For connection of BGP-COD-BATtoa module, the cable GAP-TPH-CAB must be used. The allocation of the channels is as follows:Channel Default Description addressSync. inputsignal. It is retained permanently, but may be overwritten at any time.Functions and programmingFor transmission of light levels from the light sensors, channel 2 (A2) is used as output for serial data. Channel 1 (A7) is also used for transmittingdata.The channel is used as an input for synchronizing the serial data. In the configuration software for the Controller, the channel must be selected as a "Daylight sync." channel. The Controller will then automatically generate the sync. signal used forthe controller and the light sensor.MountingThe sensor must be mounted in the ceiling and directed towards the floor. It is important to place the sensor where it will not be hit by any direct sunlight during the day. It is also important that the sensor is placed correctly in the room. Since it can be difficult to find the ideal place the first time, it may be nec- essary to change the placement of the sensor if the regulation during the day is not optimum.As a starting point, the sensor should be placed in the area, where the sunlight contributes least to thetotal light in the room. This meansis regulated by a sensor placed within this area, while an area away from the windows is regulat- ed by its own sensor. In this area, a larger amount of lighting will usual- ly be needed to maintain a homo- geneous light level in the room.The sensors must be placed so that they have a free view. This means that no large objects, like big flowers, shelves etc. must be placed under the sensors. In addition, it is important that no kind of up-light is placed near the sen- sors, or that the area around the sensorisnotlitupwithforexample table lamps, which are not1B1for lightlevel dataOnly one channel in the smart- house system needs to be con- figured as sync. channel, independ-that in most cases it will be recom- mended to place the sensor at the back of the room in relation to theconnectedtotheDaylightcon- troller.2A2Light leveloutputThe coding of the sensor can be carried out without smart-houseently of the number of light con- trollers and light sensors.
