e.controlTM - unlimited functionality

Due to the significance of automation for the energy efficiency, economy and ergonom-ics 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 Associa-tion 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, system-wide 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 com-missioning is simpler and the subsequent building operation can be transparently and flexibly adapted for the user.

VDI 3813 describes how to deal in principle with flexible-axis buildings using segmentation as well as describing over 45 detailed functions connected to lighting, sunblind as well as HVAC systems and the necessary exchange of information between them. Industry-standard aids such as automation diagrams and function lists adapted for the directive are used for descriptive purposes.

As one of the first room automation systems, e.control is best prepared for the direc-tive. The modular design of the M-series, for example, supports the concept of the segment and room-oriented automation of flexible buildings without having to make any compromises whatsoever. Furthermore, e.control is probably the first system to offer the entire functional scope in accord-ance with VDI 3813. For this the LonMark functional objects of the e.control system were adapted such that they covered the functional definitions of VDI 3813 as far as possible. In this way it is possible to integrate the technologically-independent functional definitions of the planning stage on a one-to-one basis into the project plan-ning for the e.control system. Adaptations or programming are therefore done away with completely, thereby ensuring reliable opera-tion with full functional scope for the user.

Automatic occupancy detection and meas-urement of the light in a room are essential for energy-efficient buildings of class A or B. Both functions are combined in the e.control multisensors which cover all applications with the LON interface and are available in various sizes.

e.control light actuators cover all lighting applications. Whether fluorescent lamps, high or low-voltage halogen or LED lamps, relays, dimmers, 1-10V interface or DALI, e.control always has the right actuator - it goes without saying that as energy-efficient solutions which comply with EN 15232 they are, of course, dimmable.

Sensor functions

e.control offers numerous lighting control options: web services for browsers or IP telephones, touch panels or integrated room control devices. All of them allow the light-ing to be switched on/off and dimmed, scenes called up as well as log-on or log-off in the room.

The e.control occupancy evaluation system calculates from the presence detection and manual presence log-on systems the ap-plicable occupancy status of a room for all further application functions of the lighting, sunblind and room climate control systems..

The e.control automatic light is only acti-vated in hallways, sanitary facilities or stor-age rooms if human occupancy has been detected. This prevents energy being used for lighting unused rooms.

The daylight-dependend lighting is used if the dimming option cannot or must not be used for the lighting. Depending on the available daylight, artifi cial lighting is added – in up to 2 stages with e.control. An integrated learning function ensures that the lights are switched off again as soon there is suffi cient daylight.

Automatic lights Daylight-dependent lighting

The constant-light control system provides the best means of saving energy and is therefore a must for energy-effi cient build-ings of class A or B. In daylit rooms, only enough artifi cial light is added to maintain the required level of lighting. In large, low-level rooms with an uneven distribution of daylight, the e.control constant light control system even separates two groups of light-ing in order to ensure a uniform level of illumination. In this way, energy savings of up to 50% can be made.

e.controlTM – sunblind functions

As with the lighting, e.control also offers numerous control options for sunblinds: web services for browsers or IP telephones, touch panels or integrated room control devices. All allow for the positioning of the blind length and slat angle either directly or via scenarios.

Operating functions Slat tracking controlActuator functions

e.control actuators cover the entire range of sunblind systems, whether internal or external blinds, awnings, screens or roller shutters. All devices have a priority control function and support the e.control slat tracking controller including shadow correction. For especially demanding applications, e.control offers SMI actuators due to their high positioning accuracy.

For energy-efficient buildings, tracking the sun in accordance with its position is par-ticularly important for optimising daylight utilisation. The e.control ombra BST slat track-ing controller calculates in cycles the precise angle at which the supply of daylight is maximised despite the lack of glare and transmits this to the e.control sunblind actuators.

* Recall or learn scenes ** Scene memory

In addition to occupancy detection, the calculation of the sun’s intensity and inside room temperature is also required for energy-efficient buildings of class A or B. e.control provides these values by means of multisensors, weather sensors and all room control devices.

Sensor functions

The e.control solar control system on the weather sensors evaluates the daylight on each façade and determines the limit value and delay at which a sunblind is moved into a defined position.

Shadow correction

Each e.control sunblind actuator is able to calculate independently whether its blind is in the sun at any specifi c point in time or whether it is being shaded by buildings or parts of buildings. In periods of shading, therefore, the sunblind is set to maximum daylight provision in order again to improve daylight utilisation considerably.

Automatic thermal control

With the aid of the automatic thermal con-troller the intake of solar heat through the façade is controlled via the sunblind, thereby supporting the heating and cooling system. Whilst the intake of heat is welcome in spring, for example, it prevents unnecessary temper-ature rises in summer by closing the blind.

e.controlTM - room climate control functions

With e.control you have total control over the desired room climate, either via web browser or IP telephone, touch panel or an integrated room control device. In all cases, it is possible to infl uence the setpoint value, fan setting and the outside air supply, if necessary.

In conjunction with the e.control time pro-grams, an start optimisation reduces thermal energy comsumption for individual rooms, such that each room can be heated at the latest possible time.

In addition to measuring the temperature by means of the e.control room control de-vices, an energy-effi cient building of class A also needs to know the occupancy status of the rooms. The values for this are provided by the e.control multisensors.

Actuator functions

e.control actuators cover all applications of air-conditioning technology. Whether they are for radiators, heating/cooling ceilings, fan coils or façade ventilation devices, e.control always has the suitable actuator. All offer sequence adjustment, value limit-ing as well as a valve opening function for longer periods of non-use.

The level of energy effi ciency can be in-creased considerably by adjusting the room temperature to the room occupancy. To this end, all e.control room climate controllers

In addition to individual setpoint shifts by the user, e.control room climate controllers also provide summer/winter compensation in the event of high/low outside tempera-tures. The control response can be com-pletely parameterised by the user.

Setpoint calculation

In addition to the room temperature control function with PI algorithm, e.control room climate controllers also offer the room sup-ply air cascade control function for fan coils with outside air fl ap.

Night-time cooling

Load optimisation

The e.control room climate controllers support the primary system control in optimising the energy supply through the e.control load optimization function. For this, each controller sends its current load to an evaluating logic (in the sistema RC2), which in turn informs the DDC control system as to whether and how the inlet temperature needs to be adjusted to the heating and/or cooling requirements.

All e.control controllers can – depending on the heating/cooling system – be operated in the heating, cooling, automatic, pre-cool-ing and night cooling functions. Switch-over can be performed either via a time program, the building management system or automati-cally via the controller.

Function selectionAll e.control room climate controllers can be switched to the night-time cooling function. Each controller then independently decides on when the night cooling begins and ends, depending on the outside and inside temperature. In addition to outside air fan coils, motorised windows can also be used for ventilation purposes.
