FAQs

There are several advantages when dimming lighting, whether manually or automatically, based on daylight:

• Energy savings, achieving a rational use of lighting and reducing electricity consumption.
• Comfort, by adjusting the lighting level to people's actual needs and creating different lighting ambiances at different times of the day.
• Visual well-being, by reducing artificial lighting based on the natural light available at each moment of the day.

Unlike Incandescent or Halogen lamps, LED lamps must meet the condition that they or the built-in driver are dimmable. Therefore, the following can be dimmed:

• Dimmable LED lamps
• LED lighting fixtures or downlights with 1-10V or DALI drivers
• 12V and 24V LED strips
• Dimmable 230V LED strips
• Incandescent and Halogen lamps
• Fluorescent tubes with 1-10V or DALI ballasts

It depends on the type of lamp to be controlled:

• 230V LED lamp: must be dimmable.
• 12V LED lamp: must be dimmable and connected to an electronic transformer, not a ferromagnetic one.
• 230V LED strip: must be dimmable.
• 12Vdc to 48Vdc LED strip: all low-voltage LED strips can be dimmed without the need for the associated power supply to be dimmable.
• LED lighting fixtures or downlights: must be accompanied by a dimmable 1-10V or DALI Driver.

Both work by cutting the Voltage in various phases of the sine wave of the 230V alternating current, thus reducing the energy supplied to the lamps.
In leading-edge dimming, the dimmer cuts the wave early in the power signal cycle, shortly after the signal crosses the zero point.
On the other hand, in trailing-edge dimming, the dimmer cuts the wave in the last moments of the phase cycle of the power signal, just before the zero crossing of the signal.
The choice between the two depends on the load (lamp or luminaire) to be controlled, which determines which of the two technologies to use.

Indeed, phase-cut dimming involves reducing the energy supplied to the lamps, and, consequently, their consumption is decreased.

Dimmable 230V LED Strips must be controlled with phase-cut Dimmers, which are the same ones used for dimming LED Lamps.

Leakage current compensator

Constant light controls, or daylight harvesting systems, are sensors that enable luminaires to automatically dim based on the available natural light at any given time, continuously compensating for its absence with the necessary artificial light.
These sensors also include a motion sensor, which further allows the illumination of the luminaires to be adjusted according to the presence of people in the room.
Their most common applications include school or university classrooms, offices, medical centres, warehouses, etc.

For old installations where you cannot pass wires or carry out works, the direct solution without touching the installation would be with our RE PLA LE0 2-wire Led lamp dimmer. It will be a direct replacement of the switch that turned on the LED lamp with a push button and the RE PLA LE0 dimmer installed behind the mechanism itself. It is a direct substitution without manipulating the installation.

The uses of Motion Detectors are quite diverse.
Their main application is the control of lighting or HVAC systems based on the presence of people within their detection range.
Some common uses of Motion Detectors include:

• Energy Saving: Used to automatically turn lights and other electrical devices on and off when the presence of people in an area is detected. This helps save energy and reduce electricity costs.
• Comfort Automation: used in automation systems to activate/deactivate lighting or air conditioning automatically when the presence of people is detected.
• Street Lighting: Used in street lighting systems to automatically turn on lights when the presence of people or vehicles is detected, helping to save energy and improve safety.

In summary, motion detectors are highly useful for automatically triggering electrical and electronic devices when motion is detected, which helps save energy and automate various systems.

There are mainly 2 types of motion detectors for lighting control:

• Infrared (PIR): A PIR (Passive Infrared) motion detector senses the infrared radiation emitted by objects within its field of view. When an object moves within the sensor's detection range, the infrared radiation emitted by the object changes, and the detector sends an activation signal.
• High Frequency (Radar): An HF (High Frequency) motion detector emits high-frequency radio waves in the detection area and measures changes in the frequency of the reflected waves. When an object moves within the detection range, there is a change in the frequency of the reflected waves, indicating motion. This type of detector can be concealed as it penetrates any non-metallic material."

