SCN‐RS1R1.01 Rain sensor SCN‐SS1H.01 Sun sensor for the indoor inastallation on windwows with vacuum cup 2.2. Usage & Areas of use The MDT Weather station Home is made for the weather detection for private use. The installation is made in the outdoor area and should be made on a pole. Alternative, the weather station can be installed on a wall at the southern side. The connection to the bus is made via a 5m long bus cable, which is included in the delivery contents. Three brightness sensors are included in the weather station, which are faced to the sky directions East, West and South (Have a look at the mounting direction – south). These can be controlled via two threshold values and an extensive facade controlling unit for shutter and blinds. Additional a twilight sensor is integrated. Via an individually adjustable wind sensor, the wind speed can be captured and actions can be performed. The temperature sensor, which can be adjusted with threshold values, complete the service portfolio of the weather station.

Illustration 1: Exemplary circuit diagram 2.4 Setup & Installation instructure The weather station is delivered with a 5m connection cable and should be installed on a free standing mast if possible. During assembly is to note, that the weather station will only deliver right values, if the location is chosen well. In this way wrong values can be prevented. The brightness sensors are attached to each other at a 90 ° angle, so the 3 sky directions can be captured. At this point, there are two different opportunities to install the weather station. On the one hand the weather station can be adjusted exactly to the sky directions to capture the exact brightness of the three directions. On the other hand the weather station can be adjusted to the facades of the house for optimal sun protection for the rooms and windows. For detecting the wind speed must be ensured, that the rotating wind sensor can move frictionless. Further more the weather station should not be protected of wind by trees or other obstacles, because otherwise the wind speed can not be captured properly.

Brightness sensor west The brightness sensor for the west direction with the same functions as described above can be parameterized at this submenu. Dusk sensor The dusk sensor is calculated from the maximum of the three brightness sensors. The calculated dusk value can be sent and a day/night recognization can be activated. Wind sensor The wind sensor can capture the current wind speed and cause actions according to adjusted tresholds. So alarms, e.g. for shutter actuators, can be created. Temperature sensor The temperature sensor can be parameterized with up to two tresholds and send telegrams according to the adjusted thresholds.

Technisches Manual Weather station SCN‐WS3HW.01 3 Communication objects 3.1 Overview The communication objects are divided into the 6 functional areas, Brightnes East, South and West, dusk sensor, wind sensor and temperature sensor. For the 3 brightness sensors, an additional facade control can be activated. At first the objects for the 3 brightness sensors are available. Afterwards the objects for the wind sensor, dusk sensor and temperature sensor follow. At last stand the general objetcs. The communication objects of each block start always with the measuring value. On this value the objects for the activated tresholds and facade control follow if activated. A deatilled listing of the communication object is shown at the chart at the following page. The following picture shows an example for the communication objects: Illustration 2: Example of the communication objects MDT technologies GmbH • 51766 Engelskirchen • Papiermühle 1 Tel.: +49-2263-880 • Fax: +49-2263-4588 • knx@mdt.de • www.mdt.de...

Temperature sensor activates the temperature sensor not active active Chart 3: Parameter – General The function “Cyclic send of Operating‐Telegram” shows an telegram, which observes the function of the weather station. Via this object it can be observed whether the weather station is still at the bus or not. This can be done e.g by a homeserver or a visualization. In complex buildings, the error detection can be accelerated by this method and gets much easier. The function “Behavior after programming” defines whether external values, which were read in via objects, should keep valid. The other opportunitie is to overwrite these values with the one of the parameterization. The limitation of telegrams can achieve that the bus gets not overloaded. An overloading of the bus‐ system can cause long waiting periods, e.g. at pushing a button. If the limitation of telegrams is activated and more telegrams than allowed are send, the telegrams above the limitation will be send at the next time interval. Therefore an overload of the bus can be prevented. MDT technologies GmbH • 51766 Engelskirchen • Papiermühle 1 Tel.: +49-2263-880 • Fax: +49-2263-4588 • knx@mdt.de • www.mdt.de...

Attention should be paid to, that a stepping of the threshold value is necessary. That means that the limits of the threshold value 2 must be higher than the ones of the threshold value 1. The following chart shows the stepping of the threshold values 1 and 2: Illustration7: Stepping of the threshold values 1 & 2 It is also possible to program a crossover of the both threshold values insofar as the upper limt of threshold value 2 is higher than the one of threshold value 1 and the lower limit of threshold value 2 is higher than the one of threshold value 1: Illustration 8: Overstepping of the threshold values 1&2 MDT technologies GmbH • 51766 Engelskirchen • Papiermühle 1 Tel.: +49-2263-880 • Fax: +49-2263-4588 • knx@mdt.de • www.mdt.de...

Block object Disply of a blocking object for the no sue facede control use Chart 10: Facade control Data type and moving function The output object for the facede control of the weather station can be adapted to the controlling device via the parameter “data type”. The settings blinds, shutter + slats and scene number are available. The required setting depends to the controlling shutter actuator. Depending to the adjusted settings, the further parameterizing options are displayed. At the blinds and shutter+slats function absolute positions form 0‐100% can be moved to. At the setting scene number, the secenes from 1‐64 can be called. For the first threshold value, a parameter for exceedance and the undercut is available. For the second threshold value is only a parameter for the xceedance is availbale, because at an undercut of the second threshold value, the action for the xeceadnce of the first threshold value becomes active.

Illustration: 10 Diagram facade control The diagram shows an overstepping of the threshold values and the reaction of the blinds to a facade control. Additional a minimum of period for the exceedanvce/undercut is shown exemplarily. The faced control starts as soon as the measured brightness value is higher than the upper limit of the first threshold. From now the measuring of the time for the threshold starts. If the sensor measures an exceedance for the adjusted time, the adjusted function for the exceedance of the threshold will be performed. In this case the blinds are moved to 50%. The blinds stay on this position until the sensor measures an exceedance of the second threshold for the adjusted time. Now the blinds drive to 70%. If now an undercut of the lower limit of threshold 2 is measured for the adjusted time, the first trehold will be active and the blinds will drive to 50%. The blinds stay in this position until the undercut of the lower limit of threshold 1 is measured for the adjusted time. The following areas are valid for the activation of the facade control: Action of treshold 1: upper limit (treshold 2) – upper limit (treshold 1) Action of treshold 2: upper limit (treshold 2) to infinity The following areas are valid for the deactivation: Abolishment treshold 2: Undercut lower limit of threshold 2 Abolishment treshold 1: Undercut lower limit of threshold 1 MDT technologies GmbH • 51766 Engelskirchen • Papiermühle 1 Tel.: +49-2263-880 • Fax: +49-2263-4588 • knx@mdt.de • www.mdt.de...

There is an additional parameter at the general settings, have a look at page 10, which defines whether the Teach‐In values shall be kept after a new programming or the weather station shall overwrite them with the parameterized one. Temperature‐/Blockfunction The facade control can also be parameterized with the influence of temperature. This enables that the facade control gets only active if the temperature is higher than a certain value. The temperature can be read from the internal temperature sensor or from any external. An additional communication object appears if the weather station shall receive an external temperature. The connection to the internal sensor occurs automatically if activated. By activation this function, the faced control is only active above the parameterized temperature. If the temperature falls below the adjusted function, the facade control is deactivated. The blocking object for the facade control allows blocking the facade control with a logical “1”.
