Astronomical Clock - Allows various scheduled scenarios to occur at preset times.

The ACC-CLK2 is a multi-purpose astronomical clock interface of the DimOnOff Building automation series, which allows various scheduled scenarios to occur at preset times.

It is well suited for lighting applications. One can program the ACC-CLK2 to turn ON and turn OFF the lights with reference to the sunrise and sunsetor dawn and dusk. It has up to three relay outputs(option ACC-CLK3). Each relay can be independently programmed for ON or OFF operation by specifying the time offset and OFF-Hours with reference to sunrise and sunset.
