FAQ

RCD is an abbreviation of the English term “Residual Current Device”. In Germany, RCDs are called fault current protection switches or FI protection switches. An RCD is a switch that can interrupt the circuit electromagnetically. This is necessary if, for example, fault current flows through a person due to an insulation fault. The fault current is determined by means of a comparative measurement of the outward and return current of the electrical consumer. If the return current does not correspond to the outward current, this triggers the FI protective switch. The trip occurs so quickly that the user is immediately protected. For personal safety protection, only RCDs with a rated fault current of <= 30 mA may be used.

The MCB has a RESET position, i.e. in the case of an overload or short circuit, the switching knob jumps to the middle position (RESET). Thus, the device indicates an error in its circuit itself, which lead to it being triggered. After removing the fault, press the knob down until it clicks into position; the switch knob can then be moved to the ON position again.

The circuit of the consumer can also be switched ON or OFF from there. Switch position is visible (0/I)

The difference between B and C characteristics is in the area of the course circuit actuator. While the B characteristic triggered at 3-5 times the value of the rated current, the value for the C-characteristic changes to 5-10 times the value. This makes the C characteristic particularly suitable in areas where high inrush currents flow (e.g. circular saws, motors, etc.). The B characteristic is the standard for house installation in Germany.

The following socket strips are available with surge protection: POWERversal, MULTIversal, UNOversal, DUOversal

Manufacturers have not been permitted to sell socket strips with 1 mm² since 01/01/2010. For retailers, there is no deadline for selling socket strips with 1 mm².

In the case of a power strip with master/slave function, several slave sockets are switched depending on a master socket, i.e. if the consumer at the master socket is switched on, the other sockets are also switched on.

The distance is 71 mm. This measure applies for all switch programmes.

The room thermostat is to be operated at 220-250V~, the maximum load is 10 A~ for resistive load and 4 A~ for inductive load, X stands for solid fluorescent lamps.

The terminals of the UP/AP-shockproof socket are tested for rigid cables or wires. In the case of flexible cables, the wires are usually tin-plated. However, for safety reasons flexible cables may not be connected to UP/AP shockproof sockets as a rule, even if they are connected to the terminals after the tin-plating. The use of ferrules is not allowed either.

General information on installation can be found in the practical tips section and on our installation blog. Unfortunately, we cannot provide detailed instructions or exact connection information over the phone as we are not familiar with your installation and the situation on the ground. Always observe our safety instructions and the currently valid provisions and, if in doubt, ask a local expert for advice.

Possible errors: a) glow lamp is incorrectly installed in the switch (remedy – turn glow lamp 90° or 180° in the socket) (b) no neutral conductor connected (in contrast to the O/T switch, a neutral conductor must also be connected)

If the load is switched off (bulb), the glow lamp lights up as an orientation light in the dark.

Here, the metal spring drive is still sitting on the switch base. This must be removed and plugged in again after repositioning the frame. (Please note the diagram on the packaging!)

This antenna socket is designed as a single socket and not as a pass-through socket.

The steel core of the transformer consists of individual metal layers that may contain air inclusions. When dimming, a slight hum can be generated. If you therefore recommend an electronic transformer, pay attention to the VA power of the phase dimmer.

No, the centre hole is for removing the child protection cover. The child protection cover is pressed onto the base of the socket, finished. The shockpoof socket screw must not under any circumstance be used to affix the child protection cover. The image on the packaging shows an arrow and not a screw.

If the load is switched off (bulb), the glow lamp lights up as an orientation light in the dark.

A conventional transformer has a steel core wrapped in copper and is therefore larger and heavier than an electronic transformer. An electronic transformer is smaller and lighter. A conventional transformer is required when dimming a phase control dimmer, an electronic transformer is required for a trailing-edge phase dimmer.

Here, the metal spring drive is still sitting on the switch base. This must be removed and plugged in again after repositioning the frame. (Please note the diagram on the packaging!)

Yes, the dimmat combined with a button results in a toggle switch, which can even be dimmed using the button.

