Frequently Asked Questions - 2912 BERKER

How do I install the Berker 2912 switch?

Installation should be performed by a qualified electrician. Ensure the power is off, connect the phase wire to the common terminal (usually marked L or COM) and the load wire to the other terminal. Secure the switch into the wall box and attach the cover plate.

What is the maximum load for the 2912 switch?

The switch is rated for 10 A at 250 V AC, corresponding to a maximum load of 2500 W for resistive loads. For inductive loads (e.g., motors), derating may apply.

Can the Berker 2912 be used for 3-way switching?

No, the 2912 model is a 1-way switch. For 3-way or intermediate switching, you would need additional compatible switches (e.g., Berker 2913 or 2914).

Is the 2912 switch compatible with dimmer modules?

The 2912 is a standard on/off switch and is not designed for dimming. For dimming functionality, use a dedicated dimmer switch from Berker's range.

What tools are needed for installation?

You will need a screwdriver (Phillips or flathead depending on terminals), wire strippers, and a voltage tester to ensure power is off before starting.

Can the switch be used outdoors?

The Berker 2912 has an IP20 rating, meaning it is only protected against solid objects larger than 12 mm and not against water. It is intended for indoor use only.

How do I clean the switch?

Wipe the surface with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the thermoplastic material.

What is the warranty period for Berker products?

Berker typically offers a 2-year warranty from the date of purchase. Always retain your receipt for warranty claims.

Are replacement parts available for the 2912?

Yes, common replacement parts include the rocker and cover plate. Contact Berker customer service or authorized dealers for specific parts.

Can I connect multiple switches in series?

Switches are typically connected in parallel rather than series. For controlling a light from multiple locations, use a multi-way switching setup with compatible switches.

Operation- and

Assembly Instructions

1 Safety instructions

Electrical equipment may only be installed and fitted by electrically skilled persons.

Failure to observe the instructions may cause damage to the device and result in fire and other hazards.

Danger of electric shock. Always disconnect before carrying out work on the devise or load. At the same time, take into account all circuit breakers that supply dangerous voltage to the device or load.

Danger of electric shock. Device is not suitable for disconnection from supply voltage.

Danger of electric shock on the SELV/PELV installation. Not suitable for switching SELV/PELV voltages.

Danger of electric shock. Do not operate the insert without a cover.

These instructions are an integral part of the product, and must remain with the end customer.

3 Function

Intended use

• Output Kanal 1 for switching light
• Output HLK for switching light, fans, air conditioners, thermostats and motors
• Operation with suitable cover
• Installation in appliance box to DIN 49073

Product characteristics

• Output HLK with potential-free NO contact for switching a second electric circuit, not SELV or PELV
• Switch-on delay of output HLK can be switched off
• Run-on time of output HLK adjustable
• Connection of extensions possible

Function with motion detector or presence detector cover

Output Kanal 1

• Output is switched on if motions are detected and the brightness is below the threshold set on the cover.
• Output remains switched on as long as motions are detected.
• Output is switched off if no more motions are detected and the run-on time set on the cover has elapsed.

Output HLK

• Switch-on delay switched on: output is switched on independently of the brightness after 3 minutes if additional motions are detected approx. 2.5 to 3 minutes after the initial detection.
• Switch-on delay switched off: output is switched on independently of brightness if motion is detected.
• Output remains switched on as long as motions are detected.
• Output is switched off if no more motions are detected and the run-on time set on the insert has elapsed.

Behaviour after a mains voltage failure

• Less than 0.2 seconds: switching state is retained
• longer than 0.2 seconds: both channels switch off. The behaviour after mains voltage return depends on the cover used (see instructions for the cover).

4 Operation

Switching on with pushbutton cover (see Accessories)

Operation on the main device, 2-wire extension or on the installation button is identical.

i Extension operation is only possible if there is a cover fitted on the main device.

Outputs are switched off.

■ Press the button.
Output Kanal 1 switches on.
When the switch-on delay for output HLK is switched off, output HLK switches on directly.
When the switch-on delay for output HLK is switched on, output HLK switches on with a time delay, if output Kanal 1 is switched on for longer than 3 minutes.

Switching off with pushbutton cover (see Accessories)

Outputs are switched on.

■ Press the button.

Output Kanal 1 switches off.

Output HLK switches off after the run-on time set on the insert elapses. The run-on time begins as soon as output Kanal 1 has switched off.

Switching on in combination with motion detector or presence detector

Operation is performed with a 2-wire extension or an installation button. Only an overview of the behaviour is provided here. For additional information, please refer to the instructions for the cover in question. Operation with an extension is only possible is there is a cover fitted on the main device.

Outputs are switched off.

■ Press extension.

Output Kanal 1 switches on.

When the switch-on delay for output HLK is switched off, output HLK switches on directly.

When the switch-on delay for output HLK is switched on, output HLK switches on after a time delay of 3 minutes, if no additional motions are detected for approx. 2.5 to 3 minutes after the extension is operated.

Switching off in combination with motion detector or presence detector

i Combination with motion detector: outputs cannot be switched off.
i Combination with presence detector: the output HLK cannot be switched off.

Outputs are switched on.

■ Press extension.

Output Kanal 1 switches off for 3 minutes. Any motions that are detected extend the time.

During these 3 minutes output Kanal 1 can only be switched on again via the extension.

5 Information for electrically skilled persons

5.1 Fitting and electrical connection

DANGER!

Electrical shock when live parts are touched.

Electrical shocks can be fatal.

Before carrying out work on the device or load, disengage all the corresponding circuit breakers. Cover up live parts in the working environment.

i Outputs Kanal 1 and HLK are not protected internally. For device protection, connect a 10 A miniature circuit breaker upstream.

■ Connect insert according to connection diagram (picture 2).
i Output HLK can be used to switch a second external conductor.
For extension units use the electric circuit of output Kanal 1.
i Illuminated installation buttons may only be connected if they have a separate N terminal.

■ Connect the extensions, optional.
■ Install insert in appliance box, terminals must be at the bottom.
■ If multiple miniature circuit breakers supply dangerous voltages to the device or load, couple the miniature circuit breakers or label them with a warning, to ensure release is guaranteed.
■ Set run-on time for output HLK (see Commissioning).
■ Attach the frame and the cover.
■ Switch on mains voltage.

5.2 Commissioning

DANGER!

Electrical shock when live parts are touched.

Electrical shocks can be fatal.

Before carrying out work on the device or load, disengage all the corresponding circuit breakers. Cover up live parts in the working environment.

Switching switch-on delay for output HLK on and off

The switch-on delay for output HLK can be switched on or off. In the sate as delivered the switch-on delay is switched on.

There is a pushbutton cover (see Accessories) on the HLK insert.

Outputs Kanal 1 and HLK are switched off.

■ Press button over entire surface for longer than 3 seconds.

When the switch-on delay is switched on for output HLK, only output Kanal 1 is switched on. After 3 seconds the switch-on delay is switched off; output Kanal 1 is switched off again as confirmation.

When the switch-on delay for output HLK is switched off, both outputs are switched on. After 3 seconds the switch-on delay is switched on; both outputs are switched off again as confirmation.

Setting run-on time for output HLK

Output HLK remains switched on for the run-on time, after output Kanal 1 has been switched off or no more motions are detected. The run-on time can be set in five stages between 2 minutes and 120 minutes.
