e.control™ - All functions within one system!

Unique scope of functions

Due to the significance of automation for the energy efficiency, economy and ergonomics of a building, a new planning approach is needed which starts with the definition of the functionality within the room. With directive 3813 the VDI (German Association of Engineers) published, for the first time anywhere in the world, the methods required for the clear and comprehensive planning of room automation functions. It helps the technical planner to specify the requirements and the installer to implement them. Applied consistently, they offer the advantage that the complex, systemwide functionality of a highly efficient room automation system such as that required, for example, by efficiency class A of EN 15232, can be described in precise detail. Assuming that suitable systems are in place, this means for the installer that the commissioning is simpler and the subsequent building operation can be transparently and flexibly adapted for the user.

e.control is best prepared for the directive. e.control is probably the first system to offer the entire functional scope in accordance with VDI 3813-2. All functions are combined and optimally tuned. To ensure that your building work perfectly according to your wishes!

General Features

Time programs

Time programs

The e.control time programs can vary the room functions at specified times and adapt them to the room utilisation expected. Time programs for increasing energy performance, for example, adapt the operating modes of the room temperature controllers or switch off the lighting sysetms. Basically, all e.control room functions can be switched on via time programs so that a vast range of user requests can be met.

Occupancy evaluation

Occupancy evaluation

By means of occupancy sensors, e.g. in the lumina MS3 multisensor, e.control automatically recognises the presence of persons. With this information, the room automation functions for lighting, sunblinds or room climate control can be operated in a particularly energy-efficient manner.

Scene control (room utilisation types)

Scene control (room utilisation types)

Certain settings for lighting, sunblinds or room climate functions can be jointly stored in e.control in the form of scenes and called up at any time. The user can thus easily master the most complex room situations, for instance in conference rooms, by pressing a button. All spega devices serially possess a scene memory so that no special components are required.

 

Lighting, antiglare protection and daylight utilisation

Constant-light control

Constant-light control

A sensor for detecting the brightness of the room, e.g. in the lumina MS3 mulitsensor, makes sure that the lighting level is precisely adapted to the task to be performed.

e.control offers the requisite dimmable actuators for all standard lighting systems. Through optimum utilisation of daylight, the constant light controller in conjunction with the occupancy sensor is able to save more than 50% of the light energy.

Daylight-dependent lighting

Daylight-dependent lighting

The "younger brother" of the constant-light controller is used wherever the lighting is only of switchable design. Here too, a sensor is required in the room to detect the brightness. If the daylight is less than the required room brightness, artificial light is automatically switched on in one ore two stages and switched off again when the proportion of daylight increases. Here also, the combination with the occupancy sensor is recommended. The saving potential is up to 45%.

Automatic lights

Automatic lights

In rooms without sufficient supply of daylight, for example, in hallways or in sanitary rooms, energy can be saved by just temporarily switching on the lighting. The occupancy sensor provides the requisite sensor data for this. A settable cutout delay allows for lighting comfort. The potential energy savings depend considerably on the frequency of utilisation.

Automatic solar control

Automatic solar control

Blinds, above all, guarantee glarefree workplaces and are therefore indispensable despite the unavoidable reduction in the daylight coming into the room. The e.control automatic solar control system in conjunction with a weather station makes sure that the sunblinds assume an adjustable antiglare position whenever a certain intensity of sunlight is exceeded. After the  expiry of an adjustable delay period, the sunblinds move back automatically into the final position to ensure better supply of daylight in the case of cloudy skies.

Slat tracking control

Slat tracking control

The e.control slat tracking controller is the systematic further development of the automatic solar control system. In case of high intensity of sunlight, the sunblind moves into a position of the sun. The supply of daylight is thus maximised by preserving the anti-dazzle function. From the point of view of energy, the combination with constant-light controller is recommended which continuously responds to the optimisation and can thus once again save more than 10% of the lighting energy.

Shadow correction

Shadow correction

Surrounding buildings or parts of your own building produce shadows on the facades. This makes the anti-dazzle function unnecessary at times for the blinds which are in the shadow. The blinds should be kept open during this period for better supply of daylight. All e.control sunblind actuators are therfore equipped with a system which calculates the shading factors and works in conjunction with the automatic solar control or the slat tracking controller.

Automatic twilight control

Automatic twilight control

Whether for outdoors or indoors or for illuminating a building, the following applies: Light is only required when it gets dark. Since the time varies depending on the season, the automatic twilight control independently ensures that the light is activated at the best possible time. In addition to the lighting, the sunblinds can naturally also be positioned depending on the twilight.

Weather protection control

Weather protection control

The e.control weather protection control functions take the wind right out of the weather's sails. High-precision sensors for temperature, rain, wind speed and direction ensure that the ombra W8 sensor unit always keeps an overview of weather conditions and protects the blinds from wind, rain or frost well in time. Motoractuated windows are also included in the protection function.

 

Heating, cooling and ventilation

Energy mode selection

Energy mode selection

To enhance the energy performance, the operating modes Comfort, Standby or Economy can be selected individually for every room. Dedicated setpoints are allocated to these energy modes. A change-over can be carried out via time programs, manual operating buttons or occupancy sensors. A particularly energy-saving variation is to switch from Economy to Standby in the morning using a time switch. The function of the e.control occupancy sensor is to increase the setpoints to the Comfort level. In this manner, more than 20% of heating and cooling energy can be saved.

Sunblind thermal control

Sunblind thermal control

The sunlight entering through the windows produces heat input in the room which is eighter welcome or unwelcome energy depending on the room temperature. The e.control sunblind thermal controller controls the sunblinds in unoccupied rooms. In this manner, overheating is avoided in the summer and the load on the heating system is reduced in the winter through solar energy gains.

Free night cooling

Free night cooling

Cool night air can be used for cooling down the room temperature if windows or shutters can be opened by motor-actuation or if there are fan coils with air intake flaps. The e.control temperature controllers enable a decentralised free night cooling without additional devices.

Anti-frost protection

Anti-frost protection

To prevent damage by frost to the heating or cooling system, all e.control controllers have a Building Protection mode and a separate frost warning system.

Window monitoring

Window monitoring

In the event of windows being open, the e.control window monitoring system automatically stops the supply of heating or cooling energy to avoid energy wastage. The condition of the windows is read via contacts and reported to the e.control temperature controller. The savings attained amount to 10% of the heating and cooling energy.

Load optimisation

Load optimisation

The use of the integrated e.control system makes it possible for each mixer circuit to identify the room with the maximum energy requirement and to automatically adapt the inlet temperature to the load. This function eliminates losses of energy in the distribution system by means of a needs-oriented control system and thus replaces the traditional control by atmospheric conditions.
