Description Purpose and application The TOUCH DIM WCU wall transmitter, in combination with a TOUCH DIM RC radio receiver, enables the wireless control of two luminaire groups, each with up to 15 electronic control gears featuring the TOUCH DIM® function. TOUCH DIM WCU The wall transmitter can be screwed or glued onto smooth surfaces. Function The TOUCH DIM WCU wall transmitter sends radio signals to the radio receiver, which converts these and transmits them to the connected electronic control gears. The wall transmitter does not require batteries and is absolutely maintenance-free. The necessary transmission energy is generated by an integrated inductive piezo energy converter when the pushbutton is pressed. Design The wall transmitter is made up of the following components: A Wall transmitter Operating instructions • Pushbutton for luminaire group (A) connected to channel 1 (Ch 1) of the radio receiver • Pushbutton for luminaire group (B) connected to channel 2 (Ch 2) of the radio receiver B Operation Functionality The radio control system consists of two channels (Ch 1 und Ch 2). The luminaire groups connected to outputs „Ch 1“ and „Ch 2“ of the radio receiver (E) can be independently operated with TOUCH DIM WCU wall transmitters. Basically, the transmitters can be used to operate all TOUCH DIM/TOUCH DIM sensor functions of OSRAM electronic control gear. Ch 1 TOUCH DIM RC The wall transmitters must be trained in the radio receiver. 2x < 30 s 1 2 Note: To train the wall transmitters, see the separate instructions of the TOUCH DIM RC radio receiver. Ch 2 3 2x < 30 s 1 2 Switching on and off the luminaires 3 Via short press. • Upper button: luminaire group on channel 1 (Ch 1) A • Lower button: luminaire group on channel 2 (Ch 2) max 1 2 A 3 max 1 2 B 3 B > 30 s 1 1 2 > 30 s Changing the brightness ... Via long press. • Upper button: luminaire group on channel 1 (Ch 1) • Lower button: luminaire group on channel 2 (Ch 2) 3 2 ... 3 Each repeated long key button press causes a toggle between increased brightness and decreased brightness. Troubleshooting If you cannot remedy the fault, please contact the Customer Service department of the luminaire manufacturer. Luminaire does not function No mains voltage present. à Use a voltage tester to test if mains voltage is present. Illuminants are faulty. à Replace illuminant.
