with light and timer controls
This timer control enables the light to be controlled very extensively in order to accurately simulate a natural day and night rhythm. The straightforward operation makes it very easy for users to program a light control schedule using different start/stop times and dim cycles. To achieve optimum transparency and ease of operation, the 21 freely programmable timer functions are coupled to the master clock. This minimises the risk of any incorrect settings. Combining the CLK-20 with an electronic light sensor enables considerable energy savings by lowering the lighting intensity as daylight enters.
