Functionality without limits

e.control offers numerous options for operating the lighting: Web services for browsers or IP telephones, touch panels, built-in room control devices and radio buttons that are integrated using corresponding receivers (dialog RC-E or lumina MS4/RC). All these permit the switching or dimming of lighting, the retrieval of scenarios and manual logging into or out of the room.

e.control multisensors form the core of any energy-efficient room, because automatic presence detection and measurement of room brightness are essential factors.

e.control light actuators are suitable for any lighting application. Whether fluorescent lamps, high- or low-voltage halogens or LED lights, whether relays, dimmers, 1-10V or DALI, e.control always has the right actuator available. All e.control light actuators incorporate power-on and power-off delays, a delayed light switch and a scene memory. Suitable installation locations include electrical distributors and decentralised system distributors.

The e.control occupancy evaluation determines the correct layout of a room from a combination of presence detectors and presence buttons for all other application functions for lighting, sunshade and room climate control. The holding time works adaptively and can be configured separately for each system.

Constant light control is the ideal way to save lighting energy and is therefore mandatory for any energy-efficient building. In rooms supplied with daylight, this system mixes in just enough artificial light to ensure that the required lighting level is maintained. In deep rooms with uneven distribution of daylight, e.control constant light regulation can even control two separate lighting groups. Thanks to a learning artificial lighting correction, even suspended lamps with an indirect portion are no problem for e.control. Energy savings can come to up to 50%.

The daylight-dependend switch is used when lighting cannot be or should not be implemented with a dimming option. Depending on the supply of daylight, artificial light is added – with e.control, this can even be a two-level process. A built-in learning function ensures that the lamps are turned back off once the daylight is sufficient.

The e.control automatic light only turns on the lights in halls, sanitary facilities, and storage rooms when people are detected. This avoids the use of energy for the lighting of unused rooms.

In the outdoor or entry area, in traffic routes or for the illumination of a building, lighting is only needed during the hours of darkness. Since the time of twilight varies from day to day, a twilight switch works autonomously to ensure the right time to turn on the lights. The e.control ombra W2 compact weather sensor uses its brightness sensor to turn on the desired light actuators at the right time – and turns them back off as well. The threshold values and delay times are configurable, of course.

e.control offers numerous operating options for the sunblind: Web services for browsers or IP telephones, touch panels, built-in room control devices and radio buttons that are integrated using corresponding receivers (dialog RC-E or lumina MS4/RC). All permit the positioning of curtain lengths and slat angles, either direct or using scenes.

For energy-efficient buildings, in addition to automatic presence detection, the determination of sun intensity and interior room temperatures are needed for the automatic positioning of the sunblind. e.control determines these values using multisensors, control devices, radio temperature sensors and weather stations.

e.control actuators cover the entire spectrum of sunblind drives, whether interior or exterior blinds, awnings, screens or roller shutters. All devices have built-in priority control and a scene memory for curtain positions, including angular position. All actuators also support e.control slat tracking control, including shadow correction. For particularly tough requirements, due to exact positioning accuracy, e.control SMI actuators are also available for 230V or 24V motors.

The e.control automatic solar control in the ombra W2 or ombra WSx weather sensors evaluates exterior brightness across the facade and determines the limit value above which and the delay with which a defined sunshade position will be selected in order to avoid subjecting the user to glare.

For energy-efficient buildings, sun position-dependent guidance of the slats is important. The e.control ombra BST slat tracking controller periodically calculates the exact angle at which the maximum daylight supply can be achieved without introducing glare, and sends it to the e.control sunshade actuators. The adjustment cycle and angle are parameterisable, as is the behaviour in case of temporary shadow.

Every e.control sunblind actuator is capable of determining autonomously whether its curtain will be in the sunshine at a specific time or shaded by (parts of) the building. This permits the sunshade to be adjusted to maximum transparency in the shadowed phases to improve the daylight yield.

To support heating or cooling, automatic thermal control is used to regulate solar energy entry through the facade. While heat input is welcome in the spring and thermal control opens the sunblind appropriately, in summer it prevents unnecessary heating by closing up. It is an integral component of all e.control devices and multisensors, providing the link between sunshades and HVAC systems needed for energy-efficient buildings.

The e.control weather protection system protects exterior curtains from damage by wind, freezing and even from precipitation. The e.control ombra WSx weather station uses its precise sensors to measure all the weather data needed, and brings the sunshade system into the defined safe position on a timely basis. Of course, different limit values and safe positions can be defined for different curtain types.
