disabled!
The maximum motor current is monitored in two different ways:
•Connected pumps with rated current up to 12A: electronic motor current monitoring
•Connected pumps with rated current greater than 12A: separate motor protection

Use a screwdriver to set the rated motor current at the respective potentiometer.
NOTICE!“0” setting on the potentiometer leads to an error when the pump is activated!
Precise adjustment of motor current monitoring can be performed during commissioning.
During commissioning, the set and the actual rated motor current can be shown on the dis-
play:
•Currently set value of the motor current monitoring (Menu 4.25 to 4.27)
•Currently measured operating current of the pump (Menu 4.29to4.31)