In order to protect the device itself, we have a time-lag 1.6A fuse (part number 3264 00087) upstream. Pull the fuse holder up and replace the fuse in place there

A detailed description of the different types of cables and usage options can be found in the “Practical Tips” section.

The cable cross-section depends on the type of routing, the current load and the length of the cable. In order to calculate the minimum cross section, an authorised electrician should be consulted.

The dimability of LED lighting products depends among other things on the lamp ballast used. The lamp must always be dimmable according to the manufacturer, i.e. operating instructions or information from the manufacturer! Even if the LED lamp is dimmable, one must take into account that each 2-wire dimmer requires a base load to function securely, i.e. flicker free. With a “normal” phase control dimmer (Triac dimmer), dimmable LED-bulbs can usually be dimmed. The base load specified for these dimmers can usually be reduced by a factor of 2-4, i.e. for a 40W base load, LED lamps from approx. 10W are also dimmable. This is not the case for phase angle control dimmers that require an operating voltage, such as the DIMMAT, in order to function, which has to react to the sensor surface being activated. For these dimmers, such “standby” power consumption can lead to the connected LED lamps flickering, which in turn depends on the structure of the ballast unit. There are ballasts that have so-called bleeder resistors built-in for this “purpose”, which is essentially supposed to ignore this “standby” power; however this is not always clear from the manufacturer. Therefore the current recommendation is that (even dimmable) LED lamps should not be operated using the DIMMAT. Since the nature of the ballast of the LED-bulbs is not known to us, an eventual malfunction or possible defect cannot be excluded. The current limited by the fuse of a standard 400W dimmer can in any case be sufficient to destroy the LED lamp. In this respect, it must be stressed once again that the instructions of the LED lamp manufacturer must be strictly observed.

In principle, only dimmable ESL and 230V – LEDs can bedimmed, i.e. it must be explicitly stated on the light sources. In most cases, you will find information on the lamp packaging about which dim procedures (phase angle control and/or trailing-edge phase dimmer) can be used to dim the lamp. In view of the large number of different integrated ballasts, the lamps are usually made to be compatible with the commercially available dimmers by the lamp manufacturer. With the Kopp phase angle control dimmer (R and RL)[except dimmat] most dimmable ESL and 230V LEDs can be dimmed.

For our phase control dimmer (dimmer/dimmat for conventional transformers), you need a time-lag 1.6A fine wire fuse. Our phase control dimmers (dimmers for electronic transformers) are equipped with an electronic fuse, which does not have to be replaced.

This is quite easy. Use two radio receivers with dimming functions to do so. Just be sure to note whether you have an electronic or a conventional ballast. Then programme your radio wall switch to both radio receivers. For each dim operation, both radio receivers are controlled simultaneously by the radio wall switch and the lamps are dimmed at the same time. Furthermore: You can also programme multiple radio wall switches to the two radio dimmers. Then make it into a radio dimmer toggle switch

The steel core of the transformer consists of individual metal layers that may contain air inclusions. When dimming, a slight hum can be generated. If you therefore recommend an electronic transformer, pay attention to the VA power of the phase dimmer.

A dimmer is generally not suitable for this application. This requires a special speed controller that we do not carry in our range

A conventional transformer has a steel core wrapped in copper and is therefore larger and heavier than an electronic transformer. An electronic transformer is smaller and lighter. A conventional transformer is required when dimming a phase control dimmer, an electronic transformer is required for a trailing-edge phase dimmer.

Yes, the dimmat combined with a button results in a toggle switch, which can even be dimmed using the button.

In order to protect the device itself, we have a time-lag 1.6A fuse (part number 3264 00087) upstream. Pull the fuse holder up and replace the fuse in place there

This is due to physical reasons. The coil in the device may be producing an audible vibration when dimming.

Yes, instructions can be found under “Practical Tips” in the Free-control® section.

No, the free-control software can only run on 32-bit operating systems. Installation and configuration within a virtual machine are possible however.

The 2-channel receiver/shutters 8080.0202.8 has an active power of approx. 1.5W.

