The dimmer actuator KYMASGARD® DA1- FEM - UP is a device with one channel for in-wall or on-wall installation. Initiated by up to 30 radio transmitters (wall-mounted and hand-held transmitters) a group of ohmic and inductive consumers can be switched and dimmed. Different functions such as crossfade time or time delay can be allocated to the output, depending on the parameter setting. The dimmer actuator DA1- FEM - UP can easily be reconfigured for use as a repeater.
