![CDATA[Control unit 1 - 10 V 4-way with manual operation for KNX REG plus Features: The control unit switches and dims electrical consumers that have a 1-10 V interface. 5 device configurations can be selected. This assigns the 4 individually controllable dimming channels to the switching outputs (e.g. 4 dimming channels are assigned to a switching relay to control an RGBW light). Relay outputs that are not assigned to a dimming channel can be used as freely acting switching actuator channels. Reactions to bus voltage failure and return and after an ETS programming process can be set. Manual operation of the outputs independent of the bus with mechanical switch position display. Delay for actively sending feedback after bus voltage return. Logical linking function can be configured for each channel. Up to three central switching functions for the joint control of all dimming and switching channels.]]>