With all the FC wall switches and FC hand transmitters, a receiver with dimming function can be used for ON/OFF/dimming functions. FC motion detectors and FC timers can only be ON/OFF. FC smoke detectors, gas detectors, heat detectors and alarm control panels can only be switched on by a programmed dim receiver.

The receiver with button/time function has an active power of approx. 1.1W.

The dimensions are L4 6mm x B4 7mm x H26mm

The active power is approximately 1.1W.

During the programming process, two buttons on the remote control or wall switch were probably pressed. In two button mode, it can only switch ON with one button and OFF with the other. Dimming only works in “1-button mode”. Solution: Reset device. Press the PROG key and hold for at least 10s. Re-programme the transmitter with just one button. If a wall switch is to be switched and dimmed with both buttons, the process is to be repeated with the second button. The distribution to two separate programming processes results in “double 1-button mode”. Both buttons can now be used to dim.

The 2 wire receiver 8080.0302.9 has an active power of approx. 0.5W.

We offer radio wall switches in Paris arctic white, Europe arctic white, standard cream (suitable for B+J DURO 2000) and standard alpine white (suitable for B+J Reflex Si) designs.

LEDs can only be switched directly using 3-wire receivers. These are as follows: – Receiver 1channel 3-wire 8080.0102.7 – Receiver with button/time function 8080.0402.0 – Receiver 2 channel 8080.0202.8 8115.0002.1 lamp socket 8115.0002.1 – radio adapter 2921.0102.9.

Fluorescent lamps can only be switched directly using 3-wire devices. These are as follows: – Receiver 1channel 3-wire 8080.0102.7 – Receiver with button/time function 8080.0402.0 – Receiver 2 channel 8080.0202.8 8115.0002.1 lamp socket 8115.0002.1 – radio adapter 2921.0102.9.

The radio wall switch can be stuck to the wall, screwed onto the wall or secured to a flush-mounted switch box. The necessary mounting material is enclosed in each package.

No, the system is very simple and can be set up without any special programming knowledge. Simply press the “PROG” button on the receiver and then the button on the desired transmitter with the enclosed programming pin. That’s all. The system learns independently.

Yes, all current Free-control products of the current generation can be combined with each other. This means that all Free control senders can be combined with all Free-control receivers. This provides you with a very high degree of flexibility.
The exception to this is generation 1:
Generation 1 was produced up to 2006. This in turn is not compatible with the current generation. The difference is easy to identify.
The Free control-logo for the first generation had a circle around the logo. For generation 2, the Free-control lettering has three radio waves.
Only devices with the same logo on the product are compatible.

You can also dim electronic ballasts using a Free-control radio receiver with dimming function. Our service department has a list of the ballasts tested by us and rated as good. Simply call the service number: 0618 8-40-417 and we will be happy to help you.

Simply remove the conventional wall switch. Use the 2-wire radio receiver (8080.0302.9) and connect the two wires to the radio receiver. Then you only need to programme the radio wall switch to the radio receiver. Proceed as described in the operating instructions. And the installation is finished. This will only take you a few minutes. And all this without any dirt or additional expense.

This is not possible. Free-control is a unique system that provides you with many advantages and benefits. In order to protect your Free-control installation against being randomly accessed by other systems, we have a transmission code that is unique worldwide. This makes the Free-control system extremely reliable and safe.

No worries. Nothing will happen. Normally an incorrect battery polarity is not possible due to existing mechanical measures. If this should occur, then the electronics detect the polarity reversal and switch off. The devices will not be broken.

The battery life is approximately 1.5 years at an average of 20 radio transmissions per day. We recommend replacing the batteries every year.

Each receiver has an internal storage capacity for programming up to 16 transmitters. These can be wall switches, motion detectors, hand-held transmitters or alarms.

Yes, you can of course programme additional transmitters to the receiver at any time. The previously programmed devices remain saved and are not deleted.

Yes, all alarms can be connected to each other via radio link. Thus, a water alarm can sound the smoke alarm or the gas alarm.

