MODE OF OPERATION The wireless Bxx-WLS4 switches are programmed as standard Fuga/Opus switches (but with no channel coding for (I/O 5-8, as the leds automatically follow the but- tons). The communication between the Bxx-WLS4 wireless switch and the BH4-WBU-230 base is estab- lished in the following way: The used smart-house adresses of wireless devices are all pro- grammed at the wireless device. The only "special" interaction regarding wireless devices is the association process. This process makes sure that your wireless devices are not disturbed by the devices of your neighbour. To associate a device with the base: 1) Press the "mode" button on the base. The association led lights up. 2) Press a button on the wireless device to be associated. - All leds on the device will light up for about 1 second. 3) Press the "mode" button on the base unit until both Association and disabled-leds are off. This indicates "normal operation". If the connection from a wireless device fails, alle leds will flash briefly after trying to communicate with the base unit three times. If a device associated with base A is in sight of bases A and B and you want to reassociate the device with base B, do the following: 1) Select the "Disabled" mode on base A. 2) Select the "Associate" mode on base B. 3) Press a button on the wireless device to be associated. - All leds on the device will light up for about onesecond. 4) Press the "mode" button on both base units until both Association and disabled-leds are off. This indicates "normal operation". The LEDs: The "Power" LED indicates that the unit is powered. (230Vac) The "smart-house OK" LED indi- cates detected smart-house signal. The "RF" LED indicates received wireless communication directed to this base. The "Associate" LED indicates the association mode. The "Disabled" LED indicates that the base ignores any wireless com- munications.