Zero-crossing control (ZCT) involves switching the relay of Motion Detectors when the 230V sinusoidal wave crosses the horizontal axis, thereby minimizing the current peaks generated at that moment. Thanks to this, it is possible to switch high loads without the risk of damaging the relays or having them get 'stuck' after a certain number of operations.

The simplest solution without changing the installation in the neighbourhood would be to directly replace the push button with our 2-wire motion detector DM CAM 003 and select the impulse mode. The installation diagram would be as follows.

Infrared Motion Detectors (PIR) detect the infrared radiation emitted by objects within their field of view. When an object moves within the sensor's detection range, the infrared radiation emitted by the object changes, and the detector sends an activation signal.
Likewise, air currents themselves can trigger the PIR sensor and subsequently turn on the lighting without the presence of people.
To prevent or minimize these false activations, it is sometimes necessary to reduce the detection sensitivity of the devices. Depending on the detector, this can be achieved by simply adjusting the sensitivity using the corresponding potentiometer or by using a compatible Remote Control for the specific detector.

Thanks to the 2 channels of a Time Switch, 2 circuits can be controlled independently, with 2 completely different schedules.
A common example could be controlling garden lighting with one channel and the pool pump with the second channel.

DINUY Digital and Astro Time Switches incorporate a interchangeable battery with an approximate life of between 6 and 10 years, depending on the model.

Within the DINUY catalogue, it is possible to find Digital or Analog Time Switches that occupy 1 module of width.

Efectivamente, gracias a los Interruptores Horarios Anuales de DINUY es posible realizar programaciones anuales discriminando
ciertos días del año.

An Astro Timer allows for the activation and deactivation of, for example, a lighting circuit based on the location and the timing of sunrise and sunset for each day of the year. 
To do so, it comes pre-programmed with the Astronomical calendar, and simply by indicating its position through coordinates, postal code, or Smartphone GPS, the device knows when sunrise and sunset occur every day of the year. 
This type of device is commonly used for controlling public lighting.

The main advantage lies in the fact that an Astronomical Switch turns on and off depending on the Sunrise and Sunset and the location, adapting automatically depending on the day of the year.

Indeed, within the DINUY Catalog it is possible to find call extenders for a conventional door chime or for an intercom with buzzer call:

CALL EXTERNDER TRANSMITTER 8-24V - EM HEB 004

CALL EXTENSION TRANSMITTER 110-220V - EM HEB 005

In a very simple way by manipulating the 2 DIPs that are on the button itself. From the button, by moving the DIPs you can select the desired melody among the 32 melodies that the doorbell has and set a desired melody. The steps to follow are the following:

1. DIP 1 and DIP2 in the OFF position.
2. You press the push button until you select the desired melody.
3. DIP1 stays OFF and DIP2 you change it to ON.

If you do not want to do any work or any type of installation, the simplest option is to select our range of wireless doorchimes sets via radio frequency. You do not need to run any cables between the push button and the wireless doorbell. The wireless KITs are as follows:

• TI HEB K26: Push button + battery-operated bell KIT 100m.
• TI HEB K28: Push button + battery- operated bell KIT 200m.
• TI HEB K27: Push button + 230V plug-in doorbell KIT 100m.

An Impulse Relay is an electronic device that allows the switching on and off electrical circuits, mainly lighting, using one or multiple parallel push buttons. With each press, the output of the Impulse Relay changes its state, either closed or open, without the need for a continuous voltage supply to the coil as in a conventional relay. One of its main advantages lies in the simplicity of wiring compared to an installation with switches and cross-connections.

The most common applications are in the residential sector and in hotels. The main application is to install remote switches with pushbuttons in parallel instead of switching or crossing. It has 3 great advantages to use remote switches:

• Installation is easier. Wiring is simplified in addition to using less length in meters of cable.
• You install push buttons, which is the most economical element of the series of mechanisms in front of the switch or the crossing.
• Telerruptor is a very silent electronic element.

Indeed, one of its most common applications is the use of Impulse Relays for turning the lighting on and off from the headboard in hospitals, hotels, or even residences.