No. The radio transmitters are supplied with battery voltage. This voltage is not dangerous to children. Therefore, these devices can be operated safely by children. Please ensure that the children do not place small parts including the batteries in their mouth and swallow them.

The devices have a special battery saving mode. The life of the battery is about 1.5 years. For your own safety, we recommend replacing the battery after one year. Our tip: Use the alarm station as well and programme your alarms to the alarm station. As soon as the alarm loses battery power, a “low battery” message is sent to the alarm station and you will see from a glowing LED that the battery should be replaced as soon as possible.

This is almost impossible. The Free-control system has more than 65,000 different codes which are

assigned consecutively. This ensures a very high level of security against unauthorised operation.

The receiver in adapter form need only be plugged into the shockproof socket, the light receiver must simply be screwed into an E27 lamp socket. The flush-mounted receiver can be installed in UP switch boxes, UP distribution boxes, in the lamp canopy or on the DIN rail of distribution boards using the mounting clip.

Not normally. The radio dimmers are fitted with fuses, which usually turn off in the case of an overload or short circuit. Other devices are protected by their circuit breakers. Please be sure to use the correct circuit breaker for your house installation.

This is not possible. You can only delete all programmed transmitters at once. Use the enclosed programming pin to do so. Press the “PROG” button for longer than 10 seconds. If the memory has been deleted, the LED flashes, indicating successful deletion.

This is only possible in the case of button switches. There, you can select the radio receiver button for the existing current surge relay in parallel. You can then use the existing wired buttons and turn the light on and off using the additionally installed radio wall switch.

No. The programming is retained even after a power failure for an unlimited period of time and does not have to be repeated.

No problem. You only need a landline connection to connect the phone dialler. Then speak your own text into the device and enter the desired telephone number, which is to be dialled in the event of an alarm. You don’t have to do anything else.

The open-field range is approximately 150. Within a normal single-family house, two floors can easily be accessed. Of course, the achievable transmission range is affected by structural conditions and environmental influences. Therefore, we recommend testing the transmission path before installing.

Up to 32 alarms can be connected to each other via radio link.

This is quite easy. Programme the additional radio wall switch to the existing radio receiver. You have then assigned two wireless wall switches to one radio receiver. All you have to decide then is where to install the second wireless wall switch. And the toggle installation is finished. Another tip: If you would like further on and off options, simply programme more wireless wall switches to the receiver, making a toggle switch into an intermediate switch circuit. Furthermore: It could not be simpler, and all without any dirt or effort. This procedure only takes a few minutes.

All radio receivers can be switched using this. You can open and close your shutters or extend or retract your awning using a timer. Furthermore, this timer can be used to simulate presence. This means that, during your absence the lights switch on and off at different times and the shutters open or close. Exactly as you please. Any burglars will think that the house or apartment is inhabited.

Yes, the devices can be operated to a minimum temperature of -10 degrees Celsius. Please note that sub-zero temperatures can reduce the radio range and battery life.

In particular, the frequency is distinguished by low interference and high transmission security. Cheap products usually work in the 433 MHz range.

Theoretically, you can control an unlimited number of radio receivers within the transmission range. The radio signal is received by all radio receivers at the same time.

Simply delete your programming on the receiver and restart the programming, exactly as you would like it to be. Please note the enclosed operating instructions.

Press the button marked “PROG” for at least 7 sec., Diode flickers -> All programmes are deleted.

In particular, the frequency is distinguished by low interference and high transmission security. Cheap products usually work in the 433 MHz range.

The InfraCONTROL uses a time-lag 1.6A fine fuse to protect the device (part number 3264 00087).

For inductive loads, 3-wire devices are to be used. Here we carry different variants: e.g. the flush-mounted variant (part number 808402013) or surface damp room variant (part number 821302017).

2-wire: The Phase(L), and the lamp wire are connected; switchable loads: only incandescent lamps and 230 V halogen lamps; min./max. load 40-400W These devices are suitable for replacing a toggle switch. 3-wire: The Phase(L), the neutral conductor and the lamp wire must be connected (important: no protective conductor); switchable loads: resistive and inductive loads are possible, observe the min. load 40W.
